"Rad's Alien Sickness" is the 35th episode of Season 2 of OK K.O.! Let's Be Heroes and the 87th episode overall.

Official Synopsis

When our heroes are infected with a virus, Rad stubbornly refuses to back down.[1]






  • An indicator of Rad taking long to recover than Enid and K.O. was the color differences on their faces when they coughed after inhaling the fumes. Rad's face was blue while Enid's and K.O.'s faces were purple.

Production Notes

  • The episode's concept was thought of before "Boxman Crashes" and "All in the Villainy" until it was decided that the episode takes place after those episodes since it featured Professor Venomous and Fink as regular villains.[2]


  • Enid and K.O. claims that they never get to see Ernesto fight and usually comes once a season despite the fact he fought from previous episodes. However, they either probably meant a specific Ernesto, as Ernesto responded that "he is not just regular Ernesto" and Ernestos are only revealed to have numbers part of their names or they meant that the fact that he is battling alone instead of with other Boxmore bots as "OK Dendy! Let's Be K.O.!" had this and it was from Season 1.
    • Another claim that can be counteracted was when in "Sidekick Scouts", Ernesto says that he is trying to raise his credibility and to be impressive, which could support the fact the Bodegamen overlooked his presence in battle.
  • Ernesto was given an upgrade from Professor Venomous after he was not given from "Sidekick Scouts".
  • The way K.O. and Enid clasp their hands and heads together is similar to how K.O. did it with Rad in "Soda Genie".
