Is there a “Super Smash Bros.” movie on the horizon? It sure seems like that’s what “The Super Mario Galaxy Movie” is building up to, with the surprise announcement Thursday that Fox McCloud, of the “Star Fox” and “Super Smash Bros.” video games, is joining the film.

Fans have theorized that space pilot Fox could be in the movie after a blink-and-you-miss-it appearance in a previous “Super Mario Galaxy Movie” trailer. Now, it’s all coming true. No voice actor has been announced for Fox yet.

Fox was first introduced in the 1993 action-adventure game “Star Fox” on the Super Nintendo Entertainment System and later in “Star Fox 64,” “Star Fox Adventures,” “Star Fox: Assault,” “Star Fox: Command” and most recently 2017’s “Star Fox 2.”

However, many gamers know Fox from the fighting game series “Super Smash Bros.,” which brings together characters from across Nintendo properties and beyond to beat each other up. Fox was one of the first fighters in 1999’s original “Super Smash Bros.” on the Nintendo 64, and he’s been in every iteration since — just like Mario, Luigi, Donkey Kong, Yoshi and more. Fox’s co-pilot Falco was brought in for “Super Smash Bros. Melee,” and the villainous Wolf was added in “Brawl.”

“The Super Mario Galaxy Movie” previously teased one of the Pikmin used by another “Smash Bros.” character, Captain Olimar from the “Pikmin” Nintendo games, in a teaser — further fueling the “Smash Bros.” synergy. Could the space bounty hunter Samus appear next, or perhaps the speedy racer Captain Falcon? Fans will have to wait until “The Super Mario Galaxy Movie” hits theaters on April 1.
