Viper / Madame Hydra ?
Doctor Minerva ?
(who is a main foe of nearly anybody who uses Marvel as a name anyway ...)
Probably, there is also Doc.X ...
Quote:She-Hulk (is it Titania???)
Yes, Titania is the only famous villain in her rogues gallery who could be considered one of her personal archfoes.
In the first She-Hulk series, Nicholas Trask, Beverly Cross and Doc were three attempts to give She-Hulk her own archfoes.
Ultima & her father, the Word, might have become main foes but they only battled her on one occasion.
... but, anyway, all these obscure characters are totally forgotten, nowadays.
This question is easier : Spider-Man, Simon Stroud, Martine Bancroft and Vic Slaughter.
In a way, probably more than any other Marvel character, Morbius is his own worst enemy.
Quote:Captain Marvel (Carol)
See the link below for the detailed information :
Carol Danvers has a lot of archfoes : Supreme Intelligence, Brood Queen, Deathbird, Grace Valentine, Skrulls (especially War-Skrulls) ...
Unfortunately, I think that Marvel never cared enough about Monica (and that's a shame) to give her a proper rogues gallery. The villains appearing in the Nextwave comic book might be regarded as her main foes.
Quote: Nova (Rich, not counting Annihilus)
The Sphinx, Condor, Diamondhead
I honestly don't know ...
Probably, Titus ?
Aaron Davis ?
I had to look for her list of enemies to guess what could be the answer.
Tabur and Kraven the Hunter might be her main foes.
Buzz Baxter (Mad Dog)
When she was dating Daimon Hellstrom, Satan (Marduk Kurios) was one of her main foes.
