- "You see here, my best friend Zekrom is always being harsh. Just like Ganryu in that one movie!"
- — Reshiram explaining how his best friend Zekrom acts during the series
Reshiram is the legendary Vast White Pokémon. When Reshiram's tail flares, the heat energy moves the atmosphere and changes the world's weather. Since Rockoland is always sunny, Reshiram's tail flaring is useless against Rockoland's atmosphere. Reshiram is a good friend to Alisa Bosconovitch and Ling Xiaoyu, the female Tekken: Blood Vengeance protagonists, but his best friend is Zekrom.
While Zekrom is the Alisa's Adventures in Rockoland counterpart to Ganryu, as he is very harsh and very rude to most characters, especially Crash Gordon but never his best friend Reshiram, Reshiram is the Alisa's Adventures in Rockoland counterpart to Lee Chaolan, because he is very mature. His mature personality would later be used for Dora Marquez's personality in Barney and the Rocko Squad and Roger-Roger's personality in Xianghua in Rockoland.
Ewan McGregor is the voice actor used for Reshiram during Alisa's Adventures in Rockoland.
