Fusion Evolution: Gallatross
Typing: Fighting/Electric
Stats: 86 / 130 / 82 / 95 / 107 / 75 (575)
Ability: Ground Drive - Speed is raised by 1 when hit by a Ground-type move; Ground immunity.
Reasoning behind nomination: I was going to make a submission about how Gallatross is better than Conkelvire, but it's the complete opposite. The only thing that Gallatross provides that Conkelvire doesn't is Ground-immunity on an Electric-type. Conkelvire's ability provides Electric-immunity AND a Sheer Force boost, and it has better attack and better speed. It also has better physical bulk. Gallatross has set-up moves but won't be able to do anything with them due to below average speed and bulk. Not even the Mega can save Gallatross, it still won't hit as hard as Conkelvire. At least the Mega is faster.
Conkelvire and Gallatross were added one after another, so I wondered why. I still don't know why it got in, but I found an old explanation as to why it's worse than Conkelvire.

Hinestly I'd run another mega + Conkelvire, because Poor Gallatross is outclassed as a Physical electric type. While access to Close Combat, Ground Immunity, Swords Dance, Coil, and obscure coverage and support options (Leaf Blade x Will o Wisp) allows it to stand out, Conkelvire's higher speed, power from both sides of the spectrum, better coverage, better overall bulk and access to STAB priority makes Gallatross obsolete. Still it makes for a good mon. Too bad its gonna sit in the outclassed corner with Zapggron, Jellivor and Steelthorn.
Fusion Evolution: Aurantrum
Typing: Ice/Dragon
Stats: 112 / 109 / 105 / 94 / 85 / 74 (579)
Ability: Absolute Zero - Biting and normal-type moves used by this Pokemon are treated as being ice-type in addition to their usual type and receive a 30% power boost.
Reasoning behind nomination: This sucks. Dual-type moves suck. The way it's worded, Normal type moves become Normal/Ice. It becomes an Ice move with no effect on Ghost, 4x resist from Steel, 2x resist from Rock. Bad idea. Thunder Fang becomes the fabled Electric/Ice combo, but combined into one move it sucks. It becomes useless against Ground, neutral against Dragon, Grass and Water. I mean it gets 4x against Flying but is it really worth it? The answer is no. I could go on, listing Fire/Ice, Dark/Ice and Poison/Ice combinations, and they're definitely the least bad but also suck. The only mildly interesting Fang move is honestly Ice Fang, but only if the ability makes it double Ice type (dealing 4x damage against Ground, Dragon, Flying and Grass PLUS 30% boost PLUS STAB). I doubt it works like that though.
Fusion Evolution: Miminja
Typing: Dark/Ghost
Stats: 63 / 112 / 78 / 76 / 88 / 124 (541)
Reborn: 63 / 162 / 78 / 126 / 88 / 134 (651)
Ability: Resurrection - When this Pokémon gets KOed for the first time, it gains 50% of its original HP and changes to Reborn form.
Reasoning behind nomination: Enough outclassed fusions, here's a broken one. This thing basically has a free turn to use whatever set-up move it wants, no matter what you do or how good your predictions are. Of course it'll use Swords Dance, with 162 base attack, STAB priority and coverage moves up the ass, it can pull a sweep pretty easily. Miminja-Reborn also sits confortably at a great speed tier, with a great defensive type combo. Below are some calcs.
+2 252 Atk Life Orb Miminja Night Slash vs. 252 HP / 252+ Def Hazmat Fur Bezong: 252-299 (58.6 - 69.5%) -- guaranteed 2HKO
+2 252 Atk Life Orb Miminja Night Slash vs. 252 HP / 252+ Def Cofagreelix-Mega: 289-343 (81.1 - 96.3%) -- guaranteed 2HKO
+2 252 Atk Life Orb Miminja Night Slash vs. 252 HP / 252+ Def Rhyperlax: 242-285 (48.5 - 57.2%) -- 91.8% chance to 2HKO
+2 252 Atk Life Orb Miminja Gunk Shot / Wood Hammer vs. 252 HP / 252+ Def Dialcatty: 152-179 (40.6 - 47.8%) -- guaranteed 3HKO
+2 252 Atk Life Orb Miminja Play Rough vs. 252 HP / 252+ Def Fluffy Fur Perwear-Alola: 255-302 (62.5 - 74%) -- guaranteed 2HKO
Miminja would probably do more than that to the best walls in the meta. Who would run max HP max Defense on physical walls in the first place? I don't see many max SpD Chanseys running around in OU, I imagine it would be the same for Fusion Evolution.
