One strange punching bag.
Wobbuffet is one of my favorite Pokémon ever and I have never used him on a team in any game. My love for Wobbuffet is based mostly on its appearances in the anime in which he belongs to Team Rocket member Jessie, and has remained a go-to member of her team since his arrival.
I love Wobbuffet because of how gloriously weird he is. His penchant for popping out of the Pokéball and shouting, “WOOOBBUFFET!” at inopportune moments. What makes him so great, though, is that he’s incredibly overpowered in the anime. His ability to reflect attacks back at opponents makes him basically invincible, but due to his (and his owner’s) incompetence, he’s always unable to turn this into an advantage.
Everything about Wobbuffet is endearingly strange, from his design with its always-closed eyes, to the adorable salute he gives when he appears. Wobbuffet always made me laugh as a kid when I watched the anime, and I still find him absolutely hilarious today.
