A member of the Teen Titans in Teen Titans Go!.
Beast Boy is Cyborg's best bud - a slightly dim but loveable loafer who transforms into all sorts of animals when he's not eating burritos and watching TV. He's mostly a vegetarian but respects a balanced diet. Lacking any redeemable qualities, Beast Boy still attempted to romance Raven when Cyborg revealed they were compatible according to his glitched love matching program. He later fought with Starfire over a scratching post. Beast Boy fell in love with the villainous Terra and was ignorant of her intention to destroy the Teen Titans.
Beast Boy was sure there was good in Terra despite her utter hatred for him. Upon learning Terra was banished in a dimension reserved for the Titans' trash, he tricked Raven into opening a portal and threw down a rope for Terra. After freeing her from banishment to another dimension, helping break into a restricted warehouse, and serenading her, Beast Boy appeared to have gotten through to her but Raven dumped her into the same dimension with Beast Boy in tow. Beast Boy later attempted to make himself smarter but when that failed, he turned to Raven's book of spells but failed at that, making Silkie super smart and the other Titans dumb. He later posed as the supervillain Beast Bob to join H.I.V.E. and get some pizza.
During a battle against Cinderblock, Beast Boy suffered a horrifying injury. One of Cinderblock's fists was lodged in his face. Robin managed to remove the fist but Beast Boy was scarred. His head was bandaged up for six weeks then another six weeks. The Titans discovered Beast Boy had a scar through one of his eyes. Cyborg tried to assure him the scar made him look tough. Beast Boy bought into it but took it too far. In a battle against Dr. Light, Beast Boy purposefully raised his left hand into a light beam and let it get blown off. Cyborg attached a robotic implant while he tried to figure out how to reattach the hand, kept alive by Beast Boy's animal powers. Beast Boy declared he was a man and took the name "Scar Man." The next day, Scar Man replaced all but his head with robot parts. He refused to go back to normal but realized the error of his ways when Cyborg replaced several of his body parts with Beast Boy's.
During a battle against the Walker Monster, Beast Boy realized he couldn't transform anymore. The comforts of modern society had stripped him of the animal instinct needed to use his ability. Beast Boy went off to get back in touch with nature. However, the wild animals and elements were brutal. After three weeks, he was starving and at wit's end. While chasing a rabbit, he met Mother Nature. While having a debate about the circle of life, Beast Boy won by mentioning tacos. He convinced her to transform part of the forest into a city for nature to live in and have tacos. After Beast Boy ate a taco, his powers returned. But while in the form of a butterfly, Robin ate him for pure protein.
Robin tried to teach the other Titans how to respect money but Beast Boy believed it was the root of all evil. He tore up Robin's $1 leading Robin to decline paying everyone. Beast Boy decided to use bees as currency and became an overnight sensation. He ignored all the bee stings along the way. Robin eventually came around and asked Beast Boy for a loan. He obliged Robin but asked for an embarrassing dance first. Beast Boy became power hungry and went into a tirade. He was stung multiple times and suffered an allergic reaction. Robin thought it was evil swelling in him and beat him repeatedly with his bo staff. Beast Boy recovered in the hospital.
During a game of Random Animal Rally, Beast Boy misinterpreted Cyborg and transformed into a man. Even he was surprised he could do that but Robin mused technically man is an animal. The Titans soon came up with a scheme to use Beast Boy to help them get into the mature rated Death Toilet 3 movie at Jump City Cinemas 12. Beast Boy then took them to eat a ton of pizza on credit, rent an exotic car, and get tattoos at the Tat Cat Tattoo parlor. After the Titans returned to the tower to turn in, Beast Boy decided to go back out and party alone. He fell prey to the mind control of The Man. The next morning, he ordered the Titans to finish their chores before he came back from work. The Titans followed him and tried to get him fired with a bad cartoon drawing of The Man but being fired was a literal punishment. When the Titans overloaded The Man with annoying teenage antics like inane conversations, loud music and teen magazines. Beast Boy was back to normal.
After a victorious battle against Slade, the Titans decided to throw a party and celebrate. Beast Boy and Cyborg remembered their childhood and recalled how clowns were so cool. They ignored Robin and Raven's warnings. The clown that came to entertain, Honk, wasn't cool at all to them. Cyborg and Beast Boy took it upon themselves to make him cool with science. After dunking Honk in their Xtreme-ification Chamber, they considered it a success but instead they just created a supervillain. While going through his room, Beast Boy found a trunk of mementos he collected from missions over the years. One was a shard of the Mysterious Prism. Keen on splitting Raven up and making out with her passionate side, Beast Boy tried to use the shard but Robin got his own idea. He used the shard to split the other Titans into their core five personalities and recruited the best one to join his elite team. All the Beast Boys were essentially the same so Robin and Soldier Cyborg elected to use one as a human shield. During the brief stint of the League of Legs, Beast Boy went by The Calf.
