Ernesto is a robot created by Lord Boxman to help manage Boxmore. He is an enemy in OK K.O.! Lakewood Plaza Turbo and OK K.O.! Let's Play Heroes.

Physical Appearance

Ernesto is a spherical purple robot with black and purple limbs, a black spherical head with a cycloptic eye, and a black tie paired with a matching top hat. Under the hat is a single spike, or a comb-over hairstyle as revealed in "Let's Watch the Boxmore Show". He also has very sharp, white fingers.


He so bureaucratic that he is unable to do anything without filling out the proper paperwork first. He has also never taken vacation days. Ernesto is usually seen chatting around the office cooler with another Ernesto. Though not used to fighting, Ernesto is surprisingly powerful in battle when given the proper motivation.

Most of the time, Ernesto is shown to be friendly and kind, especially to his younger siblings.

  • Divide: Ernestos can split their bodies at the waist and attack at two locations at once.

  • Tentacles: In "Rad's Alien Sickness", he could sprout tentacles throughout his body.
