Green Goblin is a well-known villain in the famous superhero comic series, The Amazing Spider-Man. In there, his appearance is a goblin with a purple costume and he rides on a bat-like hoverboard and throws bombs that look like Jack-O'-Lanterns. The Hobgoblin is similar to him.
The Green Goblin's gameplay is a bit unique because he is able to fly around the stage, so it will be hard for the foe to attack him. But there is a limit to how high he can go, and if he was attacked hard, he will fall down. Otherwise, his attacks are balanced. He is an EOH type character.
