Nintendo has announced that Martinet, who rose to a new level of fame with 1996's Super Mario 64, is leveling up to the role of "Mario Ambassador" which apparently means he will not voice the character in the upcoming Super Mario Bros. Wonder.
In its initial statement, Nintendo said Martinet will be "stepping back from recording character voices for our games." However, Martinet will "continue to travel the world sharing the joy of Mario and interacting with you all."
When asked about whether Martinet would voice Mario in the upcoming Mario Wonder, Nintendo told GameSpot, "While Charles is not involved in the game, we're excited to honour his legacy and contributions, including looking ahead to what he'll be doing as a Mario Ambassador."
There is no indication of who will replace him. Nintendo said: "Character voice actors will be credited in the game credits, so please wait for the game to be released." Nintendo also stated that it will have a "special video message" to share from Mario creator Shigeru Miyamoto and Martinet to come "at a future date."
It added, "It has been an honour working with Charles to help bring Mario to life for so many years and we want to thank and celebrate him."
Martinet also voices Wario, Luigi, Waluigi, Baby Mario, and Baby Luigi, among others so it looks like the cast list is wide open.
