Here are the scans of Ultraman Orb Origin. He uses the powers of Orb Caliber to transform into this form and also to fight. Orb Caliber can perform four finishers.
Great Magus Beast Magaorochi who was defeated was absorbing the energy of the Earth. He continued to grow and transformed into Super Great Magus Beast Magatanoorochi.
Hyper Zetton Deathsythe is going to be revived as Hyper Zetton Deathsythe Reserver. This time Ultraman Orb is going to fight as Orb Origin.
Metron Seijin Round Launcher will appear to defeat Jugglass Juggler but Gai will stop him by transforming into Ultraman Orb. This Metron Seijin has Gatling Gun on his arms.
Ultraman Zero is announced to appear in Ultraman Orb between Episode 18 ~ Episode 22. Probably Ultraman Zero is the only Ulraman that had appeared in all three series → Ginga (Ginga S), X & Orb.
Probably his appearance has something to do with Ultraman Orb Origin evolving to Ultraman Orb Trinity using Orb Slugger.
