Since the Pokemon are wild it makes sense. They're more confrontational and probably stronger in some cases. Unless the Pokemon is trained then it will be treated differently. I think too it depends if the Pokemon is young verses being older.

[Levi commented as he continued to observe the two Pokemon playing. It looked as if Foudre was going to treat Togepi gently sensing it being a baby. Nor was Togepi being too rough or toddling off where it shouldn't.]
