"We'll save it [the world] or die trying. It's why we were given a second chance."
- ―Chuck Gavin, Ultraman: The Adventure Begins
Ultraman Chuck (ウルトラマンチャック Urutoraman Chakku), also known as Ultraman Chack, is the oldest and leading member of the Ultra Force, this Ultra Warrior, combined with stunt pilot Chuck Gavin after his arrival, caused a trio of pilots to crash.

Ultraman: The Adventure Begins
Ultraman Chuck arrived with the other members of the Ultra Force at the time of the Flying Angels accident and merged with the Chuck Gavin, leader of the Flying Angels.
After the accident the Ultraman Chuck lay dormant within the body of the Gavin until the Ultra Force dealt with the Sorkin monster Zoon. After realizing that Zoon was harmless Gavin's plane was accidentally damaged by Zoon's wings. After failing to control the out of control plane, Gavin transformed into Ultraman Chuck for the first time. He then rescued Zoon from the National Guard sent the monster on a course to a suitable planet where Zoon could live out the rest of his days in peace. However, this act was looked on as treason by the guard and the heroes were attacked by long range missiles.
With the Ultra Force believed to be dead, it seemed as if nobody would arrive to help the battle against King Myron in New York. However, the three heroes did arrive. After the creature brought down the aircraft, the three Ultras confronted it. Despite their power, they were overpowered by the beast and defeated. With their energy draining fast, King Myra continued to rip New York City apart. The Ultra Force mother ship, however, would soon recharge the guardians with power. With newfound strength and a new plan, the three managed to drive the creature back. It tried to retreat, but was stopped by Ultrawoman Beth's Ultra Spout and then captured by Chuck’s energy bubble. It lashed out with its tentacles, but the three only used them as ropes to drag the raging creature along for the ride. Within minutes they arrived at their destination: the sun. The trio dumped the beast in the fiery source of life, eliminating it. More creatures, however, could pop up at any given time, and the three heroes were granted their wish to remain on Earth.
