The Battle Nizer (バトルナイザー Batoru Naizā) is a device used by Alien Rayblood's Reionics, such as Rei and Kate, that allows its wielder to summon a monster through a system called MonsLoad (モンスロード Monsurōdo). A Reionics commands the monster, even when the monster gets injured too much, so that the Reionics has no choice but to call him back. However, the Battle Nizer has a side effect of hurting the Reionyx as well.
The regular Battle Nizer used by Reionics, they can store up to three monsters at a time.
Neo Battle Nizer (ネオバトルナイザー Neo Batoru Naizā) is an evolved Battle Nizer used by Grande and Rei. It functions very much the same as the regular Battle Nizer but it can only be controlled by a powerful Reionics and in turn cause their monsters to grow in strength.
Giga Battle Nizer
- Main article: Giga Battle Nizer
Originally Ultraman Belial's personal Battle Nizer, given to him by Alien Rayblood. Belial used it to control 100 monsters and attack the Land of Light, an event that became known as the Belial Revolt.
- All users of the Battle Nizers have been Reionyx, how they obtained them is unknown but they may simply appear due to their Reiblood genes.This is may explain where Belial's Giga Battle Nizer came from.
- In episode one of Ultra Galaxy Neo, it is shown that a Battle Nizer is a mix of technology and organic components. The second form of the Battle Nizer is a metamorphosis brought about by Rei's growth in power. This would mean that they are dependent on the owner Reionics' energies as shown by the Battle Nizers of defeated Reionics are never shown to be unusable.
- Out of all Battle Nizers, only one existed for Giga Battle Nizer, as this was destroyed upon Beryudora's defeat then reconstructed by Reibatos and only to be return to Belial's hands.
