Best Ditto Fusions in Pokémon Infinite Fusion: What Actually Happens When You Fuse Ditto
What happens when you fuse Ditto in Pokémon Infinite Fusion? The short answer: yes, you can fuse Ditto, and the result is far less weird than most players expect. Ditto is a pure Normal type, so every Ditto fusion carries Normal typing, the sprite follows the standard head/body rules, and the fusion is fully reversible. There is exactly one strategic reason to fuse Ditto, and it is a good one: an Imposter Ditto fusion, the famous “Imposter Blissey At Home” build with 186 HP that community guides have praised for years. This guide explains the real mechanics behind every ditto fusion pokemon infinite fusion players attempt, corrects the misconceptions, and shows you the Imposter build step by step in version 6.7.2.

Can You Actually Fuse Ditto?
Yes. The official Infinite Fusion wiki’s Fusion FAQs state plainly that any two Pokémon can be combined with each other to create a fusion, and Ditto is not on any exclusion list. There is no special restriction, no hidden flag, and no glitch: you open the fusion menu, select Ditto and a partner, pick a DNA Splicer, and choose your head and body like any other pair. The fusion acts as a regular Pokémon with its own moveset, stats, and Pokédex entry, exactly like every other fusion in the game.
This surprises players because Ditto is strange in the official games: it breeds with almost anything, it cannot breed with itself, and its whole identity is transformation. None of that carries over as a restriction here. The fusion system treats Ditto like any other single-typed Pokémon. The only thing Ditto changes is the result, because its typing, stats, and abilities are so unusual. The rest of this guide walks through exactly what those quirks do to the fusion math.
One edge case worth answering directly: you can fuse Ditto with another Ditto. The wiki confirms that two Pokémon of the same species can be fused to create a self fusion, which keeps the same stats as the base species and only gains a 50 percent XP bonus. A Ditto/Ditto fusion is therefore a normal Ditto that levels slightly faster. It is a curiosity, not a strategy, and this guide will not pretend otherwise.
What Your Ditto Fusion Will Look Like
Ditto fusions look like every other fusion: they follow the head and body sprite rules. The wiki’s Fusion Basics section explains that the head Pokémon determines the colour palette and pattern, while the body’s shape carries through. So a fusion with Ditto as the head keeps Ditto’s blob face and smile, recoloured in the partner’s palette, on the partner’s body shape. A fusion with the partner as the head keeps the partner’s face and features with Ditto’s pink or purple palette bleeding through.
You never have to guess. When you fuse in-game, the fusion menu shows you previews of both orders before you commit, and a green-tinted preview means a custom community sprite exists for that pairing. The Infinite Fusion sprite community has made thousands of hand-drawn fusion sprites, and Ditto pairings have produced some famous ones: the community notes that Deoxys/Ditto fusions reference the Among Us impostor, and the Mr. Mime/Ditto fusion is widely cited as one of the most disturbing sprites in the game, a gooey humanoid that barely holds its form. Because custom sprites are added in monthly sprite packs, the exact appearance of any given Ditto pairing can change between versions, which is why the in-game preview is the only source of truth for what your fusion will look like right now.
If the pairing has no custom sprite, the game’s automatic sprite system still produces a blended result from the head and body parts. Either way, you see it before you spend the splicer. There is no risk of fusing blind.
The Typing Rule That Decides Every Ditto Fusion
This is the part most guides get wrong or skip entirely. Ditto is a pure Normal type with no secondary type. Apply the standard fusion typing rule, head’s primary type plus the body’s secondary type (or the body’s primary type when it has no secondary), and the outcome is forced: every ditto fusion in pokemon infinite fusion involves the Normal type. Ditto can never donate anything else, because it has nothing else to donate.
Worked examples make this concrete. Put Ditto as the head and Gyarados as the body: the head donates Normal, the body donates its secondary type, Flying, giving you Normal/Flying. Reverse it, Gyarados head and Ditto body: the head donates Water, Ditto’s body has no secondary type so it donates its primary Normal, giving you Water/Normal. Same two Pokémon, two different typings, and the order is the whole decision, exactly as with every other fusion.
