"Enemy of My Enemy" is the 20th episode of Season 1 of Teenage Mutant Ninja Turtles. It premiered on April 12th, 2013.
"A masterpiece of a modern coup d'etat."
When a Kraang invasion scheme threatens to destroy the Turtles and put the whole world in danger, Karai offers an alliance with the Turtles. After declining Karai's offer, the Turtles eventually decide that teaming up with Karai might be a good idea when Karai mentions weapons that are being shipped to the Shredder that she could steal. However, when the Turtles plan on destroying the Shredder once and for all, Karai's loyalty to the Turtles vanishes and now the Turtles must deal with Shredder and Karai, along with the Kraang.
We join the Turtles on a rooftop watching the T.C.R.I. Building. According to the data unit that they recovered, a Kraang Scout Ship is scheduled to come through the dimensional portal that night. Just then, Karai appears out of nowhere. She immediately tugs out her blade and joyfully attacks Leo. Donnie, Raph, and Mikey all join in to fight her. She mentions that she overheard Donnie talking to his brothers about the Kraang. At first, they don't want to let her in on the situation, but Raph lets slip that they are trying to stop the Kraang from causing a full-scale incursion. Suddenly, a flash of purple light comes from the T.C.R.I. building. A door opens in the side of the skyscraper and a strange craft floats out of it. It resembles a huge jellyfish, with a round body, three short, stubby 'tentacles' and a single purple "eye", which it can fire lasers from. It is piloted by two Kraang who spot the Turtles and Karai and then move in to attack. The ninjas run across the rooftops, narrowly avoiding the ship's energy beam weapon. Karai ducks into an alley while the ship continues to pursue the Turtles. Leo runs out to draw the ship's fire, while the other three make it to the sewers. Leo joins them and they watch the ship from a storm drain. The ship quickly activates a cloaking device and vanishes to avoid detection by a passing Police helicopter.
Karai returns to the Foot's headquarters and reports what she has seen to Shredder. He ignores the fact that the Kraang could put them at risk and tells her that they will soon receive a large shipment of new weapons that can put an end to their war with the Turtles and Splinter. In The Sewer Lair, the Turtles talk about how they should take the scout ship down. Donnie suggests setting up radar beacons on different rooftops on the city, and these will detect the ship, even when it's cloaked. The Turtles head out do this and, after Leo finishes setting up the last of his beacons, he turns just in time to deflect an attack from Karai. After a brief spar, she tells him that she wants to help them in fighting the Kraang. She is afraid that Shredder's stubborn refusal to see anything passed his revenge will get them all in trouble. She asks for a temporary truce, but Leo refuses and departs.
Back at the lair, he discusses the situation with his brothers and Splinter. He knows that he shouldn't be trusting her, but can't shake the feeling that she genuinely wanted to help. Splinter offers the explanation that loyalties can shift, but many Kunoichi are deceptive and cannot readily be trusted. Donnie mentions that it would be nice to have a Kunoichi on their side, accidentally insulting April. Driving through town in the Shell Raiser, Donnie detects an airborne object that doesn't match any authorized flight patterns, therefore it's the Kraang Ship. It spots them and immediately opens fire. The ship chases the van all the way down the street. Leo asks Mikey for an escape route and Mikey accidentally leads them into a back alley that's a dead end. The ship starts to blast through the rear of the Shell Raiser, but Karai suddenly appears on a motorcycle. She jumps onto the Kraang ship and plunges her blade into it's hull. The Kraang panic and retreat with her still on top of the ship. Leo decides that they must rush to her aid, but Raph disagrees. Donnie adds that the Shell Raiser cannot take another onslaught right now, so Leo uses the Stealth Bike to go after the ship. He uses a nearby car as a way to hoist himself into the air, just in time to catch Karai as she falls off of the ship. Leo activates the bike's stealth mode and the ship moves on after it fails to find it's opponents.
Leo drives the Stealth Bike underground and parks it next to the Shell Raiser, where his brothers are. He reveals to them that he brought Karai with him. Raph is less than thrilled that Karai will see all of their gear, but Leo tells his brothers to hear her out. Karai tells them that they need her help and that the only way they can take the ship down is with heavy weaponry, as opposed to the compressed garbage and manhole covers that the Turtles have. She then tells the Turtles that The Foot Clan will be receiving a shipment of weapons, among which includes a shoulder-fired missile launcher that they could use. Raph senses a trap, however, so Karai says she'll go get the launcher herself. Leo agrees to this, saying that, if she gets the weapon, the Turtles will team up with her to stop the ship. At the lair, Raph figures that, when the weapons shipment comes, Shredder will most likely be there to inspect it. For the first time, the Turtles will know where Shredder will be ahead of time and can set up a trap for him. Leo has misgivings about refusing to go along with the deal they made with Karai, but he eventually agrees.
At the wharf, Karai, Shredder and a couple Foot Soldiers meet a man with a Russian accent and a diamond eye, who is actually one of Shredder's old friends. The Foot give the man his due payment and Karai goes to inspect the merchandise. Meanwhile, just out of sight, the Turtles are preparing to have Mikey slingshot an electro-grenade at Shredder. As Karai retrieves the missile launcher, she spots the Turtles. She tackles the Shredder out of the way so that the grenade electrocutes the Foot Soldiers and the man with the diamond eye. Karai then fires the missile right at the Turtles. They manage to jump clear, but soon find themselves trapped with Shredder on one side and the newly arrived Kraang ship on the other. The turtles run between the shipping containers, with the Shredder in hot pursuit. He is eventually able to corner them and demands Splinter's location, although he offers to let the Turtles live long enough to watch their sensei's demise...However, the Kraang ship appears and opens fire. Shredder backs up into a shipping container to avoid one of the perilous blasts. As the ship flies around for another pass, Leo runs up to the container where Shredder is, closes the doors and locks them, trapping Shredder inside. Leo then runs after the ship, but the other three are caught off-guard by the Shredder as he slices his way out. Leo makes it to the box of missile launchers, but he is confronted by a livid Karai. She tells him that she feels betrayed and that he is almost as short-sighted and obsessed as Shredder. She then reveals to Leo that Shredder is her father. Leo is quite shocked by this news. Karai says that their deal is now off and attacks Leo. After a short fight, the ship returns and Karai easily hides from it. When she emerges, however, she finds that Leo has already gotten hold of an RPG and has gone after the ship. Meanwhile, Raphael, Mikey and Donnie fight a losing battle against Shredder. Leo takes aim and fires a missile directly at the ship, hitting it's mark. The hovercraft crashes into the wharf, knocking Shredder into the ocean. Karai dives in after him, while the Turtles observe this and then retreat.
Later, on the rooftops, Leo stews about how he blew their chance at getting Karai on their side. Back at the wharf, Karai helps the Shredder out of the water. He thanks her and tells her that he has found a 'pet' for her, revealing that he has abducted a Kraang.
- When Karai dove into the water Leonardo was seen with only one sword, however, in the next scene when the turtles are on the rooftop Leo suddenly has both swords with him.
