Arseny Lysowsky

Arzeny Lyswosky is a Russian crime boss that appears in Season Two of Criminal Minds.

Background
In Russia, Lysowsky spent years in 23 remote prisons, gaining tattoos and joining the Russian Mob, eventually becoming the Pakhan. At some point in his life, he met Katya and had a son, Lyov. While Lyov eventually grew to forsake the codes of the Russian mafia, Arzeny would remain true; even going against his own son when Lyov's exploits became dangerous to the family.

Honor Among Thieves
Arzeny first appears to offer help to Natalya Chernus, breaking her father out from Lyov's hands. But, since she is actually allied with Lyov, she refuses, making Arzney look like the villain. He later pays the ransom despite what Natalya says. Arzeny is visited at his "headquarters" by the BAU. Gideon attempts to get information about Lyov's abduction ring, but Arzeny informs him that FBI interference is unnecessary, saying, "We take care of our own." Meanwhile, at the kidnappers' hideout, Lyov attempts to kill Mr. Chernus, but Arzeny's men arrive and kill Lyov and Natalya, dumping their dismembered and bagged bodies from a bridge.
