Hard to say, especially since this could be interpreted in a number of ways, & there's so many characters on the wiki.

In terms of strength:

Hard to narrow it down to one, but based on their wins & losses, as well as the reasoning for said results, I'd say Chaos from Sonic. Some people use the "defeated by base Sonic" claim, others use the "slowest Sonic character" claim, & it honestly gets me pretty salty.

Honorable Mentions: Most characters from Digimon

It's a toss up between "Rosalina reset the universe", & "Ganondorf's immortal", which is untrue & NLF respectively.

Honorable Mentions: Goku

In terms of popularity:

Cyborg Kuro-chan is probably the most underrated. Even I barely knew about him when I first saw him on the wiki. You could ask anyone, & they probably wouldn't know him or his series.

Honorable Mentions: Any character from Spectrobes, Fossil Fighters, or Bionicle, E102-Gamma

Very hard to say. Most characters I find overrated are from series I'm not familiar with (Megaman, Naruto, etc.), have a good reason for being so (Mario, Sonic, etc.), or can't be narrowed down to one (Pokemon).

Overall: Any character from Street Fighter, Mortal Kombat, or Dragon Ball
