This is what I think what would happen in the series finale of MLP:FiM. Before Grogar was about to stomp his hoof, he realized his Gauntlet didn’t have the Elements of Harmony, and Twilight, who has bruises and scars (let’s say they are on the other side of her face). With her gaultnet powering up, she stomped her hooves and a huge explosion of light, the size of the Empire State Building beamed the almost dark sky, causing all of the villains such as Lord Tirek, Queen Chrysalis, Mean 6, Storm King, and the rest of the villains that didn’t reform to disappear into dust particles. Then Grogar disappeared last.
