Check out our annual wrap up of great Halloween costumes donned in 2021 by your favorite UFC and MMA fighters.

Happy Halloween, Maniacs!

It's October 31st once again and you know what that means: it's time for our annual rap rap wrap up of all the MMA fighters and their awesome Halloween costumes. This year it looks like it's about 50% parents with their kids and 50% adult costume party business, which we're definitely cool with.

Let's kick this off with the UFC's official happy Halloween message, delivered by Forrest Griffin (and featuring appearances by Dominick Reyes and Tatiana Suarez.

The winner of this year's unified family Halloween costumes has to go to Max Holloway and his "Blessed" clan for their inspired Demon Slayer: Kimetsu no Yaiba costumes.

We think Cris Cyborg wins sexiest costume this year, and we're just as shocked as you are.

Jon Jones dressed up as a sociopath, and wearing a Michael Myers mask.

And Sam Stout only comes in second to Max Holloway on the family costume contest because he's retired. But damn, that is a fine Addams Family.

Angela Hill is a spot on Sho Nuff from The Last Dragon. It's just a shame she didn't get Alex Caceres out to be Bruce Leeroy with her.

Tim Kennedy is the manliest man we know that's always willing to get silly with his kids.

Kay Hansen gives us the ol 2 for 1 special.

And Megan Anderson looks like she's brewing up some trouble with her Hocus Pocus costume.

Roxanne Modafferi goes Nintendo.

And Joanne Calderwood channels her inner unicorn with coach / husband John Wood.

Gabi Garcia looks very capable of beating your skull in with a baseball bat.

And Arianny Celeste goes deep with a solid Horror movie cut, playing Bride of Chucky.

Jessica Penne is some sort of goth Minnie Mouse?

And Georges St-Pierre shows us the way.

Make sure to share any costumes from MMA fighters and personalities we missed and we'll make sure to update this post!

Update! Round 2!