As for Fairy-type revenge killers
+2 252 Atk Life Orb Miminja Shadow Sneak vs. 0 HP / 0 Def Sceptette-Eternal-Mega: 253-298 (88.7 - 104.5%) -- guaranteed OHKO after Stealth Rock
+2 252 Atk Life Orb Miminja Shadow Sneak vs. 0 HP / 0 Def Melon: 507-601 (151.3 - 179.4%) -- guaranteed OHKO
+2 252 Atk Life Orb Miminja Shadow Sneak vs. 0 HP / 0 Def Absoko-Mega: 131-155 (47.6 - 56.3%) -- guaranteed 2HKO
+2 252 Atk Life Orb Miminja Shadow Sneak vs. 0 HP / 0 Def Entaria-Mega: 172-203 (51.9 - 61.3%) -- guaranteed 2HKO
+2 252 Atk Life Orb Miminja Shadow Sneak vs. 0 HP / 0 Def Altarigarde-Mega: 165-196 (51 - 60.6%) -- guaranteed 2HKO
The rest of the Fairies gets outsped, all of them, no joke. They would need to run Scarf.
Food for thought. You know how Zygarde-Complete changes its HP stat, making it recover HP? If we used the reverse logic for Miminja, imagining its 50% HP recovery as an HP stat boost, it would have 129 HP and effectively 717 BST.
Fusion Evolution: Rebell
Typing: Fighting/Psychic
Stats: 70/85/80/67/80/100 (482)
Ability: Tinkering - This Pokemon's status moves and moves that switch the user out have +1 priority. this Pokemon heals status conditions upon switching out.
Reasoning behind nomination: In a metagame where over 20 fusions have some sort of extra priority ability, Rebell fails to stand out.
For dedicated Prankster sets, Comcott is a better option due to +3 priority instead of +1, and Taunt+Encore as opposed to T-Wave. Don't get me wrong, Comcott and Rebell have many, many differences, I'm talking about a specific priority-utility set.
For pivotting, Scipod is an infinitely better choice. We're comparing 60BP STAB Bullet Punch (gets switch-out effect from the ability) off of 137 base Attack VS 70BP non-STAB U-Turn off of 85 base Attack. Rebell heals status when switching out, but Scipod is immune to Toxic in the first place, the most common status, so it's overall a better pivot.
If for some reason you want specifically a Fighting-type Prankster-clone user, then there's Theye with better bulk and Sableye's WoW+Taunt+priority Knock Off. Theye has less survivability overall due to needing to be statused, while Rebell heals status. However, both have Recover, and Theye has higher attack and priority Superpower as opposed to High Jump Kick, so again, if for some reason you want specifically a Fighting-type Prankster-clone user, Theye is a better choice.
Fusion Evolution: Tapu Jojo
Typing: Ice/Electric
Stats: 67/82/60/125/85/132 (551)
Ability: Supercharge Surge - Summons Supercharge Terrain upon switchin (effects identical to Electric Terrain) and reveals the most powerful move in the opponent’s moveset. As long as Supercharge Terrain is active, this move is considered Electric-type.
Reasoning behind nomination: Honestly the ability seems like a pain in the ass to code. It creates a new terrain with different name, with effects identical to an existing terrain JUST to remove Ice weaknesses (assuming it's "this Pokemon is considered Electric-type" not "this move"). We have 7 Ice/Electric fusions already, removing this one won't make much of a difference.
