Light Serpent (ライトサーペント Raito Sāpento in Japanese) is a Magic Lifeform and one of Medusa Gorgon's attacks, in which she uses the snake Magic Lifeforms that are attached to her arms in the form of tattoos. She sends one of the snakes shooting forward in order to bite the opponent. Because Light Serpents respond to simple directions but are not as fast as with her Vector Arrows, Medusa tends to use them when she is immobilized or otherwise unable to perform complex magic. For example, to remove the Soul Thread Sutures that Franken Stein used to pin her to a wall, Medusa released Light Serpent.
