- Ultraman Leo: Monster Ball (怪獣ボール Kaijū Bōru)
- Ultraman Z: Special Aircraft #1 (特空機１号 Toku kū-ki Ichi-gō)
One of the most powerful Capsule Monsters to be created from the Land of Light, 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 Go) 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. Even when Ashuran managed to throw Sevengar to the ground, the heroic machine responded by simply rolling over his adversary before getting to his feet and unleashing yet more powerful punches and slaps. However just as it seemed Sevengar was about to finish off Ashuran, he retreated back into his ball in a flash of bright light, having ran out of time.
Afterwards, Sevengar remained with Dan while Jack returned to repair the Ultra Eye.
- Further rubbing salt to the injury, the narrator points out that Sevengar would have won the fight if it fought for another 10 seconds.
- In the 2001 Ultraman Leo magazine, Sevengar's 1 minute limitation was hypothesized as a weakness invoked on its creators' part, since the Monster Ball could ended up falling into the wrong hands.
- Sevengar is the only Capsule Monster that appeared in Ultraman Leo's series.
- Sevengar was added into Ultraman Leo as children watching the show pointed out how while Dan could not transform into Ultraseven, he used his Capsule Monsters in his own series whenever such a problem arose. 
In episode 7, Sevengar along with many other monsters are seen cheering on Ultraman Ginga as he fights Dark Galberos.
It is likely that Sevengar returned to space in his original form after Ultraman Ginga defeated Dark Lugiel.
Sevengar is due to finally appear again, after almost four and a half decades after his first appearance. Here, it was the very first anti-monster robot built by human on Earth and is also used for disaster-relive missions such removing rubble. Despite its cute eyes expressions, they will change when it engaged into combat. The pilots are Haruki Natsukawa and Yoko Nakashima.
