Crazy Character Ideas?, GM is running a Freaks campaign, I need ideas Options

[Hound]

So my friend is running a Freaks campaign (basically meaning that all the characters are supposed to be weird or whatever in some way and nearly all of the optional/restricted rules are allowed.) In addition to normal option rules, she wants each character to have some kind of special "Artifact" which should be based on rules she makes up. Basically the players decide on a concept for their artifact, then they sit down with the GM and work out the rules.

Now, normally I love making characters and can come up with a million, however, I have a strong tendency towards awakened characters usually and most of the group (3/4 so far) is comprised of awakened characters this game. So I was trying to think of a good technology freak and artifact idea. The problem I keep running into is that it's easy for me to make a tech freak that is powerful, but difficult to make one that is really that interesting, specifically with respect to a special/game-changing item. The only one with potential that I've really come up with so far is a cyborg character in a humanoid body, with the body being my artifact. Problem is I can't really think of anything that character could do that a cyber-samurai would be unable to do. It's powerful (4 base IP, innate armor) but I don't think it will be that interesting.

So, do you guys have any crazy character ideas? Or possibly ways to make a cyborg more interesting?
