There is so much wrong with your post that I don't even know where to begin, so I'll start at the end.
No one will take this seriously.
For starters, you're trying to copyright a meme that originated on 4chan in 2009, and are doing so over a year after
Super Meat World was released, as a free
addition I might add, to the game.
Also, the "forever alone" character you claim to own the copyright to is not used in Super Meat Boy. The use in question is not of that character, but Doctor Fetus is drawn by Edmund McMillen with a face based off of the Forever Alone guy. The art is original, and the character is too.
I'm no expert on United Kingdom copyright law, but I don't have to be to know that if for whatever reason you manage to successfully take this to court, you would lose. If not by ruling, then at least by legal fees.
Now stop wasting ours, and attempting to waste Team Meat's, time and scam for royalties somewhere else.tl;dr
