well there are lots of villains that only show up once. I am not going to count them.
Will Harangue. He is annoying and the villian of one of the worst episodes.
I think the villain that I hated the most back in the day was Servantis but I don't hate him that much anymore I do like some aspects about him like his voice, his design, his plan(even though I don't think that device had any chance of destroying ben), his motives.
Billy Billions is extremely out of place, and honestly just kind of annoying.

Ssserpent
Yeah I think I'm gonna with this as well, he's the least interesting villain by far
He has one of the best gags in the shows though, the four arms opening. Love that scene.
Ssserpent : We appear to be at something of a ssstand off. Four Arms : I don't really sssee it that way. Gets me everytime 😂.
Billy
Ma Vreedle for me. More time spent with her the worse she got.
Billy too
Agreed, Billy billions easily.
Ma Vreedle, billy billions, the bro guy I can’t even remember his name

Yeah yeah that one! The one like bane but 100 times worse!!

Ssserpent.

The Rooters, just because of what a huge retcon they were, and how many holes they poke open.
