Aqualad (voiced by
Wil Wheaton) makes his debut in the episode "Deep Six", employing the help of the Teen Titans in defeating an Atlantean criminal named Trident. He butts heads with Beast Boy in that episode as he feels shown up by the impressive young Atlantean, but in their battles with Trident, Beast Boy and Aqualad make peace by the episode's end. He returns in "Wavelength", needing the Titans' help to take out Brother Blood's second undersea
H.I.V.E. headquarters. Following Blood's escape, they give chase and track him to Steel City, where he and Bumblebee form the
Titans East. He later falls prey to Blood's mind control, turning on appointed leader Cyborg and does battle with Titans Central; he is freed after Cyborg defeats Brother Blood in the final battle, and stays on with Titans East.
Argent Argent (voiced by
Hynden Walch) is a female Honorary Titan who first appears in "Calling All Titans". Deputized by Starfire while walling off a fractured dam, she is soon attacked and captured by General Immortus and flash-frozen at the

Bumblebee Bumblebee (voiced by
T'Keyah Crystal Keymáh) is introduced as a H.I.V.E. student, but is later revealed to have been a spy in the organization working in league with Aqualad. As she reveals in a staged fight with Cyborg, she is immune to Brother Blood's hypnotic influence. She later becomes a founding member of Titans East, convincing Cyborg to become the team's leader, when in fact it turns out to be an elaborate trap staged by Blood when she falls back under his control, though she appeared to be the only one of the group able to occasionally slip free. After Blood is defeated, Cyborg steps down from Titans East, making Bumblebee the new leader.
Bushido Bushido is a young silent Japanese swordsman, who is made an Honorary Titan to fend off an incursion by the Brotherhood of Evil, which is preparing to mount an assault on young heroes. He is given his name due to the fact that it is the only thing he can say or understand. A primal predecessor of contemporary human beings, he has an enhanced level of agility and strength. When Kole activates her crystallization powers, Gnarrk is able to use her body to great effect as a bludgeoning tool.
Herald Herald (voiced by
Khary Payton) is a young hooded African American boy who is made an Honorary Titan in the wake of the Brotherhood's efforts to seek and destroy the next generation of superheroes on Earth.

The five succeed in infiltrating the Brotherhood's fortress in Paris and ultimately freeing the captured heroes; Herald himself is called upon to save everyone when the Brain, forced into retreat, triggers a massive bomb designed to take out the entire complex. He is a
pyrokinetic young hero who is made an honorary Titan in the wake of the Master of Games' defeat. In his normal state, he has the appearance of an adolescent African American male, but when employing his heat-based superpowers, he becomes a fiery humanoid.
Jericho Jericho is another honorary titan who, alongside Herald, is summoned to the Titans' rendezvous point after the Brotherhood conducts their search-and-capture campaign on the team members across the globe. Jericho is a gentle and kindly albeit mute boy with the ability to possess others via eye contact, taking full control of their bodies, memories, and abilities, the only evidence of which is the black and green eyes the victims assume once possessed.

They arrive from the clouds, wreaking havoc on the city in which the Teen Titans live; Beast Boy later deduces that the duo is not evil, but rather misunderstood—they display their destructive powers in acts that they perceive as innocent fun, and battle the Titans on occasion, seeing the challenge as mere roughhousing. The two are later manipulated into creating a fire creature by Slade, who is in the guise of an Asian shaman; however, the two learn the error of their ways thanks to Beast Boy and go on to become heroes allied with the Titans.
