Gigiras (ギギラス) is a Soul used by Phobos Quasar.
It first debuted in episode 41, used by Phobos to stop Ookami's Soul Strike and later to stop Scream of Eden. Both attempts were successful.
The user turns into Gigiras and flips its two front tentacles to stop the shoot. If it succeeds, the ball will be slammed to the ground.