When both donations are Normal, the redundancy rule collapses the result to a single type. Blissey head + Ditto body is pure Normal: Blissey’s head donates Normal, Ditto’s body donates Normal, and the game gives you a monotype instead of Normal/Normal. The same happens with any pure-Normal partner in either slot, and obviously with Ditto + Ditto. For dual-typed partners the result is Normal/[type] or [type]/Normal depending on the order, which means Ditto fusions always share Normal’s single Fighting weakness plus whatever the partner’s type adds. Run every order through the Pokémon Infinite Fusion calculator before you fuse, because a flipped order can hand you a 4x weakness you did not plan for.
Why does this matter for the “best Ditto fusions” question? Because it means there is no meaningful ranked list of Ditto fusions. Every Ditto fusion plays by identical typing logic: Normal plus the partner’s contribution. The partner’s stats and ability are what vary, and only one ability in the game makes that variation matter strategically. Which brings us to the entire point of this article.
Ditto’s Stats: All 48s, and What That Means
Ditto’s official base stats are 48 in every stat: HP, Attack, Defense, Special Attack, Special Defense, and Speed. It is one of the flattest stat lines in the franchise. Under the fusion stat formula, Attack, Defense, and Speed lean two-thirds toward the body, while HP, Special Attack, and Special Defense lean two-thirds toward the head. Plug Ditto into either slot and the 48 drags down whichever stats its slot controls.
A Ditto head gives you roughly two-thirds of the partner’s nothing plus one-third of 48 on HP, Special Attack, and Special Defense: thin numbers, every time. A Ditto body does the same damage to Attack, Defense, and Speed. The one slot where Ditto’s presence is nearly free is the body of an Imposter build, because a transformed Pokémon uses the target’s stats instead of its own. That single interaction is why the Imposter fusion is the only Ditto fusion worth building, and why the partner choice for that build is almost entirely about HP.
The honest summary: Ditto contributes nothing positive to any fusion except its ability. Its stats are dead weight, its typing is the bland Normal type, and its movepool beyond Transform is thin. So the whole strategy of fusing Ditto reduces to one question: can the partner’s ability justify the fusion? For one ability, the answer is yes.
Imposter: The One Ability That Makes Ditto Fusions Worth Building
Ditto’s hidden ability is Imposter: the Pokémon transforms into the opponent the moment it enters battle, copying the foe’s stats (except HP), moves, ability, and typing without spending a turn. The official Infinite Fusion wiki confirms that a fusion can use any of the abilities of the fused Pokémon, and that at fusion time you choose between the two abilities the parents actually had. Fuse an Imposter Ditto with a partner, pick Imposter at the fusion screen, and the fusion transforms on switch-in like a regular Ditto would.
This is the famous “Imposter Blissey At Home” concept that the community’s GameBreaker discussion documents: fuse an Imposter Ditto with a Blissey head, and the result has roughly 186 HP (Blissey’s 255 HP weighted two-thirds toward the head, plus Ditto’s 48 at one-third). That is nearly four times Ditto’s native 50 HP, and it fixes Imposter’s classic weakness: the real Ditto is so frail that it often dies before its stolen stats matter. The fusion keeps its own 186 HP while attacking with the opponent’s stats, which makes it a dramatically better revenge killer and scout than a plain Ditto.
The same discussion notes the secondary use that makes this build special: because it attacks with the target’s stats instead of its own, the Imposter fusion can weaken wild Pokémon without overkilling them, and it can use Soft-Boiled (Blissey’s signature healing move, available in the shared movepool) outside of battle. That combination makes it a genuinely good catching and support Pokémon, not just a gimmick.
Getting an Imposter Ditto in Infinite Fusion
Imposter is Ditto’s hidden ability, so a random wild Ditto will almost always have Limber instead. The community documents two routes to an Imposter Ditto. The reliable one is the Ability Ball, a special Poké Ball added to Infinite Fusion that can catch a Pokémon with its hidden ability; the game’s own changelog lists the Ability Ball among the special balls available from the second Poké Mart clerk. The second route, per the community’s GameBreaker notes, is a Dream World outbreak event that can spawn Imposter Ditto directly. Either way, confirm the ability on your Ditto’s summary screen before fusing, because the fusion screen only offers the abilities the parents actually have.
Do not fuse a Limber Ditto and hope for the best. The ability you bring is the ability you get, and a Limber Ditto fusion is just a bad Normal-type with 48-weighted stats. The Imposter Ditto is the entire build; everything else is details.
