He can did you watch kuro's livestream on what ben can and can't turn into?
Kuro only says maybe, and on classic ben10 wiki, djw says omnitrix cannot scan pokemon, but nemetrix can scan pokemon
It whold be cool if the omnitrix had any ultra beast
So far the only Pokemon with Enough Sentience is Mewtwo and maybe Deoxys.
I think the Pokémon has to be intelligent enough but there could be more factors
It really depends on the pokemon, Kuro explained that as an example Charmander couldn't be in the omnitrix. but mewtwo yes
Deoxys was stated to be a space virus that went through mutation but his behavior clearly shows him to be non sentient
For the millionsth time the omnitrix has a pokemon transformation the pokemons intelligence doesnt matter
What do you think?
