Jigglypuff is one of the cutest and cuddliest looking Pokémon, which makes him the most commonly underestimated Pokémon as well.
Because his hypnotic singing ability is extremely hard to resist, and even the toughest characters fall victim to his charm ability and fall fast asleep when he starts singing his Jigglypuff Song.
But metalhead THEoneNILS thought Jigglypuff's cute little song needed a heavy metal makeover, so listeners will start banging their heads instead of nodding off.
THEoneNILS wasn't the first person to think heavy metal when they saw Jigglypuff perform, and this video still wins the award for most ridiculous Pokémon themed mashup of all time.
