From Spider-Man to the X-Men, the heroes of Marvel Comics must deal with their fair share of nefarious teams who have united to destroy them. These are the most underrated supervillain organizations that deserve more recognition.
5) Lethal Legion

Much like the Masters of Evil, the Lethal Legion came together for the sole purpose of destroying the Avengers. The original team was assembled by the villain Grim Reaper, who sought revenge against the Avengers for the role they played in the death of his brother, Wonder Man. Since then, different incarnations of the Lethal Legion were founded by Count Nefaria, the Grandmaster, and Satannish. This alliance of evildoers has come close to wiping out the Avengers on multiple occasions. The strongest members have included Living Laser, Grey Gargoyle, Goliath, Sabretooth, Thundra, and Whirlwind. As long as the Avengers exists, a new Lethal Legion should emerge to combat them.
4) S-Men

A team of villains who are the antithesis of the X-Menโs mission of fighting for mutant rights, the S-Men were created for the sole purpose of wiping out mutantkind. Created by the Red Skull, the rest of the S-Menโs roster were all victims of crimes committed by mutants. To level the playing field, Red Skull used science and magic to give each of his S-Men superpowers. The other members of the S-Men included Dancing Water, Insect, Living Wind, and Dangerous Jinn. As for Red Skull himself, he stole Professor Xโs corpse and used it to give himself telepathic powers. The S-Men were the most fearsome threat the Avengers Unity Division faced and stoked the fires of hate against mutantkind.