The Teen Titans, after being let down that they cannot watch a Rated +45 movie at the local theater, return back to the Titans Tower where Cyborg decided they can play something "stupid" to take their minds off of things. Beast Boy ends up eagerly volunteering to play "Random Animal Rally" which involves Beast Boy turning into random animals suggested by his friends. In the heat of enjoyment, after transforming into several different species of animals, Cyborg accidentally says the word "man", which Beast Boy listens and transforms into.
Cyborg becomes aghast with Beast Boy's new form, with Beast Boy himself finding the situation to be funny. Beast Boy laughs at his own reflection. Despite being poked fun at by Cyborg, Starfire, and Raven, Robin realizes that Beast Boy's new form will allow the team to take them all to the movie theaters, and they can now enter the +45-rated movie they couldn't get into before.
At the movie theaters, with smiling Titans in toe, Beast Man approaches the ticket booth deepening his voice to sound more like a "man" requesting the staff member for tickets to the "Death Toilet 3". Without any trouble, the tickets for all five of the friends are easily given out, with a happy Beast Man grabbing them and running to the movie with his friends. Later, inside the theater, the movie comes to an end with satisfied titans and a Beast Man. The friends come to consider that being an adult isn't too bad after all, and with Beast Man around, they can explore what other possibilities they can get away with.
The Teen Titans head into town to do their crazy activities and they first run into a pizza-truck, where Beast Man was easily able to pay a lot of pizzas, thanks to his credit cards. Next, they all go to rent a car. Thanks to Beast Man again, he is able to do it with the help of his driver's license. Following that, they all go to a tattoo shop and all receive tattoos on their bodies. The titans finally call it a night and return back home at the tower, where Beast Man comments how awesome the night was. Raven warns Beast Man again about changing back to his youthful-self before the "man" comes and finds him and forces him to get a job. Cyborg and Robin don't think a job would be too bad, as everything so far with Beast Man ended up being fun. With that said, Starfire announces she will be heading to bed and wishes everyone goodnight, meanwhile, Beast Man has other plans and says he'll be staying up all night going out doing grown up stuff.
The next day, Starfire finds an extremely tired and messy Beast Man out in the kitchen, where she offers some of her sugary cereal to him. He declines, saying it has too many calories and how he needs to watch his weight. The other Titans come into the kitchen, shocked to see Beast Boy is still an adult, and questions him why he hasn't changed back yet. Beast Boy shocks them again, saying "someone around here has to make a living", where just then his watched goes off and how he is late for work and gets ready to leave. Cyborg calmly suggests for Beast Boy to change back to himself, where Beast Man snaps and denies that he won't and how his "kids" better have all their chores done by the time he gets home from work. Once Beast Man leaves, Raven comments that Beast Boy has gone to the "dad" side and the "man" must of gotten to him when he was out last night. Robin taking in what Raven says, says they better follow him. The younger Titans end up following Beast Man at a office building, in line with other very similar adults waiting to be let inside. The Titans end up sneaking inside the facility disguising themselves as an adult in work clothes.
Once they got in safely, they find out that Beast Man is being mind controlled by The Man. Beast Man's friends devise a plan to get him fired, so he can be free from The Man's control, which ends up being a mean drawing of The Man snuck into Beast Man's work pile. The Man sorts through Beast Boy's work and locates the drawing as an error. The Man confronts Beast Man on his mistake and says he will have to fire him, only ironically to be actual fire burning him. Before that can happen, the Titans intervene and reveal they are in the building and engage in battle with The Man himself. Using his technology, the Man was able to create some office objects to come to life, and proceed to attack the Titans. The Titans end up redrawing, and taking Beast Man with them where they regroup inside a cubicle.
Robin comes up with a plan to combat the Man, and does what "teens do best". He exits out of the cubicle and pulls out an iPod and turns up his music real loud with headphones on. The Man questions Robin what he is doing with no response as his music is too loud to hear his words. Cyborg and Starfire talk by communicating in "teen" phrases that makes nonsense while texting on phones, irritating the Man. He then finds Raven who is reading a teen magazine, where the Man says to stop reading that "garbage" and for her to do something with her life. Raven casually says "whatever", and shoots up her magazine in the Man's sensor, causing another error and causing the Man himself to malfunction and break.
With the destruction of the Man, Beast Man along with all the other adults are no longer being controlled, and instantly Beast Man transforms back into his younger self known as Beast Boy once again. Beast Boy happy he has his hair back, jumps into the arms of his best friend Cyborg who is happy to have him back, and comments that being an adult was terrible, and how he never wants to be one again.

In the original DC comics (as well as the one based on the first TV series) it is shown that Beast Boy's parents were scientists, and they died when Beast Boy was young in a boating accident after Beast Boy gained his powers. Though this may have been intentionally done for the purpose of comedy, and not to be treated as canon.
- His hair is slightly different in Housebroken Hero.
- In the original Teen Titans series, he was a pure vegetarian, eating tofu as a meat replacement, but in Teen Titans Go! he is more of a flexitarian. Evidence of this involves him wanting to eat the "Legendary Sandwich" which contains bacon, eating a hamburger in "Colors of Raven", and him competing in a Hot dog Eating contest in "Laundry Day" (many of the times, he eats them in his pig form) as well as eating pepperoni pizza in "Staring at the Future".
