Adam is a recurring boss in the Cho Aniki series, first appearing as the very first boss in Ai Cho Aniki.
A obvious parody of Michelangelo's The Creation of Adam painting, Adam is a giant naked man flying on a bathtub shaped like a half-moon. Inside the bathtub are various smaller buff guys who help him fight and also a woman. Adam can fire homing shots from his pointer finger, swing his leg to spread shots, or use his bathtub as a shield or to fire missiles.
Adam appears as one of the playable characters in Cho Aniki Bakuretsu Rantouden and as a NPC in Cho Aniki Otoko no Tamafuda.
