I might be stretching the definition a bit and many of these would probably fall into trivia, but these are all Pokemon that I think of that could still count as fusions:
- Weezing is stated to be a fusion of two Koffings
- Vanilluxe is made from two Vannilish melted together
- Dugtrio is said to be "Formed when three Diglett combine."
- Barbaracle is a fusion of sever Binacle
- Zygarde is a fusion of its core and multiple cells
- Original Dragon exists only in legend, but it's a fusion of Kyurem, Reshiram and Zekrom
- Spiritomb is made out of fused spirits
- Basculegion is a fusion of dead Basculin
- Galarian fossils and Type:Null/Silvally are in theory fusions of multiple Pokemon
- Tatsugiri fuses with Dondozo
- Dipplin and Hydrapplin are two and seven wyrms joined in one apple
- Wishiwashi's School Form is a fusion of multiple Wishiwashi
- Melmetal is a combination of multiple Meltan
- Combee can fuse into "wall of Combee"
- Maushold's babies are said to "just appear one day"
- Starmobile is a fusion of Revavroom and two Varoom
- Some Pokemon carry other Pokemon on their body in their arts and are considered a part of it: Matine with Remoraid, Drakloak/Dragapult hold Dreepy, Cramorant has Arrokuda/Pikachu in its beak, Kangaskhan holds a baby.
There's also a few Pokemon that can split and join together again like: Exeggcute, Doublade, Stakataka, Falinks, Probopass, Corviknight, Klang, Klinklang.--Rocket Grunt 11:03, 5 January 2024 (UTC)