The Partners That Get the Most From Imposter Ditto
Since a transformed fusion uses the target’s stats except HP, the partner’s job is to donate as much HP as possible while adding nothing harmful. The partner always goes on top as the head, because HP leans two-thirds toward the head, and the typing result is pure Normal in the best cases, which carries only the single Fighting weakness and becomes irrelevant the moment Imposter triggers. The honest shortlist, with the 6.7.2 stat math:
Blissey (head) + Imposter Ditto (body): the classic, ~186 HP
Resulting type: pure Normal. Blissey’s 255 base HP becomes roughly 186 on the fusion, and the movepool brings Soft-Boiled for out-of-battle healing plus Blissey’s enormous support movepool for the rare turns you spend untransformed. This is the build the community discussion is built around, and the math checks out. The only real cost is that Blissey is a late-game or post-game acquisition in most playthroughs.
Chansey (head) + Imposter Ditto (body): the budget version, ~182 HP
Resulting type: pure Normal. Chansey’s 250 base HP lands around 182 on the fusion, four points behind Blissey, with the same Soft-Boiled access. If you have a Chansey but no Blissey, this is nearly identical in practice. The Eviolite, which boosts the defenses of unevolved Pokémon, is worth noting here: the community discussion flags that fusions with unevolved bodies can hold it, though for a pure Imposter revenge-killer role a Choice Scarf is usually the better item.
Wobbuffet (head) + Imposter Ditto (body): the Psychic twist, ~142 HP
Resulting type: Psychic/Normal. Wobbuffet’s 190 HP gives roughly 142 on the fusion, noticeably less than the pink blobs, but the typing is interesting: Psychic/Normal has two weaknesses (Bug, Dark) and one immunity (Ghost), versus pure Normal’s single Fighting weakness. In practice the typing barely matters because Imposter copies the foe’s typing on entry anyway, so take this only if Wobbuffet is what you have available.
Snorlax (head) + Imposter Ditto (body): the early-ish tank, ~122 HP
Resulting type: pure Normal. Snorlax’s 160 HP becomes roughly 122 on the fusion. That is a real downgrade from the Blissey line, but Snorlax is far easier to obtain, and 122 HP is still more than double a plain Ditto’s 50. If you want the Imposter concept running before the late game, this is the honest compromise pick.
Notice what is missing: there is no fifth, sixth, or tenth pick, because beyond high-HP heads the partner stops mattering. A Dragonite head or a Gengar head adds nothing to an Imposter fusion; the transformation overwrites everything except HP. Any “top 10 Ditto fusions” list you see elsewhere is inventing distinctions that the game mechanics do not support.
Building the Imposter Fusion, Step by Step
The build is cheap, which is part of its charm. A regular DNA Splicer costs ¥300 at any Poké Mart, and you will want the fusion preview to confirm the head/body order before you commit. The practical sequence: catch or convert your Imposter Ditto and confirm Imposter on its summary screen; level or obtain your chosen head partner; open the fusion menu and place the partner on top as the head with Ditto as the body; at the ability prompt, select Imposter, not the partner’s ability; and set the moveset from the shared pool, keeping Transform available for the turns before Imposter triggers and Soft-Boiled for support duty.
Two mechanics details from the wiki are worth knowing before you fuse. First, fusing returns held items to your bag, so strip the parents’ items first. Second, and more useful: if you ever unfuse, the head’s ability is rerolled while the body keeps its original ability. Because the recommended order puts Ditto as the body, your Imposter Ditto survives an unfuse with Imposter intact, ready to be re-fused with a better partner later. If you had put Ditto on top as the head, unfusing would reroll the ability and you could lose Imposter. Order matters twice here: once for the HP math, once for the insurance policy.
In battle, the standard play is the Choice Scarf revenge-kill: switch the fusion into a boosted setup sweeper, let Imposter copy its stats and boosts, and attack first with the scarf. Because the fusion’s own Attack and Speed are Ditto-weighted garbage, it does nothing useful untransformed, so never leave it in against something it cannot copy profitably. For catching duty, the Soft-Boiled support set with no scarf lets you heal your catcher mid-fight while threatening nothing.
Fusing Ditto Without Imposter: Mostly a Novelty
A Limber Ditto fusion is, bluntly, a bad Pokémon. Limber prevents paralysis, which is a fine ability on a real team member and a wasted slot on a fusion with 48-weighted stats and Normal typing. There is no hidden synergy to uncover: the stat line cannot be salvaged, and no partner ability available at fusion time fixes the 48s. If your Ditto does not have Imposter, do not spend a splicer on it for competitive reasons.
