Marvel Studios [VIDEO] (along with their counterparts DC and Warner Brothers [VIDEO]) are continuing to build upon their already mammoth film franchises. As they introduce new complex heroes and return established ones, they also need villains for them to combat. Speculation has been ripe regarding which members of Marvel's "rogues gallery" could be featured next. According to Screen Rant, supervillain Hydro-Man could make his live-action debut in "Spider-Man: Far From Home." Some villains might be chosen to face their traditional foes from the comics. But, in an extra twist, some might be brought in to face somebody they don't usually encounter in the comics.

Projects aren't limited to the Marvel Cinematic Universe. Other ventures include Sony's plans to make a series of films focused on Spider-Man villains. Starting with 2018's "Venom," Polygon reports there are currently plans for nine films in the series. Other fan-favorites could be next in line.

Annihilus

A tyrant from another universe, Annihilus has been a particular antagonist for the Fantastic Four and Thor. The character was originally slated to be featured in 2015's "Fantastic Four." However, he would be cut from the script.

MODOK

MODOK was originally George Tarleton. Tarleton was an employee of a villainous arms manufacturing company who underwent an experiment to increase his intelligence. The experience worked, but it also mutated his body, particularly his head, leaving him unable to walk.

MODOK was under consideration to be featured in "Captain America: The Winter Soldier." Marvel screenwriters Christopher Markus and Stephen McFeely have also indicated their desire to feature the character in a movie.

Taskmaster

Tony Masters was diagnosed with a unique form of photographic memory as a child. He would grow up studying the powers and techniques of various heroes and villains. He is later injected with an elaborate steroid concoction. As a result, he can learn his opponents' skill almost instantaneously

Enchantress

Not to be confused with DC's character of the same name, Marvel's Enchantress has been an alias of two characters. The first of these was Amora. An arch-enemy of Thor, her various powers include mind control and teleportation. Her partner, Skurge the Executioner, was featured in 2017's "Thor: Ragnarok."

Count Nefaria

Luchino Nefaria was an Italian aristocrat-turned-organized crime boss-turned ionic humanoid. He has fought with a number of Marvel heroes. The character's daughter, the villain Madame Masque, was prominently featured in the tv series "Agent Carter."
