This is a list of the major and minor characters featured in and/or created specifically for the Cartoon Network animated series, Teen Titans Go!.
Teen Titans
Robin
Voiced by: Scott Menville (reprising) Robin is the leader and the only Titan who does not possess any superpowers. He primarily relies on his arsenal of weapons and tools during combat. His weapons of preference are his Birdarangs, grapple guns and multi-purpose metallic bo staff. He is also incredibly agile, and is a studious scientist, detective and martial artist.
Robin is disciplined and serious. Robin's role as leader is modestly parodied throughout the series. He prefers to take the lead role at all times. Robin is also at times emotionally unstable, arrogant and self-centered. However, despite his flaws he usually learns from his mistakes and tries to make amends.
His original comic book likeness is also featured briefly in "Books", and he is seen in his original comics outfit in a flashback in "Baby Hands". It transpires that Robin also eventually grows up to become Nightwing in "Staring at the Future", a point which is reinforced in "Sandwich Thief".
Starfire
Voiced by: Hynden Walch (reprising)
An orange-skinned, green-eyed alien princess, Starfire (real name Koriand'r) is formidable for her superhuman strength, faster-than-light flight, and ability to emit bright green energy bolts from either her hands or her eyes. Starfire is a generally happy and naive person and is relentlessly kind and polite to everyone, even to her occasional foes in battle. She expresses interests in self-maintenance to upkeep her appearance in the new series.
Starfire is slightly modified from her previous likeness, with design changes to her boots, hair, and flight trail.
Her original comic book likeness is also featured briefly in "Books", and she is seen in a less sexualized version of her original comics outfit in a flashback in "Baby Hands". It would also be revealed that Starfire would become the queen of her home world Tamaran in "Staring At The Future".
Raven
Voiced by: Tara Strong (reprising)
Raven is a mystical half-demon with a range of superpowers based upon her skills with magic. Her appearance slightly changed in the Go! series to have paler skin and shorter hair.
Raven is of a very apathetic and acerbic nature, almost seemingly devoid of emotion, and often interacts with her teammates through means of sarcasm and occasional bouts of demonic anger. Despite some parts of her personality staying similar, others were modified for the Go! series. She is shown to have feelings for her teammate Beast Boy but often hides it from everyone.
Robin categorized Raven's role in the group as "the sarcastic older sister" in "Uncle Jokes". She is seen in her original comics outfit in a flashback in "Baby Hands".
Beast Boy
Voiced by: Greg Cipes (reprising)
Beast Boy has a purple-and-black Doom Patrol uniform, pointed ears, and green skin. He is shown to have feelings for both Raven and Terra, he often goes to Terra if he tried to get Raven to go out with him on a date and will constantly be rejected everytime.
As in the comics, Beast Boy is very good friends with fellow Titan Cyborg, though their friendship would be tested at times.
His original comic book likeness is also featured briefly in "Books", and he is seen in his original comics outfit in a flashback in "Baby Hands". Beast Boy sings a modified version of Love Won't Fade, a song written and performed by Cipes' musical group to Terra in the Valentine's Day episode "Be Mine".
Cyborg
Voiced by: Khary Payton (reprising)
Cyborg is a tall, prideful cyborg. Much of his body contains an arsenal of hidden weapons, such as lasers and missiles, but includes various commodities and appliances. He has feelings for Jinx and once dated in "Opposites".
Unlike the original series, Cyborg is now a disembodied head connected by a small system of wires which make up a miniature body, making him more robot than human. However, this is often inconsistent from episode to episode.
His original comic book likeness is featured briefly in "Books,” and he is seen in his original comics outfit in a flashback in "Baby Hands." A chibi of Victor Stone, his human self prior to automation, is displayed briefly in "Caged Tiger.” Cyborg explains his origin story, accompanied by a thought bubble recollection of the event, in "Man Person.”
Allies
