Grash serves as a space pirate crew member under Gail's command in "Project A-ko: Uncivil Wars." He joins Liza Chichi in kidnapping C-ko as part of Gail's scheme to use her as a host for the sorceress Xena. Their abduction attempt goes awry when Grash's ship crash-lands on a desert planet, inadvertently stranding C-ko near A-ko and B-ko. This accident forces A-ko and B-ko into action, directly setting the main plot in motion. Grash operates solely as a secondary antagonist within Gail's crew for this storyline, supporting Gail's objectives without significant character development or expanded backstory across the franchise.
