Four different LoRAs to represent the four different eras of Ultraman!
Showa: Ultraman - Ultraman Zearth (Technically the last three Ultra, Great, Powered, and Zearth, featured are in the Heisei era, but 2 were made for Western audiences and one was movie-exclusive, so in a way, it's like how Shin, ZO, and J were lumped in with the Showa Riders despite them being made in the Heisei era)
Heisei: Ultraman Tiga - Ultraman Zero
New Gen: Ultraman Ginga - Ultraman Rosso/Blu
Reiwa: Ultraman Taiga - Ultraman Blazar
