I have been debating whether to take the
@quickccc article list and posting my own ranking based on those listed, because it is pretty comprehensive. The article is from November of last year, so it would be necessary to add The High Evolution (
Guardians of the Galaxy Vol 3) and Gravik from
Secret Invasion. Gravik is debatable this early on but Episode One puts him solidly on my list.
Some things have made me put off doing so though. For example, some of the villains and their villainy is a consequence of being a pawn. Take Wensu from
Shang-Chi and The Legend of the Ten Rings. His actions were manipulated. Some villains are either not that nefarious in their actions or are flat out jokes (so far). Contessa Valentina Allegra de Fontaine from
Black Widow, etc., as one of the former and Hulkling
from
She-Hulk, Attorney At Law as one of the latter.
Then there are the second-tier villains in the movie or television series. I love Andy Serkis' Klaw but he was a distant second to Ultron in the second Avengers movie. Ditto in
Black Panther to Killmonger.
Knowing me I will eventually do a list. When is the question.
