Gagagigo is a character version of the card, "Gagagigo".
In the OCG/TCG, Gagagigo's card illustration history depicts him as a tragic character, who grows up to be evil but has a change of heart after meeting and being saved by Marauding Captain. He goes on to fight many battles, but loses himself due to body reconstruction and rampages mindlessly. However, he ultimately recovers his senses and turns good again.
In the manga, Gagagigo appeared as an Egyptian monster spirit.
