## History

### Early Life

As a normal baby alligator, Leatherhead was raised by a kind human boy (whose name remains unknown), until his disapproving parents found out and flushed him down their bathroom toilet into the sewers. The Kraang found him, and brought him back to Dimension X, where they performed horrifying experiments on him, but, through all of it, they never broke his spirit. He escaped his captivity and returned to Earth using the Kraang's dimensional portal, at the same time stealing the Power Cell that ran it. Without this cell the Kraang cannot pass between Earth's dimension and their own, and if it were returned, they will be able to start their invasion. So, Leatherhead returned to the sewers and kept the power cell locked away for the next six months, swearing to keep it out of their reach, even at the cost of his own life.

### Season 1

***It Came From The Depths* :**When Leatherhead makes his debut in this episode, the Turtles find him in a pitched battle with a squad of Kraang. Michelangelo lead the charge to help him. Leatherhead was rendered unconscious and Mikey convinced the others to take him back to the lair. Leatherhead attacked the turtles repeatedly, but Mikey was able to befriend him and earn his trust. When the other turtles recovered the power cell and Leatherhead saw what they had obtained, he flew into a rage and attacked all of the turtles. Splinter was able to defeat him and drive him off. Mikey immediately rushed out to find him, and found Leatherhead at his own lair in an abandoned subway car. The other turtles then arrived, believing that Leatherhead had malicious intentions. However, Leatherhead pleaded with them and explained his origins. The Kraang attacked the subway car, and Leatherhead entrusted the power cell with Mikey, and faced the attacking Kraang, giving the turtles time to escape. In the end, a Kraang said they had to tell the other Kraang about the power cell but Leatherhead wouldn't let them tell anyone, anything.

***TCRI* :**The turtles seeked Leatherhead's help in retrieving the power cell after the Kraang stole it, only to find him asleep. Leatherhead awoke, only to grab Donnie by the face *again.*He snaps out of it, and the Turtles told him about losing the power cell. He flew into a fury and grabbed Donetello's face once more, before snapping out of it and giving them all of the information he posessed about the Kraang and the portal.   The Turtles then used him as a distraction to allow the gang to get to the top of the TCRI building. He fought Traag, and dragged him through the portal to give the turtles time to escape.

### Season 2

***Mazes & Mutants:*** Leatherhead appears as an illusion of a fire breathing dragon. The turtles end up defeating him by believing that their weapons are magical.

***Into Dimension X* :** Leatherhead escapes from the Kraang with a Kraang Communication Device, which he uses to message the Turtles, warning them that the Kraang have completed the Mutagen. The Kraang find him, and a fight begins, ending with Leatherhead being knocked out. The Turtles go and and save him from what looks like the Technodrome, where he's kept prisoner and tortured. He then shows them where the Kraang portals are, and helps in the battle that follows. Before the battle ends, he offers to stay in Dimension X, but Mikey kicks him through the Earth portal. At the end of the episode, he agrees to help the Turtles stop the invasion, and high fives the Turtles.

***The Invasion* :** Leatherhead saves Master Splinter from a few Kraang that had abushed the latter in the sewer. Splinter thanks the mutant alligator, and the latter asks were the Sensei's sons are. Master Splinter he doesn't know, and asks Leatherhaed to help search for them. He agrees and they split up. After the two split up, Master Splinter engages in battle with Shredder, and is almost defeated, when Leatherhead bursts through a wall and saves him. He then fights Shredder, until the villain gains the upper hand and throws him down the sewers. His fate is unknown after that.

### Season 3

***Battle for New York*:** Sometime the Kraang's invasion, Leatherhead is shown to have survived where he's later found by Jack Kurtzman, who brings him in alongside Dr. Tyler Rockwell, Slash, and Pigeon Pete to repel the Kraang invasion on New York City as the Mighty Mutanimals. He's the team's second-in-command of the group. The team makes their debut together rescuing the Turtles from the Kraang and he and Michelangelo share a heartfelt moment together.

