Tsuburaya Productions had registered four new trademarks which seems to be related to Ultraman Trigger.
1. MetsuOrochi 2. MetsuOhga
MetsuOrochi seems like the new evolution of Maga Orochi which we have seen in Ultraman Orb. Maybe it comes in similar evolution categorization as Horoboros becoming Metsuboros
MetsuOhga looks like completely new monster.
The other two trademarks looks like new GUTS Robo Mechas.
1. Mecha Musashin - Kinda reminds me of Musashi / Ultraman Cosmos 2. Barigailer
