The final boss? ROGERS CABLE (or any other draconian internet provider).
First you have to survive wave after wave of impatient, dead-end call waiting machines trying to call you an idiot for not pressing the button fast enough and ending the call or misinterpreting everything you say. Then you would be battling some disinterested indian with a thick accent over the phone in order to ascertain why your internet abruptly stopped. Yes, yes. "Did, sir, you go, sir, and switch it on and off, sir? You need, sir, to make sure your computer is on, sir, and that there is not a darkened screen, sir; can you do that for me, sir? Now open up your stove, sir, and slam your head in it repeatedly. I will tell you when to stop, sir."
More powerful than LOLCATS, Wikileaks, trolls, Star Wars Kid, Leeroy Jenkins and even spam e-mail... put together! It could also double as the final boss of a telephone-related adventure, so clearly double evil.
