>>31094101Guzma is perhaps the best. Maxie & Archie are full retards, but they're lovable. Giovanni is bland, but no gen 1 characters have any depth anyway, so it feels cheap to call him bad. Cyrus is solidly evil and insane, but almost no one rates Galactic very high, so it'd be wrong to say he's overrated.
Lysandre is garbage, but he's literally based on Hitler. He is simultaneously insufferable and charismatic, disgusting and bland. Easily the worst. Flare is a joke, and Malva's non-story makes me angry to this day AND makes me hate Diantha & Sycamore even more as a result.
Worst case of wasted potential are the HGSS Rocket Quartet, though, easily.
Also fuck your bait OP, sage
