One punched by a giltch!

The mutant flu morty one shots any other morty regardless of type or amount of health, he is a rock type? Why does he one shot a decent paper type!!! He was the last morty before I got the badge from the Rick, he was level 47. He shouldnt have been that strong, he wasnt that strong before the update
