The vitriolic Viacheslav Datsik has written to the Moscow City Court requesting them to not release Aleks Emelianenko, the younger sibling of Fedor and fearsome MMA fighter in his own right.

Datsik, who once described himself as “too raw for humanity”, was also a MMA fighter. He gained notoriety in 1999 after knocking out present UFC heavyweight contender Andrei Arlovski in what was both of their debut bouts.

The self-styled “Red Tarzan” is currently serving time in a St. Petersburg prison himself, following a number of offences ranging from armed robbery to escaping the psychiatric ward he was sentenced to after the courts recognized him as insane.

His escape from the low-security mental hospital led him to cross into the Norway border from Leningrad before proudly declaring himself as “not a nationalist, but a racist” to the journalists present. Datsik has not been secretive of his beliefs, having made various anti-Semitic and anti-Christian views public—including the claims that Jesus Christ was a Mossad agent.

If you still had any doubts about Datsik’s mental faculty, check out his “highlights” below.

Emelianenko is no angel himself, having been sentenced to prison for four-and-a-half years in May 2015 after being found guilty of rape. Aleks also has some questionable Russian prison tattoos some have accused as promoting potential Neo Nazi beliefs.

The diabolic Datsik sent his page-long diatribe to the Moscow courts. This included the following rambled passage: “I have known Aleks since 2003. Initially it was sport and friendship. But, I did not recognise his vile and rotten nature. This man is prone to betrayal and deception to profit from his friends and acquaintances.” This is before he accuses Fedor’s sibling of beating women at sporting events.

However, the two were supposedly friends at one point in time according to Datsik. In 2010, Emelianenko refuted this, saying: “This man isn’t a normal person. People like him shouldn’t be around normal people. He should be kept separate from society.”

To that, Datsik then publicly asked—from a prison cell, of course—to have Emelinaneko’s address so he can come find and confront him once he eventually gets his release from prison. If that ever happens, anyway.

It is highly doubtful that Datsik’s plea to the courts will see the time of day. But, this is the latest incident in one of the strangest and longest-running rivalries MMA has to offer.
