One of the most powerful capsule monsters to be created from Ultra Country, Sevengar was incased inside a football-like object and was on his way to Earth, being transported by Ultraman Jack to Dan as a present since Dan couldn't transform. Unfortunately, Jack was ambushed by the space monster Ashuran, and Sevengar was lost on Earth during the battle.
Once Jack and Ashuran landed on Earth, Ashuran went on a rampage, destroying anything in his sights while facing off against MAC. Meanwhile, Jack (as Hideki Goh) was trying to locate Sevengar's ball to stop the monster. Upon locating it, Jack returned to assist MAC and gave the ball to Dan, who desperately used the capsule, unleashing Sevengar to battle the monster itself. Surprisingly, Sevengar was able to handle Ashuran in battle with ease, easily beating down the monster despite all that was thrown at him. However just as it seemed Sevengar was about to finish off Ashuran, he retreated back into his ball and Ashuran retreated to recover due to running out time.
Afterwards, Sevengar remained with Dan while Jack returned to repair the Ultra Eye.
- Sevengar is the only capsule monster that appear in Ultraman Leo's Series.
- Sevengar is the second robots in the Ultraman Leo, the first was Gamerot. However, he is the only ally out of the two.
It is likely that Sevengar returned to space in his original form after Ultraman Ginga defeated Dark Lugiel.
