Mecha Sally Audition is an audition video for Super Smash Bros. Crossover. Similar to Metal Mario Audition, this video only features Mecha Sally to be auditioned for, due to her role as the main antagonist of Season 34.
- Like Audition 3: Good Vs. Evil, Mecha Sally Audition gives more information about the character being auditioned for.
- The theme used in the audition video is the metal remix of Ridley's theme, due to the fact that it is also the theme of Team Metal.
- Unlike most audition videos, the music does not start right away in Mecha Sally audition. This is done in order to create build up.
