Red Sentients are an interdimensional alien race from Hot Wheels: Battle Force 5. They are made of anti-matter energy and a high-density crystal. They are expert fighters and create advance vehicles. They were at war with their sister-race, the Blue Sentients. The war came to an end when both sides settled their difference and established a truce. But one Red Sentient named Krytus plans to rally his race to attack the Blues again and take over the Multiverse. Then Krytus's twin sister, a Blue Sentient named Sage learned about his plan and decided to strike first. She used the Double-Helix Crystals to freeze the entire Red Sentient race. Krytus and his team were off-planet at the time, so they weren't frozen. Sage was able to steal Krytus and his team away for hundreds of years.
A while after Krytus's release, he planned to unfreeze his entire race. But thanks Sage and the Battle Force 5, they were able to resurrect the entire Blue Sentient race. While Krytus returned to the Red Sentient planet to rally his people, he realized Sage and the Blue Sentients got there first. The Red Sentients were tired of fighting, and would not be persuade by Krytus authority. For his crimes, he was banished, and the Red and Blue Sentients were at peace once again.
