Coding is not a power I was born with. I learned coding from scratch, it is how I express myself. It took a lot of effort, but it was fun, even though it wasn't always easy. With enough dedication, anyone can have this power, even you K.O.
|—Dendy, Dendy's Power|
Dendy is a major character in the OK K.O.! series. She is a young hero and works primarily with gadgets and technology. Her first introduction in the series was in the short, "Dendy", and her first episode appearance is in the episode "I Am Dendy".
Dendy is short in height and is almost as tall as K.O. She has light green skin (though it is only green in official artwork, as in the series proper, her skin looks Lemon-Chiffon) and short chin-length, olive brown bob-cut hair. She wears cerulean goggles with light cyan lenses, a golden yellow jumpsuit, and short sky blue boots. She usually carries a teal-colored technological backpack (In the game OK K.O.! Lakewood Plaza Turbo, her backpack is colored orange). Her skin is shown to get progressively greener as she ages, as seen in "Thank You for Watching the Show".
As of Season 3, Dendy now wears a beret the same color as her backpack. It is revealed in "You're a Good Friend, KO" that she wears it to cover up the pond she was starting to form in her head, something she says that all Kappas start to form as they grow. She is self conscious about it, but as she grows more comfortable with it, she keeps the beret because it looks cool.  Her head pond contains a goldfish and a single lilypad.
Early concept art for the show depicted Dendy as an elf or goblin-like creature with pointed ears. According to series creator Ian Jones-Quartey, Dendy had always been intended to be "non-human", though it wouldn't be until later into the series' development before they settled on making her a kappa.
Dendy is very intelligent and driven and enjoys helping friends. The first friend Dendy made was K.O.; the two met when Dendy requested his help finding backpack supplies in "I Am Dendy" as an excuse to hang out with him. Dendy can seem a bit distant and does not seem to understand social norms, but is enthusiastic and kind once befriended. When pursuing a goal, she sometimes shows a lack of regard for others, as demonstrated in "I Am Dendy" when Dendy suggests dismantling Mr. Logic in order to get a glorb, or in the episode "Mystery Science Fair 201X", when she experiments on K.O. without a regard for his well being, simply to push him to his limit. Despite this, Dendy means well and is a truly wonderful kid, and wishes to develop beyond her current view of just science, and learn about how to be open with her emotions. Dendy also has a large collection of Pow Cards.
Abilities and Powers
As seen in the short, "Dendy", she has the ability to change objects into other objects, (ex. changing a tree into an elephant) with the use of her computer backpack, which she refers to as a 'hackpack'. The backpack can also be used to alter the behaviors of objects, as shown when Dendy uses it to make the junk-fish free K.O. in "I Am Dendy." Dendy may have invented the backpack, in which case she'd be a gifted inventor, but this is unclear. Dendy is also very intelligent and knows how to use and manipulate various technologies, as shown in "I Am Dendy" when Dendy is able to quickly dismantle and reassemble Mr. Logic's hair trimmer, and in "Face Your Fears" when Dendy knows how to use the helmets to connect multiple people to the fear game. Dendy also knows how to break into a van, and therefore might how to break into other things as well. Dendy seems to have background knowledge on a variety of subjects, as demonstrated in "We've Got Fleas" when Dendy knew that in order to become an animal, one would have to be bitten by a were-animal.
Dendy has also been shown to be extremely fast and strong, able to run at speeds shown to rival or exceed K.O.'s, and she can easily pull K.O. alongside her while running. She can also jump really high thanks to her suit providing electricity to her feet as seen in "Dendy's Power".
