Jack is a merc and mech pilot. Jack is a brash, young individual who aspires to uproot legendary mercenaries and become the greatest mercenary alive. His mech, Flame Fly, is a low-cost, non-threatening unit known for its bright red coloration, distinct emblem and its overall low armor. Flame Fly is a midweight, biped mech constructed completely from the cheapest parts available: Junk. It's terrible at what it does, but Jack doesn't care, and brushes off any insults or remarks.
