Tell about times you have deleted others pokemon for whatever reson, i'll start

when i was little my brother is a horrible winner and would tell me how hes pokemon killed mine all the time,
i deleted a Leavanny because i had 5 water types,
i also deleted a Samurott that came from an egg i gave him from my samurott out of my kindness, next battle we had he got my Samurott low and then switched to hes Samurott to finish it saying he's is way better then mine,
i also deleted a Growlethe he was ev training back in gen 5 when it took a lot of time, don't remember why but probly cuz he was an asshole. pic unrelated
