"Arms Race with Legs" is the thirty-first episode of Season 3 of Teen Titans Go! and the one hundred and thirty-fifth episode overall. It first aired on 5 May 2016 on Cartoon Network.


When her teammates turn evil, it's up to Lady Legasus and Firebun to stop the League of Legs.[1]


While the rest of the Teen Titans gather at the couch, Beast Boy stretches in front of them and explains to Raven that he plans to jump and touch the door jam to show how cool he is. Ann disagrees with him, but after he jumps, he impresses Cyborg, Starfire and Robin. They each take turns jumping and touching the door jam and Raven tells them to stop as it isn't cool. Beast Boy refuses and he, Cyborg, Starfire and Robin spend the rest of the day jumping and touching objects. Back at the living room, Robin challenges them to jump and touch the ceiling light. Starfire, Beast Boy, and Cyborg tell him he won't be able to, but Robin jumps and touches the light. Cyborg demands an explanation and Robin claims it's because of his tight butt. Raven appears and tells them that jumping is because of legs, but Robin laughs and challenges he to prove it. Raven declines, claiming that the power of legs isn't to be used for fun and games. The other Titans begin making fun of the two and Raven transforms into Lady Legasus in order to hit the ceiling fan higher than Robin. Ann also transforms into Firebun to do the same.

Jump & Touch

The League of Legs jump and touch.

Starfire says that they wish to leg jump like Firebun and Lady Legasus but they refuse, claiming that leg power can be intoxicating and lead to bad things if unchecked. After Beast Boy flatters her legs and the Titans encourage her to change her mind, Lady Legasus agrees to a little fun. Cyborg transforms into Thunder Thighs, Starfire becomes the Incredible Quad, Beast Boy turns into the Calf, and Robin changes into Captain Cankle, reforming the League of Legs. The League of Legs jump around Jump City, touching various objects and Batman. At night, the League of Legs overlook Jump City on a cliff and Lady Legasus tells the League that their legs have to be put away, much to Firebun's joy.

The next day, Raven and Ann notice that the Titans haven't abandoned their League of Legs personas and are using their legs for menial tasks. The Incredible Quad says they attempted to put the legs away, but the legs refused. Raven claims that because they're using their legs improperly, their legs are taking control of them. Captain Cankle, Thunder Thighs and the Incredible Quad claim that they're following Raven's example as she used her legs improperly to prove Robin wrong and enjoyed jumping around town with them. Raven is unable to make an excuse, but begs them to stop. The Calf challenges her to and the four jump through the roof and onto the ceiling. Raven follows and sees them hitting an eagle, breaking a rainbow, slapping a cloud, and knocking down an airplane. The two transform into Firebun and Lady Legasus and uses her legs to save the plane.

Lady Legasus is forced to become Raven

The League of Legs force Lady Legasus to become Raven.

Lady Legasus orders the League of Legs to disband, but Captain Cankle challenges her to a contest between them. If Lady Legasus wins, they'll disband, but if Captain Cankle wins, she must leave the League. Lady Legasus refuses, but they begin making fun of her. She accepts and Captain Cankle wishes her luck as he has a leg up the competition. He shoots into space and slap an astronaut's butt, but when Lady Legasus tries, she fails. Lady Legasus is shocked that her legs failed her and warns the League that their legs are becoming evil. Captain Cankle reminds her of their deal and she reluctantly becomes Raven again, causing Firebun to cry. The League resume jumping and touching in Jump City, but start breaking everything they touch.

Mega Legasus defeats League of Legs

Raven becomes Mega Legasus and defeats the League of Legs.

Raven and Ann, now with a slightly terrible face, observe from the Titans Tower and throws her leotard in frustration when weights roll out. They realize that the League rigged the challenge and transforms into Firebun and Lady Legasus. The duo confront the League of Legs in front of the ruins of Jump City Museum, but they're easily defeated. Captain Cankle tells the girls to join them or face the consequences, but Lady Legasus and Firebun call upon the ancient spirit of fire and legs and fire and transform into Mega Legasus and Megaburn. The League of Legs lock legs and attack with Leg Lock, but Mega Legasus and Megaburn break their formation and attacks the members individually, breaking their legs. Robin, Cyborg, Starfire, and Beast Boy apologize for their mistreatment of legs and thank Mega Legasus for stopping them. Robin says he'll never use his legs again, but Mega Legasus reassures that he'll earn the right to become Captain Cankle again. Robin clarifies that he won't be able to use his legs again, because they're broken badly. Meanwhile, Ann walks up to Starfire and yells that she is banned from the Girlygroup for 30 weeks.
