OK K.O.! Let's Be Heroes/YMMV


 * Evil Is Sexy:
 * Raymond certainly qualifies, due to being part romantic robot (aside from being part sports robot as well). Some special examples range from him often speaking in a sultry tone, to three hens swooning over him in "Plaza Prom", to being titled a "Sporty Casanova" and Rad calling him handsome in "Let's Watch the Boxmore Show".
 * Cosma, after the events from "Deep Space Vacation". If her already wide hips weren't enough before, she can make herself bigger than a planet, has a smoother voice than before and makes a classy pose in front of K.O. and Enid.
 * Lord Boxman, with his green undercut and Big Beautiful Man status. His relationship with Venomous helps too.
 * Friendly Fandoms: Shares one with Steven Universe, mainly due to this show's creator having previously worked on the aforementioned show (and also being in a relationship with that show's creator).
 * Memetic Mutation:
 * On Tumblr, some people have started joking that OK K.O.! is trying to "outgay" Steven Universe (a show known for its blatant use of LGBT characters and relationships), citing the use of Joff and Nick, Enid and her strange interest in Carol, Red, and past relationships with Elodie and Rad, R.M.S. and Brandon, and Rad and Raymond.
 * After the episode "Big Reveal" aired, fans immediately decided that Carol would threaten Venomous into paying the 6-11 years of child support she never got.
 * Portmanteau Couple Name:
 * Lord Boxman/Professor Venomous = Voxman
 * Rad/Raymond = Radmond
 * Rad/Enid = Radnid
 * Red Action/Enid = Rednid
 * Elodie/Enid = Elonid
 * K.O./Dendy = Kendy
 * Mr. Gar/Carol = Garol
