Rainboa is the Omnitrix's DNA sample of a Pytholeptic from the planet Serpnosis in 5 Years Later.


Rainboa is a long snake-like alien, covered with scales of various colors. He wears black uniform with white and green stripes on the lower, middle and upper part of his body. The Omnitrix symbol is located on his head.


  • Color-Based Hypnosis- Rainboa can stun or hypnotise enemies by rapidly changing colors of his scales. He can also use this ability to control his prey with simple commands.
  • Enhanced Strength- Rainboa posesses great strength.
  • Enhanced Speed- Rainboa is able to crawl very quickly.
  • Night Vision- Rainboa has an ability to see in the dark.
  • Sharp Fangs- Rainboa has razor-sharp fangs.


  • Lack of Arms- Since Rainboa does not have arms he has to rely on quick strikes with his fangs.
  • Blind Opponents- Enemies who don’t rely on their sight or are blind are unaffected by Rainboa’s hypnotic abilities.


His homeworld of Serpnosis is a swampy planet with large forests that cover its surface in near total darkness. This enhances the power of his color-changing scales in order to stun prey with hypnosis. They are very solitary creatures and don’t get along with their own kind outside of mating season.






  • Rainboa has an unhingeable jaw, just like regular snakes.
  • Rainboa shares the same homeworld as Monkiwi.
