E2 Jet, a Hikarian defined by an insatiable obsession with speed, compulsively races against faster entities even mid-mission, prioritizing velocity over protocol. This recklessness draws disciplinary lightning strikes from Professor 300X and culminates in suspension, though records indicate eventual correction of this behavior. In battle, E2 Jet assumes a supersonic robot form, wielding a jet gun for precise, high-impact strikes. His signature jet gun attack merges breakneck agility with calculated targeting. Though singularly driven by velocity, he demonstrates fierce loyalty to allies, often pivoting from combat to extract endangered comrades during crises. A namesake counterpart appears in the sequel *Ultra Radiant Express Hikarian*, explicitly established as a separate entity. Available documentation confirms no direct references to this iteration’s presence in OVAs, films, or spin-off narratives.
