Giga Battle Nizer

Giga Battle Nizer (ギガバトルナイザー) is a giant polearm variant of the Battle Nizer that is more powerful than a regular Battle Nizer as it can revive an army of hundred monsters. It is commonly regarded as Ultraman Belial's signature weapon. It was temporarily destroyed after the Ultras' battle against Beryudora and restored by Reibatos before Ultraman Belial receives it.

Past
After Belial's exile from the Land of Light and fusing with Alien Reiblood, Belial received this weapon and used it in the Belial Revolt, and used it to form the Belial Army. However, when Belial was defeated by Ultraman King, it was sealed in the Valley of Flames under the Monster Graveyard guarded by an EX Zetton.

Ultraman Mebius Gaiden: Ghost Reverse
As this item causes monsters to be revived including the Dark Four Heavenly Kings of Alien Empera's Empera Army, and its potential to revive the evil emperor, Ultraman Mebius was sent to retrieve it. When Mechazam appeared to help Mebius, he was revealed to have been a crucial element in the Emperor's resurrection. By uniting the Giga Battle Nizer with Mechazam, Empera would be revived. This did happen, but in a fight with Mebius and Ultraman Hikari, Mechazam sacrificed himself to keep Empera from ever returning with the Giga Battle Nizer being lost in space until it was retrieved by an Alien Zarab to form an alliance with Ultraman Belial.

Mega Monsters Battle Ultra Galaxy Legend Movie
Belial received the Giga Battle Nizer from Alien Zarab but Belial betrayed Alien Zarab and destroyed him with this weapon. Belial fought against the Ultras with this weapon and used it to revive his 100 monsters. After Belial's defeat as Beryudora by the Ultras, the Giga Battle Nizer was destroyed.

Ultra Fight Orb
When Reibatos arrived at the Monster Graveyard, he used his powers to restore the weapon in hopes of restarting Ultraman Belial's plan of reviving 100 monsters to rule the universe. Upon Reibatos' defeat by Ultraman Orb, the Giga Battle Nizer mysteriously dissappears and was somehow received by Ultraman Belial later on.

Ultraman Geed
Belial wields this weapon in the battle with the Ultra Warriors. It was used to summon theSuper-dimensional Eradication Bomb that allowed Belial to trigger the Crisis Impact. He arrives on Earth with this weapon and used it in battle with Zero and Geed. When Belial transforms into Belial Atrocious, he also wields it. During the final battle, Geed once again destroys it with his Geed Proof, blowing it to bits.

Weakness
A single Battle Nizer was able to control it and the monsters used. This is proven when Rei used his Battle Nizer to temporarily paralyse Beryudora giving the Ultras an opening to destroy the monster.
