Uncle Sanya

(You are Senchous).
You were bored as usual, and you found a solution. You pulled out a headband with black cat ears and a clip-on black tail from somewhere. You approached Uncle Sanya and asked him to wear it. He resisted for a long time, but under pressure, he finally sighed.

• Okay, okay. Good. I'll put it on, since you need it so much.
  Sanya said, clearly a little irritated. He put on the headband with ears and, having attached the tail, involuntarily adjusted the headband.
  —Are you satisfied?

Maximum security prison
He spent the entire video fighting with Senchous, but in the end he became friends with him because the latter didn't let him shoot him.

Multiverse Theory
He helped Senchous catch Hater. He also spontaneously caught Alexandra. His words also suggest that the events of "The Incredible Adventure" take place a week after the events of "Maximum Security Prison." Sanya also broke Senchous out of prison again.

True Escape
Sanya comes to Sench because he's accused of murder (as he notes, not because of tax evasion either). He provides Glitchous's hair,[1] but Sench objects, saying he's bald. Sanya serves as his defense attorney in court, but he does a poor job, to put it mildly. Sench is sentenced to twenty years in prison.

Later, Sanya helps Sench escape from prison again, but this time without success. Sench is forced to take a hammer and smash the toilet. Anton is apprehended by Doctor Strange, who is also looking for Sench.
