Radicles is nearly the same height as Enid. He has a muscular build, turquoise skin, pointed ears, and antennae.
He wears light pink pants, black heeled boots, and a blue crop top with the bottom edges torn, showing his stomach.
Radicles is shown to be a slacker, as he is seen sleeping on the job and moments later, deciding to take a break in the pilot. He also appears to be boastful, as shown in "Let's Be Heroes", he brags to KO about his strength as soon as he meets him.
He often shows off his special move like it takes no effort. He is shown to look up to Mr. Gar, as he texted KO in the pilot about Mr. Gar being "really cool.".
Rad's special move is the Power Poke. The Power Poke forms the shape of a pointing hand and has the ability to push people with considerable force, enough to blast KO into the sky. Rad also has the power to levitate at will. When he does this, he is surrounded by a purple glow and he sits in a cross-legged position.
- Rad's power poke resembles the Finger Beam technique from the Dragon Ball series.
- Rad's original name was "Radimus"