The one legitimate reason to fuse a regular Ditto is the sprite. The community’s custom sprite artists have a visible fondness for Ditto pairings: the Mr. Mime/Ditto fusion is documented as one of the most unsettling sprites in the game, and several Ditto fusions reference the Among Us crewmate and impostor designs. If you collect funny or cursed fusion sprites, Ditto is one of the best partners in the game for that hobby. That is a real use case, just not a battling one, and this guide will not dress it up as one.
Breeding, Unfusing, and Reversing Ditto Fusions
Three mechanics questions come up constantly, and the wiki answers all three plainly. You cannot breed a fusion, full stop, so a fused Ditto cannot be used for breeding until you unfuse it. This surprises players who think of Ditto as the franchise’s universal breeder, but in Infinite Fusion the fusion is a new species and the daycare will not take it. If you need your Ditto back for breeding duty, unfuse first: unfusing returns both original Pokémon.
Unfusing always returns both parents, and the process is cheap: the same DNA Splicer you fused with works in reverse. There is one quirk to plan around, noted above: the head’s ability is rerolled on unfuse while the body keeps its ability, so keep valuable abilities (like your Imposter) on the body side of any fusion you might one day split.
DNA Reversers flip a fusion’s head/body order for ¥300 after the first gym badge. For Ditto fusions this is genuinely useful: if you fused Ditto as the head and got Normal/[type] but wanted [type]/Normal, a reverser fixes it without a second Ditto. Test both orders in the fusion preview first, but know the reverser exists as a safety net. Our Pokémon fusion tool guide covers the preview workflow in detail.
Ditto Fusion Questions, Answered
Can you fuse Ditto with a legendary?
The fusion system allows any two Pokémon to be combined, and Ditto is no exception. A legendary head with a Ditto body follows the same rules: the head donates its primary type, Ditto’s body donates Normal, and the stats lean toward the legendary parent’s slot. Whether any given legendary is obtainable and fusable in your version is a separate question; check the current Infinite Fusion Pokédex for availability in 6.7.2.
Does a Ditto fusion keep Transform?
The moveset is chosen from both parents’ moves at fusion time, and the Move Tutor on the top floor of Pokémon Centers can teach moves from either original Pokémon later. So yes, Transform stays available, though on an Imposter build you will rarely click it: Imposter already transformed you for free on switch-in.
Why is my Ditto fusion pure Normal instead of Normal/something?
Because the partner’s donation was also Normal. When the head donates Normal and the body donates Normal (any pure-Normal partner as the body, since Ditto’s body always donates Normal), the redundancy rule collapses the result to a single Normal type. This is correct behavior, not a bug: Blissey head + Ditto body is pure Normal by design.
Is a Ditto fusion actually good in battle?
Only the Imposter build, and only in its revenge-killer and catching-support roles. Every other Ditto fusion is outclassed by fusing the partner with literally anything that has real stats. Do not fuse Ditto expecting a strong generalist; fuse it for Imposter, or for the sprite.
What happens to my Imposter Ditto if I unfuse?
The body keeps its original ability, so a Ditto fused as the body keeps Imposter through the unfuse. The head’s ability is rerolled. This is why the recommended order (partner head, Ditto body) doubles as insurance: you can always get your Imposter Ditto back intact.
The Honest Bottom Line on Ditto Fusions
A ditto fusion in pokemon infinite fusion is one of the most misunderstood mechanics in the game, mostly because players expect Ditto’s weirdness to produce weird results. The reality is refreshingly mechanical: Ditto is a pure Normal type with 48s across the board and one extraordinary hidden ability, so every Ditto fusion is Normal-typed, statistically limp, and strategically pointless, except the one build that inherits Imposter. That build, the 186-HP Imposter Blissey-style fusion the community has documented for years, is genuinely good: a bulky revenge killer and a peerless catching support that costs one ¥300 splicer to create and can be unfused without losing the Ditto.
So fuse Ditto once, for Imposter, with the highest-HP head you own, and verify the order in the fusion calculator first. For everything else, spend your splicers on partners with real stats, and if you are starting fresh, download Pokémon Infinite Fusion version 6.7.2 to make sure the mechanics above match your build. The gooey sprites are free; the good fusion costs one good Ditto.
