Zegga

"I can't make kaiju anymore..."
"I think you misunderstand me. I'm fine with you becoming a kaiju yourself. Instance...Abreaction!"

―Alexis turning Akane into a kaiju

Zegga (ゼッガー, Zeggā)^[1] is a kaiju created by Alexis・Kerib using his Instance Abreaction on Akane Shinjo.

History

SSSS.GRIDMAN

Seeing that Akane refused to create any more kaiju, Alexis decided to instead turn her into one, saying that someone who makes kaiju is a kaiju themselves. Within it, Akane was haunted by her grief and the victims of her past kaiju. As Zegga rampaged through town, Gridman/Yuta asked Anti to deal with it while he regrouped his friends for the final battle. After a short struggle between Zegga and Gridknight, Anti opened up its mouth and jumped into the 'face' inside, where he managed to pull Akane out of it, though he was impaled by Alexis immediately after. Zegga sat lifeless and then rolled around aimlessly, before it was erased by Gridman's Grid Fixer Beam.^{Awakening (Finale)}

Trivia

Designer: Mahiro Maeda
Zegga's design is actually recycled from a scrapped concept art of Khan Digifier's invasion tentacle from the final episode of Denkou Choujin Gridman.
Since Zegga's roar is derived from Akane screaming "No!" upon Alexis using his Instance Abreaction, Zegga's roar is altered in the Funimation dub to reflect that.
