Subtitle: Giant Space Monster (宇宙大怪獣 Uchū Dai Kaijū ).
The Return Of Ultraman Edit
His height is around 46 Meters tall. He weighs around 61,000 Tons.
Bemstar was an energy absorbing monster from the Crab Head Nebula. It came into the solar system looking for cosmic energy, eating a highly developed space station monitored by MAT. Bemstar soon landed on Earth, attacking a nearby city where MAT counterattacked. Ultraman Jack arrived to do battle, but the beam absorbing alien withstood against most of Jack's attacks, even absorbing the Specium Ray into his gorge.
Jack became extremely weak using up most of his attacks on Bemstar and as a result, tried to go towards the sun for more energy to recover, but the amount of energy the Sun had caused Jack to faint and thus passed out, hurlting towards the sun's atmosphere. Just then Ultraseven arrived just in time to save Jack! After a brief discussion, Seven gave Jack the Ultra Bracelet, a shapeshifting weapon that stuck to Jack's wrist. Jack, now rejuvenated returned to Earth and fought Bemstar again, this time with greater enthusiasm. Then, Jack took the Ultra Bracelet and severed Bemstar's arms and head, ending the monster's thirst for energy.
Some time later, both Bemstar and the monster Seagorath were revived by Alien Nackle when he came to Earth. However, Jack manages to beat them both with ease (which is seen as mere stock footage of their previous battles.)
This Monster reappeared in Redman.
Ultraman Taro Edit
This Monster reappeared in Ultraman Taro as Advanced Bemstar. His height is around 80 Meters tall.
In this series, Bemstar was created by Yapool with enhanced powers and thus gain the aliases, "Advanced Bemstar." He was then sent to attack Earth, eating some satellites in space and then attacking in an oil refinery. At first, ZAT tried to cut him to pieces like Ultraman Jack did to the original Bemstar, by using a giant buzzsaw. However, Yapool gave his creation "slice resistance," therefore the plan failed. Ultraman Taro appeared to do battle, but like in Jack's first battle, Taro found himself beaten down by Advanced Bemstar and had to retreat.
A few days later, Advanced Bemstar reappeared again in the same oil refinery as before. ZAT and Ultraman Taro returned to do battle as well, but this time Taro and ZAT had a much better fight against the monster. Fearing the worst, Yapool summoned weaker versions of his choju, Sabotendar and Verokron to help Advanced Bemstar, but they were no match for Taro's might and ZAT's assaults. In the end, Verokron fell to ZAT's might, Sabotendar was destroyed by Ultraman Taro, and Advanced Bemstar was destroyed when two missiles collided inside his gorge.
Ultraman Mebius Edit
This monster reappeared in the series Ultraman Mebius.
Much like his predecessors, Bemstar was first discovered attacking a space station. However, Ultraman Mebius started to get worried about Bemstar's arrival as he had heard several stories about Bemstar's might upon the Ultras before him. He started to doubt that he could beat it, but he knew he would have to face his fears eventually as Bemstar was getting closer to Earth. Upon landing, Bemstar proved his might, shrugging off most of GUYS weapons and snatching Marina (of GUYS) inside her aircraft. Ultraman Mebius appeared, and saved her just in time. Both Mebius and Bemstar seemed evenly matched, until Bemstar tried to eat Mebius with his gorge. Mebius got loose, and GUYS tried to freeze Bemstar's stomach, but Bemstar managed to blow it off, and recover. Mebius then decided to transform into his new Brave Mode. He then created his new Mebium Sword, and sliced Bemstar in half, destroying him completely.
Sometime later, GUYS was chosen to test out new arrivals of Capsule Monsters. One suggestion was Bemstar, it had the strongest chance of becoming useful to the team but was ultimately turned down due to Marina's refusal to work with the monster that nearly ate her.
Ultraman Mebius Side Story: Hikari Saga Edit
After leaving the Earth, Ultraman Hikari was attacked by a stray Bemstar. Hikari chased the monster around the astroid belt, eventually taking their battle to small, deserted planet. Bemstar was easily winning, beating down and injuring Hikari as he could only watch as Bemstar moved in for the kill. Just then Zoffy arrived and after some motivational words were given to Hikari, The two joined forces and eventually managed to destroy Bemstar.
Another Bemstar was seen flying overhead towards Earth. This would be the one that fights Ultraman Mebius (Zoffy told Hikari to "let Mebius handle that one.")
Ultra Galaxy Mega Monster Battle Edit
This Monster reappeared in the series Ultra Galaxy Mega Monster Battle.
Bemstar descended into the area and quickly attacked the ZAP SPACY. One of the team members, Haruna took one of their aircraft attacking it head on (It appears that this Bemstar had murdered her brother prior to events in the show,) but Bemstar took little notice and resumed to approach the ZAP SPACY. Rei released Gomora to battle Bemstar, but the fight was evenly matched even with the assistance of the vengeful Haruna. Rei then summoned Litra to attack on Bemstar but ultimately proved futile as Bemstar absorbed Litra's fireballs and powered up, beating down Gomora. Then noticing a weakness, Litra fired the fireballs causing Bemstar to absorb them again, which had lead him wide open for an attack. After Gomora punctured Bemstar's chest and fired his Super Oscillatory Wave, Bemstar was finally destroyed.
Ultra Galaxy Mega Monster Battle NEVER ENDING ODYSSEY Edit
This Monster returned in the sequel series Ultra Galaxy Mega Monster Battle: Never Ending Odyssey.
While the separated ZAP SPACY crew mates were stuck in space, a stray Bemstar appeared and started attacking. Luckily, the Pendragon's arsenal managed to scare off Bemstar to a nearby asteroid. Dail, a rogue member of the Reionyx Hunters finished the job himself, using the Pendragon's most powerful weapon, killing Bemstar in cold blood.
Mega Monster Battle: Ultra Galaxy Legend The Movie Edit
This Monster reappeared in the movie Mega Monster Battle: Ultra Galaxy Legend The Movie.
In this film, Bemstar was partnered up with the monsters Dorako and Saramandora as their leader, Alien Shaplay ambushed the Ultra Brothers. However, they were met by surprise from Dan's capsule monsters Windam, Miclas, and Agira. Bemstar fought Miclas.
After Rei and Mirai (Ultraman Mebius's host) were rescued, Miclas hurled Bemstar into a wall of ice and finished him off by kicking him through it, literally beating Bemstar to death.
During the climax when Beryudora is formed, Bemstar helped Ultraman Belial form Beryudora's face.ja:ベムスター
