Reminds me of the Pokemon Master in Super Smash Bros. Brawl. The three Pokemon had weakness for fire, grass and water… But of all the other characters in the game, there are a ton of fire attacks, zero grass attacks, and maybe one or two water attacks. So it basically amounted to a debuff for Ivysaur.

Edit: I looked this up, there are actually ONLY fire attacks from other characters. https://www.ssbwiki.com/Type_effectiveness
