"Although we're born on different planets..."
"We all head to the same place!"
"We are...the Tri-Squad!"
- ―The Tri-Squad's reunion call
The Tri-Squad (トライスクワッド Torai Sukuwaddo) is a trio of Ultramen with different origins who join forces to preserve peace in space. It was founded by Ultraman Taiga, along with Ultraman Titas and Ultraman Fuma.
During Taiga's stay on Planet U40 under the care of Ultraman Joneus, he met Titas who decided to join him in his adventures. When they arrived at Planet O-50 to defend the Warrior’s Peak from aliens who wanted to destroy it, they met Fuma. Thus, the Tri-Squad was formed. At some time, they went to Planet Dino to fight against a robot army, and were almost sucked into a black hole.
Twelve years ago, the newly formed Tri-Squad attempted to fight Ultraman Tregear after the other New Generation Heroes had been defeated. As a gift, the New Generation Heroes gave their light to the Tri-Squad. Taiga, Titas and Fuma ignored Taro's warning not to fight Tregear and attacked him. Despite being able to strike him a few times, their combined strength was not even close to enough to defeat him. Titas and Fuma were reduced to particles, which enrages Taiga. He charges ahead, but he also shared the same fate as his comrades.
One by one, the Tri-Squad descended to Earth and bonded with the human Hiroyuki Kudo. Taiga was the first to arrive on Earth, having floated around for years until he decided to save Hiroyuki's life after witnessing his bravery.
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 then joined Taiga and Hiroyuki.
Fuma's light was bound to a crystal in a pendant, that had been traded around many times and somehow ended up in the possession of the Villain Guild, more specifically Volk. When the Deavorick (MB) was released, the building it was stored in collapsed in an explosion, injuring Volk, who decided to show the pendant over Homare Souya. Fuma's voice unexpectedly speaks to Taiga, and his light flies over to Hiroyuki, finally reuniting the Tri-Squad.
