The Red Sentient 5 is Krytus' personal team, which is basically the Red Sentient equivalent of the Battle Force 5. It is possible that Sage had created the BF5 based on the RS5. Unlike the rest of the Red Sentient population, they were off-planet during the time Sage had used the Double-Helix Crystals to freeze the Red Sentients. Krytus's team was imprisoned by Zemerik, but later freed by Krytus once he escaped the Krypt Zone. Each member can form his/her own vehicle with special properties similar to BF5's. Their main shared weakness is through breaking their shells and releasing their life essences.

  • Krytus (voiced by Brian Drummond) - Leader of the Red Sentient 5 and Sage's twin brother. Krytus possesses high amounts of strength, the ability to form blades from his hands, and can control the Sark and turn them Red. He created Zemerik to lead his army, until Zemerik turned on Krytus and imprisoned him in the Krypt Zone. Because they are twins, Krytus and Sage share a weak telepathic link, which Sage uses to locate him. Though physically stronger, his mental powers are weaker than Sage's. As the leader, he is Vert's counterpart. He also made "re-spawn" chambers for him and his team so that if any of them are destroyed in battle, they will revive in them. Krytus is probably the true villain behind the events of the entire series.
  • Kyrosys (voiced by Mark Hildreth) - RS5's Artillery Expert. Kyrosys is an arrogant Red Sentient. He is also Stanford's counterpart.
  • Krylox (voiced by Colin Murdock) - RS5's Strategic Tactical and Tech Support. Krylox is a large, hulking Red Sentient with incredible strength and the ability to duplicate himself. He is not very bright and prefers to solve all his problems by smashing things with his fists. His weakness is that if one duplicate is damaged, the other will be damaged in the same place as well. He is Sherman and Spinner's counterpart.
  • Kytren (voiced by Michael Dobson) - RS5's Scout. Kytren is Zoom's counterpart. His blue sentient twin is Sol who appears in one episode. Unlike the other Red Sentients, he has a tendency to speak in brief sentence fragments, due to his savage nature.
  • Kyburi (voiced by Kathleen Barr) - RS5's Special Operations Officer. Kyburi is a female Red Sentient and Agura's counterpart. Short-tempered and cruel, she is Krytus's First Lieutenant and Hunter. She has the special ability to drain energy from machines and living beings.
