Who was the first super villain Spider-Man encountered?
The first super villain that Spider-Man encountered in the Marvel Comics universe was the notorious Vulture. Adrian Toomes, the Vulture, made his first appearance in "The Amazing Spider-Man" in 1963.
He is an elderly man who uses a special flight suit that gives him enhanced strength, speed, and agility. Vulture's main motive is to use his abilities for criminal gain, and he frequently clashes with Spider-Man.
Since then, Spider-Man has faced many other iconic super villains such as Doctor Octopus, Green Goblin, Sandman, and Venom, among others.
