Can my active pet be affected by anything that could change it in any way? (Random event's mostly)

Kind of a weird question, I know. But it's been bugging me.

No there an't any REs that can harm your pet on subeta.

Alright, thank you ^^

there is a random event that can cause your active pet to gain stats, which is why most of us keep our battle pets active. But no bad ones.
