A Piercing Screech

Ridley reveal trailer is a trailer for Super Smash Bros. Ultimate shown at E3 2018 on June 12, 2018. As indicated by the name, it gave the surprise reveal that Ridley will be a playable character in Super Smash Bros. Ultimate after years of fan requests.

The trailer, after showing the four-line Smash logo, begins with Samus Aran, Mario, and Mega Man crossing a narrow bridge over a chasm in a dark mechanical area. Each of them are looking around cautiously. Suddenly, an unseen figure manages to knock away Mega Man, with there being a flash of red afterward as it shows in silhouette Mega Man being impaled in the chest. Then Mario gets picked off in short turn by the same unseen figure as soon as he looks the other way, knocking his hat off in the process, with there being another flash of red, and it showing the figure crushing his head in silhouette. Eventually, only Samus is left. She feels unease as she senses that someone is stalking them and quickly turns around to aim her arm cannon, only to find Mario's discarded hat. Soon enough, however, the bridge starts quaking, and then the figure reveals itself to be Ridley by bursting out of the bridge from underneath, with Samus being knocked back in an apparent state of shock as Ridley proceeds to roar viciously, with Ridley then promptly grinning as he twirls Mario's cap on his finger.

It then cuts to some gameplay for Ridley that is showcased, including several of his smash moves before ending with his using his Final Smash on Samus. After showing the title of the game, it then cuts to what is presumably the aftermath of the Final Smash, where Ridley is watching triumphantly the burning wreckage of Samus's ship, only to then notice that Samus is still alive, with Samus jumping out and then becoming Zero Suit Samus as she jumps down at him with fury on her face as it fades out.
