- Role Reprise: In BONUS EDITION, Susume Kurobe and Kohji Moritsugu return as Ultraman and Seven.
- In 2, Ryu Manatsu reprises his role as Leo.
- Finally, Tetsuo Kurata, Renn Kiriyama, Shu Watanabe, Hiroya Ishimaru, and Takuya Negishi all provide new lines for Black/RX, the Shotaro half of W, OOO, Taro, and Ginga.
- Talking to Himself: Ultraman Zero and 00 Raiser/00 Qan[T] are both voiced by Mamoru Miyano. This fact was likely reason enough for Zero and Qan[T] to get a Combination Attack in 2.