***Clash of the Mutanimals*:** Leatherhead and the other Mutanimals attack Tiger Claw at a chemical with the Fulci Twins at the docks but he defeats them all and takes Slash and Dr Tyler Rockwell to experiment on them. Leatherhead and Pete run to the Turtles saying that Slash and Rockwell got taken by Shredder. Later in Shredder's Lair, he watches as Karai tried to break out by smashing the glass but failed and then Stockman-Flysays he made the Mind-Control Serum to use on Karai but then Shredder says to test it on Slash and Rockwell. After being bit by the worms, they break out as the Foot are running after them. They return to the Turtles but then Slash and Rockwell attack, as the Turtles and the remaining Mutanimals help them. They return to theShell Raiser which Donatello says its fixed after being destroyed by Kraang Subprime. They chase the two rogue mutanimals and set the traps that the party wagon has. Leatherhead makes a extra door to break into Shredder's lair and then attack Shredder, Stockman-Fly , Tiger Claw, Raph, Rockwell, and Slash.

### Season 4

**Journey to the Center of Mikey's Mind**: Leatherhead made a cameo in Mikey's imagination.

## Appearance

Leatherhead is a mutated alligator. He resembles a crocodilian with humanoid arms, legs, and the power to speak and reason. He is immensely large, has a long tail, sharp claws, and large mouth like all crocodilians do (long, narrow and V-shaped, teeth of upper and lower jaw showing when mouth closed). He has a tough, armored hide is extremely resistant to attacks, even from Kraang laser blasts.  He possesses a third eyelid, which all crocodilians have so that they can see underwater. This third lid locks in place whenever Leatherhead goes into a rage. He starts out with dark green scales on top and white scales on the underside. In Into Dimension X! his scakes have dulled to lighter of greenish grey on top and a more dirty cream white on the underside due to age and has a scar across his left eye.

## Personality

Despite his monstrous form and appearance, Leatherhead has a surprisingly gentle soul and doesn't really wish to hurt anyone. He suffers from severe self-loathing from a life of horrific abuse and everybody around him fears him as a monster. He also has periodic bouts of rage in which he can lose complete control of himself which befits him as he is an alligator and he has taken a lot of abuse from the Kraang. When he awakens later, he is always contrite and regretful for the things he has done. Because of his horrific treatment by them, he has an everlasting hatred for the Kraang and simply hearing the word "Kraang" will throw him into a rage. So far, only Mikey has been able to calm him from these rages. Leatherhead has established a lair for himself in an abandoned subway car, where he keeps his few belongings; a stuffed crocodile, a record player with an old jazz record that he uses to calm his rage, and the Kraang power cell which he guards with his own life. He has proven to be a very strong ally to the Turtles, even saving them from Traag by throwing the rock monster and himself into the portal to Dimension X.

## Bio

Uncontrollable and fearless, Leatherhead is The Kraang's worst enemy and creation. After being mutated from a reptile into a living monster, he promised himself to spare the world from their evil and captured their power cell. A powerful ally in the Turtles's fight against the Kraang, Leatherhead's raw power and brute strength make him a force to reckon with!

## Powers and Abilities

**Death Roll:**He uses an alligator move in combat where he rolls along the ground and able to crush his opponents with his weight and sharp back plates.

**Nictating Membrane:**He possesses a third eyelid, which all alligators and relatives have so that they can see underwater. This third lid locks in place whenever Leatherhead goes into a rage.

**Laser-Proof Hide:**His tough, armored hide is almost unpenetrable to Kraangdroid blasts but it is shown that it still hurts.

**Enhanced Strength:**He is an extremely powerful fighter, even defeating all four turtles in combat, beating Traag and brutally injuring Shredder. Though even with his large size and amazing strength he lost in a short, but brutal fight against the The Shredder. And his jaws can rend steel.

**Unbreakable Willpower:**He seems to have an unbreakable amount of willpower, as he would never give into the Kraang no matter what they did.

**Spiritual Rage:**Like Raph, Leatherhead has a high temper which can be used to make him stronger, in the right way, but it can leave devastating results as it causes him to go into an uncontrollable amount of rage, endangering anyone, even those he cares about.

**Weaponry:**He's immensely large, powerful long tail, sharp claws, armor body and crushing jaws to be full effect in combat with his sharp teeth.

Like the majority of the mutants, he has the powers to speak and reason. Despite his long snout, he is actually able to speak quite eloquently, though his voice is very deep and gravelly. He still able to make noises of aligator such as his hiss, growl, bellow and roar.

**Stamina and** **Endurance:**His armor body is endurable to saved the Turtles from Traag and was able to take some of the attacks from Shredder. He was one of a few, who stood a chance against Shredder and even almost defeated him. Only with his blades and agility and knowledge of pressure points, Shredder was able to bring him down.
