Can anyone explain what happened?

Chuck Norris (the real life dude) died recently,

The post is referencing a well-known song titled “The Ultimate Showdown of Ultimate Destiny”, in which Chuck Norris (as a cartoon character, the whole song is animated) descends from the heavens, beats up Indiana Jones, kills Batman, but ultimately loses to a bunch of characters ganging up on him, including every single Power Ranger. In the end of this bloody battle, only one was able to come out alive: Mr. Rogers, in a blood-stained sweater.

Specifically, it was Gandalf the Grey, Gandalf the White, Monty Python and the Holy Grail’s black knight, Benito Mussolini, the Blue Meanie, Cowboy Curtis, Jambi The Genie, Robocop, The Terminator, Captain Kirk, Darth Vader, Lo-pan, Superman, every single Power Ranger, Bill S. Preston and Theodore Logan, Spock, The Rock, Doc Ock, and Hulk Hogan
Don’t know about the animation. Thanks a lot for the explanation!!!
