Vargskelethor's Hardcore Friday Super Metal Almost Criminally Violent Ultra Swedish Meatball Royal Rumble MASSACRE!, or simply shortened as VHFSMACVUSMRRM, is a M.U.G.E.N screenpack made by Brergrsart in tribute to Vinesauce Joel. The screenpack includes Joel himself as a playable character, complete with other characters that appear or at the very least related and/or referencing to his previous streams, including Bootleg Felix the Cat, Bulk Bogan, Jotaro Kujo, Skeletor, and so on.

To put it simply, it's a frickin' Vinesauce Joel fighting game, complete with shout-outs and nods from his previous streams and many more. The characters consist of Joel himself, which is a palette swap of Michael Roa Valdamjong with his moveset referencing his previous streams, some characters that Brergrsart himself has created for the game, and other characters from various fighting games (with credits to the original authors, of course) related to Joel's previous streams, including four bonus bosses that you can encounter during the arcade mode.
