Based on the poster shown, here's are the list of voice actors, but for those who are already associated to the Ultra Series, I gave them several of their past roles to be noteworthy of:
- Mamoru Miyano (Ultraman Zero)
- Takuya Negishi (Hikaru Raido/Ultraman Ginga)
- Kiyotaka Uji (Shou/Ultraman Victory)
- Koichi Yamadera (Gridman Anime's Takeshi Todo, The・Ultraman: Jackal vs. Ultraman's Zoffy, Melos and Demon King Jackal)
- The trio comedian Jungle Pocket, consist of:
- Hirohisa Ota
- Shinji Saito
Since we have an Alien Gapia, Alien Guts, Alien Temperor and Alien Hipporito, its up to you to think of it.
Also, since the Jungle Pocket is a three people group, they can't be considered as a Manzai (Boke-Tsukkomi pair comedians).
