Ultraman Titas is one of the three main Ultra Warriors in Ultraman Taiga. He debuts along with Ultraman Taiga and Ultraman Fuma as the first Ultra Warriors in the Reiwa era. He is a warrior and a sage from Planet U40, the birthplace of Ultraman Joneus. With his carefully trained body and healthy spirit, he is skilled in heavyweight battles.
The light of Titas traveled to Earth along with the soul of the wife of the dead astronaut Rento Kujo, who was inside a Galactron MK2. Titas' light managed to reunite the couple, who finally passed away in peace after Rento gave up on his revenge. Titas met Hiroyuki Kudo and swapped with Taiga, who was injured from the battle with Galactron and made short work of the robot before going to space to destroy the falling satellites, but Tregear attacked him. Titas refused to fight back until he destroyed the falling satellites first.
Taiga, Titas and Fuma are reunited during the battle against Darebolic, and the Tri-Squad continues to protect the Earth along with Hiroyuki and EGIS.
