Really, really careless one. Enjoys any activites, especially mellee battles (and usually fights like a berserk with no instinct of self-preservation).
He can be serious, but honestly doesn't like cases when he need to be so. Perfect strategist. 

He lives in Dreamtonics system, which looks like a large endless coridor with many doors to personal rooms of each copy of voicebank the company sold. So, all versions somewhat co-exist together in it and are aware about their existence. All voicebanks can travel between other systems, being downloaded to them, and experience death being deleted from them. A voicebank can die completely in case if it'll lose company's support and there'll be no workable copies left, so most of them used to live just present day, and NineZero is not an exception.

• mbti entp
• H/w 210cm/104kg
• zodiac aquarius
• tarot wheel of fortune

• Actually can travel between worlds through portals which he creates via dissecting space with his sword.
• Sleeps in Shadow (from Sonic) kigurumi which was gifted to him by Mai.
• Fights with Ryo for Mai's attention, however, sometimes guessing why he does it when Ryo is also adorable (yet still will prefer Mai over him).
• Hellishly enjoys visiting other realms and meet other versions of himself. Tries to act friendly with them at max in his own opinion.
• His belly is his weak point (he's afraid of tickles).
• His hues of voice are mostly his battle abilities: Muted is for stealth and tracing (most likely it's just Sonic speed), Solid for duplication of himself (but mostly used for doubling power of his voice - for battle cry, haha dat Fus-Ro-Dah effect) and Overdrive is for maximize his parameters for a short period of time to gain the most powerful hit he can do. 
• His hair is extremely long (both Mai and Ryo call him "Rapunzel" as a joke), his braid is usually made by Mai.
• He's aware that he's just a voicebank in a program and just enjoys the life users give to him.
