when i was a kid and first got ruby (the first game with a pokerus) i caught a poochyena as the first capture. i goo to the pokecenter and the say it hs a virus. i get freaked out and deposit it in the box because i don't want it getting my other guys sick. years later, i still have that virus going through all of my team. first possible pokemon that i could get with a pokerus had it (unless you count mudkip or he poochyena you battle to save birch)

pokerus was gen 3
