K.O. (OK K.O.! Let's Be Heroes)

K.O. (sometimes just written as KO) is the main protagonist in the ''OK K.O.! Let's Be Heroes'' series. He fights those of Boxmore, along with Radicles and Enid. His employer is Mr. Gar, the owner of Lakewood Plaza Turbo.

Physical Appearance
K.O. is a small boy who has tan skin and black eyes. He has dark brown jagged hair that is somewhat in the shape of a square at the top and is held together with a red sash band. K.O. wears a low-cut white tank-top with a blue sleeveless jacket, which is his Gar's Bodega's standard uniform, and dark blue shorts. He also wears red wristbands, pink leg warmers and is barefoot.

Personality
K.O. is an eager young kid boy who wishes to be one of the world's greatest heroes and to make his mom proud. He is willing to learn anything that would make him a great hero, such as friendship. Extremely loyal to Lakewood Plaza Turbo, he is optimistic about anything that comes his way.

K.O. has a strong willpower and courage but is very naive. He often shows that he wants nothing more in the world than to help people, as it would help him to get closer to his goal of becoming a true hero and because it feels good. According to Dendy and her data, she believes that K.O's desire to help others comes from a lack of a father figure and wants to gain love from others in order to fill that void despite having a loving and caring mother.

It has been shown that K.O. is sensitive when it comes to the subject of his father since he never knew him well. K.O. has been shown to be a "mama's boy" as he loves and adores his mother, Carol, and sees her as the greatest mom in the world. He still refers to her as his "mommy" from time to time. Despite how good-natured K.O. is, he can still become greedy and arrogant under circumstances where he feels he is in power.

In "Face Your Fears", K.O. faced a shadowy villainous form of himself who was incredibly strong. It is unknown what this form of him truly represents, but it can be implied that K.O. possibly fears being drawn to the "dark side" and hurting others. This form appeared in the episode "T.K.O."

Abilities and Powers
K.O's overall strength and agility, despite only having a 0.1 power level, are impressive for a kid of his age. However, by comparison, he is still weak compared to Rad and Enid, who both have been working for longer than him. K.O, while strong, still has trouble punching through solid metal without the assistance of Dendy.

Physical Strength
He assumes to be very strong, as in the pilot episode where he could easily lift and throw out of the store a malfunctioning freezer. In one case, he carried everyone in the plaza with one arm. K.O. is also very fast, as he's able to move around the Plaza and clean it completely with ease.

He is a quite accomplished hand-to-hand fighter, thanks to his training under the tutelage of his mom and his days working and practicing with Enid and Rad. He could face Darrell and Shannon in many occasions (although sometimes with the aid of his friends). In "T.K.O.", he faced and managed to defeat him and lock him back to his cage. In "Let's Have a Stakeout" he could resist and counterattack in his battle against Shadowy Figure, despite the later's superior fighting skills.

Special Move
KO's Special Move, entitled the Power-Fist Fireball, is similar to that of " " from and "" from. Consists of a powerful energy punch surrounded by blue flames which is delivered from one of his fists. This special move is strong enough to destroy many Jethro's robots, tossing Shannon to a tree in "Rad Likes Robots" and break a steel door in "Let's Have a Stakeout".

K.O. appears to have complete control of this special move. However, In "T.K.O.", he looks to have problems to summon it.

Miscellaneous Skills
One of K.O.'s most influential and notorious characteristics is his charm and optimism that he uses to motivate and cheer up his friends and allies. He can get along well with almost every person he meet.

In the episode "Face Your Fears" it's revealed that K.O.'s fear resist level is 15, overpassing Rad's 10 and Mr. Gar's 8 level respectively, which proves that K.O. has a very brave attitude. In the same episode, he even successfully helped Enid, Rad and Mr. Gar to overcome their greatest fears while they were trapped in the super extra hard level of the video game Face of Fear.

Turbo K.O. is the embodiment of anger and rage K.O. holds within himself. It is unknown where the form came from. His T.K.O. form not only increases his power, but gives him additional powers like super speed, strength, and levitation. Although his power increases, T.K.O. is more violent, bitter and ruthless than K.O., thus making him more dangerous.
