Rhino Wrestler

Rhino Wrestler (サイレスラー, Sai Resurā) is a Mysterious Being belonging to the Monster Association who first appears during the attack in S-City.

Appearance
Rhino Wrestler is humanoid with various characteristics associated with a rhinoceros. He has a face which is that of a rhino and is heavily built, with many layers of thick skin and armor on his body. He wears a wrestling singlet and has an armband on each arm. On his abdomen is a large tattoo.

Personality
Rhino Wrestler is very prideful and eager to put his strength to the test. In addition, he desires to be praised by others. A testament to this can be seen when he asks Phoenix Man what he thinks of his disaster level.

Like most other prideful monsters, he doesn't care about compatibility with other heroes, with his only style of fighting being knocking down whoever comes in his way.

Unlike most of the other monsters, Rhino Wrestler actually trains to hone his fighting abilities.

Monster Raid Arc
Rhino Wrestler, Phoenix Man, and Sludge Jellyfish stop Mohican and Pineapple when the two heroes were trying to leave the city. Rhino Wrestler is left to the heroes by himself while the other monsters scout around. Rhino Wrestler is utterly bored by his opponents' pathetic attacks and decides to rate their attacks and scores all of them very lowly.

After his rant about the heroes' strength, Rhino Wrestler boasts about his training towards his opponents and expresses his utter disappointment in the heroes that he is facing. Phoenix Man alerts Rhino Wrestler that it is time to leave and to take the hostages. In addition, he reminds Rhino Wrestler that today is not the "main event", so they can't do as they please. Finally, Rhino Wrestler is told to only take the son of the Hero Association sponsor. Mohican and Pineapple make a final desperate attempt to stop Rhino Wrestler, but fail miserably as Rhino Wrestler is able to easily charge through them. Afterwards, Elder Centipede grabs Phoenix Man and Rhino Wrestler and leaves in the hole he created earlier.

Monster Association Arc
In the Monster Association, Maiko Plasma, Electric Catfish Man, and a few other monsters are discussing amongst themselves, while Wrestling Rhino is training. The other monsters are impressed by the victory Maiko Plasma and Electric Catfish Man had over Lightning Genji. The pair of monsters states that Gyoro Gyoro was the one who ordered them to fight Lightning Genji, and that as long as the monsters fight who Gyoro Gyoro tells them to fight, they won't lose. Rhino Wrestler interjects and states compatibility as "Such bullshit". He boasts that he will knock down whoever comes in his way, and completely destroys the punching bag he was using to train, reveling in the knowledge he will soon prove his strength.
