Ridley is a minor character/boss in Abobo's Big Adventure.
Ridley is a boss and member of the space pirates that originates from the NES game "Metroid." He is also the secondary antagonist of the series.
Ridley is only seen flying in the air in the game's opening sequence, on the screen where he flies below the Statue of Liberty next to Bub, who is in a bubble, and the Mecha Dragon. Oddly, he is green instead of purple.
