Tyrant is a monster born in Neptune that combined the outstanding parts of several Kaiju defeated by the Ultra Brothers in the past.
After defeating Zoffy who was patrolling in Neptune, Tyrant faced against the other Ultra Brothers on the other planets, defeating all of them.

Tyrant’s high endurance makes it able to withstand Ultraman Jack’s Spacium Ray and Ace’s Metalium Ray.
Tyrant can also travel from Saturn to Earth in just 20 minutes.
After Tyrant arrives on Earth, it starts a fierce fight against Taro, and Tyrant’s grappling hook was cut off by Taro’s Blue Laser during the fight. The hook was then transformed into Ultra Lance with the King Bracelet, which was thrown back, destroying him.
