Beast Boy's parents, Mark and Marie Logan, were geneticists that would travel the jungles of the world to study their wildlife. Beast Boy was brought up in the jungles of Brazil, Africa, India, and several other places. The Logans particularly became interested in a rare species of green monkeys, but the day they finally found them, something terrible happened.
Beast Boy was bitten by a one of the monkey's and contracted a serious illness called Sakutia. To save him, his parents attempted to cure him with a new serum, which bestowed him with his shape-changing abilities. As a side effect, his skin, hair, and eyes turned green. Later in his life Beast Boy's parents died in a boating accident. After they died, Beast Boy, was interested in a super hero team called the Doom Patrol and was determined to join them. He broke into their headquarters and was treated as an intruder, but his efforts to escape capture impressed them, thus earning his membership on the team.
Beast Boy was originally the youngest member of the Doom Patrol. However, Mento's harsh discipline and less-than-encouraging attitude finally alienated him from his surrogate family, and he struck out on his own. Looking for a new place to live, he came to Jump City, where he encountered Robin, Starfire, Raven, and Cyborg and aided them in liberating Starfire from her Gordanian captors. Afterward, the five formed a new team on their own, the Teen Titans.
Throughout his career with the Titans, Beast Boy keeps exhibiting a very carefree jokester attitude which often causes a great deal of trouble, but he does have a strong sense for responsibility, which he rarely exhibits, though. Once he accidentally caused Cyborg to download a malevolent computer virus from a bootleg copy of his favorite computer game (Mega Monkeys 4) into the latter's
systems, causing him to rampage across the city, consuming everything in sight. Feeling guilty about what he had done, Beast Boy, together with Gizmo, who was press-ganged into assisting (since he and Cyborg share a mutual dislike), entered Cyborg's body in the form of an amoeba and finally managed to defeat the virus on his own.
Later on, during his first confrontation with Adonis, Beast Boy and his opponent were doused with experimental chemicals which triggered the emergence of a more feral side and the eventual transformation into a type of super-werewolf. In this form Beast Boy battled Adonis for Raven's life, and managed to defeat him. Afterward, he uses this werewolf form only one more time, when Slade, as a minion in the service of Trigon, attacked Titans Tower with an army of fire demons. He never used it after then, suggesting that even with the strength and abilities it gave him, he considered only using it as a last resort.
Season 5 of Teen Titans focuses on Beast Boy a great deal, as it deals with his history as a member of the animated series' incarnation of the Doom Patrol. In this season, Beast Boy exhibits a surprising amount of inherent leadership skills; he finally convinces Mento to think his way through a tough situation instead of muscling it, and when the Brotherhood of Evil attacks young superheroes all around the world, he leads Herald, Jericho, Pantha, and Más on an assault against the Brotherhood's headquarters. He remains leader even after Cyborg, Starfire, Raven, and several other Titans join the fight, only standing down after Robin is thawed.
Beast Boy trying to think about what to say to say to Terra
Beast Boy once fell in love with Terra and began a relationship. Beast Boy had a lot of support for Terra when she didn't feel welcome and she confided in him that she can't fully control her powers and made him swear not to tell. Slade tried to convince Terra to turn to evil and she wouldn't listen her powers went out of control. After defeating him, Robin by observation told her they know she couldn't control her powers. She felt betrayed by Beast Boy and ran off. Terra returned and wanted to be a Teen Titan. When Terra returned, Beast Boy was elated to see her again and she was equally eager to rekindle their relationship.[1]Beast Boy made heart a heart box for her and asked her on a date but at first said she couldn't. Beast Boy in his room was upset and how stupid he thought he was and terra listening on a rock in the window decided to go out with him. She asked if he trusted him and he said more than anyone. They went out on a date to an amusement park and Beast boy asked her if she's having fun and that he is. She said he's her definiton of fun. They had fun playing games, and going on rides, and taking pictures. On the ferris wheelW, Terra asked him if he knew something bad about her, would he still be her friend and he said always. They were about to kiss when Slade appeared. Beast Boy battled Slade. When Slade told Beast Boy, Terra turned to evil, he didn't believe it. When he found out she did, he was deeply hurt. While Beast Boy has carried a lot of resentment and rage towards Terra, he never failed to forgive her and offer her support when it mattered. All the other Titans regarded her as evil when he still saw good in Terra. Beast boy brought up that they never gave up on Robin when he was Slade's apprentice. So Robin battled Terra for a second chance but she refused. Slade was totally controlling Terra and Beast Boy gave her confidence to fight against him and she kicked Slade into the lava. Beast Boy and Terra shared one last embrace before she stopped the volcano and was petrified. Terra fought Slade and pushed him into the lava. Terra hugged Beast Boy and told him he's the best friend she ever had.
