Bandai Namco recently gave word on a roster update for Super Hero Generation, in addition to the character list previously announced.
If you are not familiar with Super Hero Generation, it is a new entry in a Gundam, Kamen Rider, and Ultraman crossover series. I am pretty sure these just announced characters will be included in-game and are not DLC since the game’s release is still pretty far away:
Arios Gundam (from Mobile Suit Gundam 00):
Ultraman Hikari (from Ultraman Mebius):
Gundam Banshee (from Mobile Suit Gundam Unicorn):
Phoenix (from Kamen Rider Wizard):
Evil Tiga (from Ultraman Tiga):
Super Hero Generation is currently set to release exclusively in Japan on October 23.
