Ryuji is something of a mentor to the other Busters. Being the oldest member of the team, he is cool-headed and remains calm in most situations. He is very conscious about his age and will lash out at anyone who brings the subject up.
When overheated, Ryuji becomes sadistic and irritable, lashing out at anything that irks him. He becomes rambunctious and battle-hungry, and will generally turn against the team in some fashion.
Buster Power Program VaccineEdit
The three primary Go-Busters had program chips installed into their bodies prior to the start of the series that protected them from the dangerous effects of Meta-Viruses as well as cybernetic teleportation. This way, they could be evacuated from the site of the Messiah Incident. The Chips give each Buster a special power to use in combat, typically with a crippling trade-off each Buster must keep managed.
Ryuji is granted super-strength by the program, which allows him to deal much more physical damage and lift heavier objects than the average Human. His weakness activates whenever he over-exerts himself. Ryuji's personality is overwritten by a much darker, sadistic persona that will lash out at pretty much anything. The side-effect is temporary, but has the potential to deal permanent damage to Ryuji's body before he collapses from exhaustion.
Buddy Roid SystemEdit
Each Buster is assigned a Buddy Roid, which essentially acts as a personal support unit, an interactive console for the Buster Machines, and armor plating for Powered Custom Mode. The Roids have watched over the Busters since the Messiah Incident and as such act as surrogate parents/companions.
Ryuji is linked to the Buddy Roid Gorisaki Bannana.
