Man, I just don't know how I feel about this video. Let me just start by saying this: it's seriously grim. It's a little bit offensive in a number of ways, but it also has moments of hilarity. Let me just preface the video with that disclaimer: this has some brutal moments and some slightly sexist/racist moments. But it's still kinda funny. It's like Benny Hill or something.
With that, please allow me to present Mario getting really angry at characters from other games and other consoles totally moving in on his turf. Watch as he brutalises them one by one in increasingly more violent ways.
The way he disposes of Sonic is particularly cringeworthy. I'm sorry you had to go out like that buddy.
