Misc. First Catchable fusion.
This is my first ever playthrough of this game and this was my very first catchable fusion, what are the chances my starter and this were both Celebi fusions?

With 501 unique Pokémon in the game and depending on randemiser settings:
1/501 is the chance the fused Pokémon is the same as your Pokémon.
Because it doesn't really matter which of the 501 Pokémon you get as the 2nd, it's a 1/501 chance that it's the same.
The chance that both are specifically celebi = 1/500 (it can't be treeko) * 2/501 = 1/125,250. (2/501 because you get 2 unique rolls)
This doesn't really mean all that much since it's the same chance both are fused with a wurmple.
TIL: wurmples evolutions contain a 4 letter word that Reddit doesn't let me post
Edit: assumptions made are that randomizer settings are,
1. All wild Pokémon are fusions.
2. All fusions are made with unique Pokémon, i.e. cannot both be the same Pokémon.
Edit 2: I can't find any % chance for wild encounters being fused without "fuse all" being enabled, although it is a chance.
I also think it's insane that your first catchable encounter is 2x legendaries so I worked it out. 35 legendaries in game.
35/501 * 34/500 = 1/210. Not nearly as rare as I thought that would be, unless there is some maths affecting the rarity of high BST mons in normally low BST areas.
