Zamsher group

Zamsher group (ザムシャー族) are a race of gigantic aliens themed after Sengoku Era warriors. One single member debuted in Ultraman Mebius, while variations of this race appeared in Mega Monster Rush Ultra Frontier.

Ultraman Mebius
The first member of this race debuted in this series as a space who wanders around the universe in hopes of fighting against formidable opponent. After facing against various aliens, Zamsher went to Earth in hopes of challenging Hunter Knight Tsurugi but a series of events on said planet and his encounter with Ultraman Mebius changed his initial impression of the rookie Ultra Warrior, departing to space in hopes of becoming stronger.

Sometime later, Zamsher's Hoshikirimaru was fixed by Ultraman King as he met two other aliens that befriended the GUYS members during their time on Earth. After facing against Alien Ateria, they return to Earth to assist GUYS members in facing against Alien Empera. Zamsher loses his life when fighting alongside Ultraman Hikari, leaving his Hoshikirimaru for the blue Ultra to use.

Mega Monster Rush Ultra Frontier
In addition to the original Zamsher, three other members of this group appeared with different armor and weapons.

One of the members, Nodachi Zamsher appeared in Guts Gunner Garm's flashback in one of their fight against Antlar.

Trivia

 * Nodachi Zamsher's voice: Kenta Miyake
 * The Zamsher group members that debuted in this game had their names themed after their respective weapons.
 * The name of Nagina Zamsher's weapon is an inversion of Zamsher's Hoshikirimaru: whereas the latter "slices" star, the former "fused" them.
