This is really new giveing Garnet some voice lines for Iron Giant. I can't wait to hear what kind of voice lines she probably has for stripe. Speaking of stripe who even has voice lines for him and does he have any voice once for other charaters too.
From what I’ve tried to find so far, Gizmo and Stripe don’t interact with anyone. Doesn’t make much sense since their language is somewhat cohesive, and subtitles do the rest of the work. But in reverse, here’s what I know so far. Harley and Marvin have Gizmo as a friend. Garnet and Giant have Gizmo as an enemy. Wonder Woman has Stripe as an enemy. You are correct, Gizmo’s enemies make no sense.
