Static Jack

Static Jack is the owner of Static Jack's Diner. He is also the last surviving member of The Surreal Seven, whom he fought with prior to their breakup. Jack was seemingly eager to reunite the Seven, referring to Mat as an "old friend." Jack left his diner, travelled with Mat to collect Tetrad, and then came to rescue Melon and Kazeus' aid at the Mustard Mansion. After this, he travelled to Earth and began preparing for battle.

Jack witnessed Mat's lie to Kazeus in the war room.

When Alabama arrived, Jack was stationed by the Lil Sooch memorial with Tetrad. Upon the Qyüb's assault, Jack flew into the air and began destroying Elon's rockets with his static abilities. Jack was in the atmosphere when Earth exploded, allowing him to survive.

In Void Manifesto, Pt. II, Jack was shown to have returned to the diner and hired Sexy Boy as a cook. When Mat desired help in killing The Green Ball, Jack scolded him for allowing so many to die. He rejected Mat and begged Melon to do the same. Melon refused and followed Mat to Sector 9ine.

When Melon finally did return to the diner, Jack inquired as to what had happened between him and Mat. Melon presumably told him. Jack was last seen watching the fight between his former comrades Mat and GB.
