Gyrus is a young engineer and astronaut from 2545 A.D. He has several diffrent versions of himself which all display distinct diffrences from one another while still being the same person. Note: The following contains spoliers for Room of Swords

The younger version of Gyrus, which the comic follows as our main protagonist, is bright and curious. He's generally well liked by others, and is able to befriend people easily. Romantic cues go over his head completely- especially so with Tori. He's naive, yet incredibly intelligent, and cares deeply for others. He's slow to anger, but quick to beccome emotional (it's easy to make him cry.)

Black Box Gyrus, or BBGyrus, is a manifestation of the concious of Past Gyrus who resides in the Black Box. He is much less emotionally vunerable than Gyrus- he's often refered to as "edgy" by readers. He is dramatic and serious, only really showing the lighter side of his personality when interacting with Kodya (mainly through flirting.) BBGyrus is much quicker to anger than Gyrus, and less likely to cry or become emotional. 

Past Gyrus is the version of Gyrus that BBGyrus is a manifestation of. Past Gyrus cares about others and has a desire to help and protect, often at the expense of his own saftey. He's emotionally closed off while still putting up a cheerful facade to others to hide his internal conflicts. The only person he is emotionally vunerable with is Kodya. He displays strong emotions at times, as well as paranoia and fear. 

The following contains MAJOR spoilers for Room of Swords. It's highly recomended that you've read up to season 3 before auditioning for this role. 

Masiosare is an emotionless, apathtic version of Gyrus from the future. He is willing to sacrifice whatever it takes to acheive his goals, going so far as to commit murder. He has no emotional connection to anyone and is soley concerned with accomplishing his goals. Anger is the only real emotion he displays at any point- he completely stoic the rest of the time.
