- "Think again, Alisa! You're the one that closed your eyes!"
- — Zekrom, after Alisa falls asleep.
Zekrom is the legendary Deep Black Pokémon. Concealing himself in lightning clouds, he flies throughout the Unova region. He creates electricity in his tail. He never creates thunderstorms when he visits Rockoland due to its invulnerable sunny weather. His friends are the female Tekken: Blood Vengeance protagonists - Alisa Bosconovitch and Ling Xiaoyu, but his best friend is Reshiram.
While Reshiram is the Alisa's Adventures in Rockoland counterpart to Lee Chaolan, as he is very mature, Zekrom is the Alisa's Adventures in Rockoland counterpart to Ganryu, because he can be very harsh and very rude to most characters, especially Crash Gordon but never his best friend Reshiram. Zekrom's harsh personality would be carried over to Barney and the Rocko Squad and Xianghua in Rockoland as the personality for Monstar and Setsuka, respectively.
John Leguizamo is Zekrom's voice actor in Alisa's Adventures in Rockoland.
