K.O.

Main

K.O.

K.O. is the titular character and the main protagonist of the series. He is Carol's son and the newest employee at Gar's Bodega, which is located in Lakewood Plaza. His birthday is June 18, which is also the PIN for Carol's credit card. He is optimistic, loyal and willing to help others. Although he can be simple-minded and gullible, his friends find him reliable, and he deeply cares for them. He is also easily amazed by anything hero or weapon-related and is always looking for advice on how to be a proper hero, usually from Carol. In "Know Your Mom," K.O. believed that Carol quit being a hero when he was born, but later learns that this was not the case. The episode also shows that he did not know her name until then. K.O. has low intelligence, as for a long time he was unaware that Mr. Logic was a robot, or that Carol cooked his food, as he thought it came from the "Dinner Man". However. he occasionally showcases deductive reasoning and has been shown to be manipulative, particularly towards Darrell and Shannon. After being trapped by T.K.O in their subconscious in "Carl", K.O. accepts him as part of him in the series finale and becomes the new owner of Gar's Bodega in the epilogue.

His hero level gradually increased over the course of the series; initially starting at Level 0, he levelled up to 0.1, 1, 2, 3, 4 and then 99, attaining Level 100 in the time skip shown in the series finale. He was also Level 100 in "You're Level 100!", but this was due to a Pow Card glitch.

Enid Mettle

Voiced by: Mena Suvari (Pilot), Ashly Burch (series)

Hero Level: 5 (currently)

Enid Mettle is a teenage witch who works as a cashier at the bodega, claiming herself to be a ninja and that her werewolf father and vampire mother are a supermodel and spy, respectively. Enid is the most practical and down-to-earth of the employees, but seemingly lacks motivation in her job despite being shown to handle out-of-control situations; this is shown in the events of "We've Got Pests", where she convinced a group of partiers to grow up and discover themselves. When she was a preteen, she attended "Ghoul School", and was rather shy and insecure, being embarrassed of her family and wanting to be a ninja. After the events of "Parents Day", Enid learns to accept her family's quirks as her parents warm up to her career choice, later reconnecting with her old friends from Ghoul School. She and Red Action eventually start dating, and are shown running a dojo together in the series epilogue.

Radicles X

Voiced by: Ian Jones-Quartey

Hero Level: 4 (Currently)

Radicles X, more often known as Rad, is an alien teenager from Planet X, who also works as a shelf stocker at the bodega. Rad slacks off the most out of the trio despite claiming to be all-powerful and showing off. He boasts a tough masculine exterior, but is actually mild compared to other heroes and, as shown in "You Are Rad", possesses a softer side that he refuses to acknowledge out of fear of being embarrassed. In fact, Rad is more prone to crying than the others and is therefore much more sensitive to having his feelings hurt. In the series epilogue, Rad returns to Earth after having enlisting in the space army for some time and opens a cat cafe.

Mr. Gar

Voiced by: David Herman

Hero Level: 11

Eugene Garcia is the overseer of the plaza and owner of the bodega where K.O., Enid, and Rad work. He is tough, serious and prideful of the plaza and wishes for it not to be harmed. However, he has occasionally shown to not mind his employees slacking, as he considers it "normal". He finds it uncomfortable to be emotional around others, mainly Carol, whom he had feelings for but did not act on out of guilt. When he was younger, Mr. Gar was originally a P.O.I.N.T. member codenamed El-Bow who fell in love with his fellow recruit Carol, who was in love with their senior Laserblast. However, he was fired from P.O.I.N.T. after inadvertently distracting Carol from a stakeout which seemingly caused Laserblast's death. After some time, Mr. Gar was entrusted with the land he built the plaza on by the President of the Universe, who enlists him for several secret missions. In "T.K.O.," Mr. Gar opens up about how proud he is of K.O. while openly admitting his feelings for Carol. After a three-month time skip at the start of the second season, it is revealed that Mr. Gar and Carol have begun dating and that he has taken a father-like role to K.O.

Carol

Voiced by: Kate Flannery

Hero Level: 11

Carol is K.O.'s tough yet doting mother and the owner of "Fitness Emotions" at the plaza, which Ginger, Gladys and Gertie frequent. She usually gives K.O. advice, though it is not always clear what she is trying to teach. She is good friends with Mr. Gar, but is oblivious to his feelings for her. However, in "Seasons Change", she seems to acknowledge his feelings for her, but either seemingly does not care or knew about it all along. The episode also reveals that Carol had trained K.O. since he was an infant. When she was younger, Carol was originally a P.O.I.N.T. member code-named Silver Spark, who had feelings for the group's senior member Laserblast. His apparent death led her to initially bear a grudge against Mr. Gar for keeping her from preventing it, but later forgave him as he saved her life and knew of his crush for her. After a three-month time skip following the first season finale, she has started dating Mr. Gar and is revealed to still be a P.O.I.N.T. agent in secret, safeguarding the glorb tree under the plaza to prevent P.O.I.N.T. from intervening.

She ultimately values her time with K.O. and considers him a close friend. In "You're in Control", Dendy tells K.O. that she loves him and that he is appreciated, even admitting that he has helped her in the "emotional sciences".
