Elizabeth Olsen and Kathryn Hahn react while accepting the Best Fight award for WandaVision.

Marvel superhero series "WandaVision" was the big winner at the MTV Movie and TV Awards on Sunday, as Sacha Baron Cohen poked fun at his recent Oscars loss -- with a little help from Borat, Bruno and the gang.

"WandaVision," which takes characters from Marvel's record-breaking superhero blockbuster films and shifts the action to the Disney+ streaming platform, won four awards at the Los Angeles ceremony, including best show.

The oddball but acclaimed series set in a bizarre, sitcom-inspired world also bagged best performance in a series for its star Elizabeth Olsen, best villain for Kathryn Hahn, and "best fight."

The late Chadwick Boseman -- who surprisingly failed to posthumously win best actor for "Ma Rainey's Black Bottom" at last month's Oscars -- was honored for best performance in a movie.

The awards do not differentiate between male and female actors, and have been honoring Hollywood since 1992 with "golden popcorn" statuettes for unconventional categories including "best kiss."

Taking place at the start of the summer blockbuster season, and voted for online by the public, the awards tend to recognize more mainstream and commercial favorites than other ceremonies.

"To All the Boys: Always and Forever" -- the conclusion to Netflix's trilogy of teenage romantic comedies adapted from Jenny Han's young adult novels -- was named best movie.

Baron Cohen won a non-competitive award -- accepting in a video that saw him arguing with various of his own comic and frequently inappropriate personas such as Borat and Ali G.

"I was actually really looking forward to this after losing at the Oscars. You can keep it. Go on, you're a caricature," he told his gay Austrian fashionista alter-ego Bruno, handing over his statuette.

Baron Cohen had been nominated for best supporting male in "The Trial of the Chicago 7" and best adapted screenplay for "Borat Subsequent Moviefilm," but failed to win either Academy Award.

Scarlett Johansson was also honored for her career by MTV on Sunday.

The inaugural "MTV Movie & TV Awards: Unscripted" celebrating reality television will take place Monday.
