Rocksteady

After Mutation

Before Mutation

**Ivan Steranko** was a Russian arms dealer who was mutated into an anthropomorphic rhinoceros, now going by "**Rocksteady**". He is frequently paired with Anton Zeck, a.k.a. Bebop, who he had previously done business with.

The rap sheet in prison guard Casey Jones' hand lists Rocksteady's name as Ivan Steranko. Rocksteady and Bebop were originally two criminals being transported at the same time as the Shredder. They provide assistance in Shredder's rescue and escape themselves; in return, Shredder hires them as "errand boys." He selected the pair to be test subjects for a new variation of the Mutagen which taps into dormant animal DNA in their system from a point before life on Earth began to evolve in different routes, causing them to mutate into their familiar states. After Baxter Stockman initiates the procedure, Rocksteady becomes a humanoid mutant white rhinoceros.

## Personality

He describes himself and the Shredder as "old friends." He seems to take great pride in his collection. Steranko is rude and humorless, but is willing to be reasonable and make deals when the opportunity presents itself.

As Rocksteady, he is even more aggressive and develops more fighting skills to match his new form. He even likes the name Michelangelo gave him.

## Powers and Abilities

### Powers

* **White rhinoceros physiology:** As a result of his mutation, Rocksteady gained the body of an anthropomorphic white rhino. As such, he has the natural abilities of a white rhino.
	+ **Enhanced strength:** Rocksteady's strength has been enhanced to the point where he is able to lift someone up with just one arm. He is strong enough to lift a grown man up with just one hand and easily overpower Hulk, who is also a capable hand to hand fighter.
	+ **Enhanced speed:** Rocksteady has claimed that his mutation increased his speed and he was able to catch up to Leonard, Michelangelo, and Raphael while they were on a roller coaster.
	+ **Enhanced endurance:** Rocksteady has the same level of endurance as a rhino. One such example of this is when he handled being blasted by a Kraang security blaster without showing any indication of being harmed.
	+ **Jagged horn:** Rocksteady's mutation caused him to have the jagged horn of a rhino, which he can use for offense.

### Abilities

* **Marksmanship** Rocksteady is proficient in using energy blasters despite only having one eye.
* **Skilled Combatant:** Rocksteady is a dangerous and skilled fighter. Despite only being human, Steranko is shown to be frighteningly skilled, both in hand to hand combat and weaponry, proving to be a lethal individual.
