Initially a basic Ultra Soldier, Ultraman arrived on Earth while pursuing an escapee of the Monster Graveyard; Bemular. In his pursuit, he accidentally collided with Shin Hayata, an officer of the Science Patrol, who was on a scouting mission in his jet. Hayata was killed in the same crash, but out of remorse, Ultraman gave Hayata his own life, and merged their bodies, to keep him alive. After Bemular was destroyed, Ultraman stayed to protect Earth from more threats, such as ancient monsters and alien invaders. Some memorable mentions are his encounters with the Baltan, his close match with Alien Mefilas, and his defeat at the deadly monster Gomora. However, his time on Earth came to a close after his battle with Zetton. His Color Timer was damaged in his fight with Zetton, in which his enemy used a weapon that Ultraman had not expected--one specifically targeting the Ultra Warrior's warning light. Zetton was left to be destroyed by the Science Patrol. Ultraman was retrieved by his superior, Zoffy, and was taken back to their home world.
