I've unbanned you. In the future, perhaps you may wish to excercise more caution - what did you think would happen when you sent a message that included that phrase, after you'd seen people be banned for using it?
It was called Super Smash Bros. Brawl Crossover but now I want to change it to Need For Speed Underground because the story doesn't appear to be like Super Smash Bros. Brawl as it is rather cars, racing, action, and adventure
Ok. Then go to the wiki you're talking about, write Special:Contact/wiki-name-change after wiki/ in the URL and send the contact form with what you have just said. Fandom staff usually don't do these kind of things if they haven't been sent to the contact form. That way they can answer faster, it is more private and they have clear evidence about what the user asked for.
Well, I will become a bot someday, but what bot do you plan on making? And if you want to make a chat bot, then please see this user. If you want to make an editor bot, then you can just use AutoWikiBrowser.
