Sevenger (セブンガー Sebungā), is a robotic Capsule Kaiju who first appeared in Ultraman Leo, episode 34 as the fourth official member of Ultraseven's set of Capsule Monsters. After a long absence, a second Sevenger appears in Ultraman Z, this time as a human-built machine and part of STORAGE's arsenal.
- Ultraman Leo: Monster Ball (怪獣ボール Kaijū Bōru)
- Ultraman Z: Special Airborne Armor 1 (SAA-1) (特空機１号 Tokkū-ki Ichi-gō lit. Special Aircraft #1)
One of the most powerful Capsule Monsters to be created from the Land of Light, Sevenger was encased inside a capsule-like object and was on his way to Earth, being transported by Ultraman Jack to Dan Moroboshi as Dan couldn't transform due to his Ultra Eye being broken. Unfortunately, Jack was ambushed by the space monster Ashuran, and Sevenger 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 Sevenger'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 Sevenger to battle the monster itself. Surprisingly, Sevenger was able to handle Ashuran in battle with ease, easily beating down the monster despite all that was thrown at it. Even when Ashuran managed to throw Sevenger to the ground, the heroic machine responded by simply rolling over its adversary before getting to its feet and unleashing yet more powerful punches and slaps. However just as it seemed Sevenger was about to finish off Ashuran, it retreated back into his ball in a flash of bright light, having ran out of time.
Afterwards, Sevenger remained with Dan while Jack returned to repair the Ultra Eye.
- Shortly after Sevenger retreats, the narrator points out that Sevenger would have won the fight if it fought for another 10 seconds.
- In the 2001 Ultraman Leo magazine, Sevenger'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.
- Sevenger was added into Ultraman Leo as children watching the show pointed out how while Dan could not transform into Ultraseven, he used his Capsule Kaiju in his own series whenever such a problem arose. 
Sevenger along with many other monsters are seen cheering on Ultraman Ginga as he fights Dark Galberos.
It is likely that Sevenger returned to space in its original form after Ultraman Ginga defeated Dark Lugiel.
Sevenger was the very first anti-monster robot built for use by STORAGE, and is also used for disaster-relief missions such as removing rubble. When fighting, Sevenger's eye expression changes to become serious. Its pilots are Haruki Natsukawa and Yoko Nakashima on a rotation shift.
- Sevenger is featured as STORAGE's emblem, indicating that the machine serves as a 'flagship' robot for the organization.
- Within a week since the premier of Ultraman Z, soft vinyl figurines of Sevenger were sold out quickly in Japanese stores.
