[Orange Duke]

Yes. You'll notice that in the fic he used an ability to split Star Caster into a bow. He's the sole owner of a new (okay, maybe not new considering it has been thousands of years since its inception) system called the Universal Weapon System, or UWS for short, that goes on the forearm, the result of months of dedicated research with his legion prior to his retirement from Brain Burst. It was originally made for mass production to revolutionize the way Linkers fight, but he left Vise to oversee its mass production before retiring. Vise had always secretly hated everything the Orange King stood for and this hate clouded Vise's judgement. To Vise, the UWS represented the Orange King's hopes and dreams for the future. As a result, before any mass production could start, he (quite foolishly) destroyed the blueprints for the UWS and had all of the researchers involved executed, thereby rendering the blueprints permanently lost.

Equipping the UWS grants the user 2 additional weapon slots, 1 for a firearm and another for a melee weapon. Both slots are on an axis joint, allowing the user to change from close-range to long range instantly. That's not where its versatility ends, however. Certain melee weapons unlock new weapon types, though this is really dependent on your creativity. For example, equipping a sword offers you the option to use up your special gauge and split it in half to form a bow. Alternatively, you can unlock the swivel joint and allow it to spin freely, effectively forming a chainsaw that can act as a shield. An interesting thing to note is that the Orange King wears his UWS on his left forearm, thus betraying the fact that he is a southpaw.

Orange is supposed to convey a sense of freedom and versatility and that was how I felt it best represented, along with the Indirect and Long-range properties it entails.

Nothing is set in stone, though. If you have any suggestions as to how to balance it better if you feel that it's too OP, do let me know.

EDIT: Left out the abilities his Avatar was born with. He suffers from mild split personality disorder in real life. As a byproduct, he is able to split into a Red avatar and a Yellow avatar, each with their own specialties. It's not used often though. Doing so would risk aggravating his condition, and upon splitting it's extremely difficult for them to render as a whole again.
