This is a difficult question haha I’m not familiar with the Pokémon franchise but if I had to pick a favourite it would be this dude (he looks like Godzilla, which is why I like him lol)
Pretty sure his name is Tyranitar
This probably isn’t a full answer, sorry don’t know much about Pokémon :(
This is one weird question lmao, okay..
I think I could probably take on most of them, I may or may not get tired but I still think I would have a bit of energy to fight some of them
