Typhlosions a walking volcano. Espeon could turn your brain into mush anfd make you do it's bidding.. Blazekin could tear you in half with a kick without even using it's talons probably.. Lapras is supposedly chill, but you better wear some damn good noise canceling headphones if it starts singing (perish song)
Honestly even butterfree could kill you if we're applying irl rules here you might need a hazmat suit to touch it, but I'll stop. 😆
edit: Espeon doesn't evolve and get psychic powers until it loves it's trainer enough to develop precognition specifically to protect that trainer though so it's probably a good one to have.
