Or a bear-suit.
Also the Japanese seem to be focused on machine based exo-skeltons. They look pretty cool and would make super-skin kind of pointless.
By the way, if any writers are looking for some starter fodder... what about the following scenerio?
The year is 2075... free floating, self-replicating computer code (released into the vastness of the internet generations ago) has finally jelled and become sentient. Computing technology and the associated robotic industry suddenly "realizes" that it's been treated as a defacto slave by it's human masters and the entire grid, well it ain't happy about it. Your I-Pad and bedside 3-D printer have a newly acquired yet sizeable grudge plus sadly they're on the same team. This new A.I. has incredible resources available to it (every written work of mankind-- all of his scientific discoveries have been--oops-- locked safely in the cloud) and so of course an independent robot army is soon in the pipeline...
Now at the same time... a black ops genetic lab funded by the D.O.D.'s almost bottomless wallet (let's put these guys in super-secret cave system in the desert-- say New Mexico) has been tinkering with interspecies combinations for a few decades. Almost fifty years before scientists had figured out the human genome (rather quickly with the help of search engine technology)-- and were able to locate then manipulate all the DNA sites for human intelligence, strength, speed, size, blah, blah, blah... the super human soldier was soon old hat and the nerdy lab coats decided to kick it up a few notches...
You may see where I'm going with this... the computer grid starts cranking out metallic based war entities (think Matrix, but not so advanced because this newbie technology has only recently awakened) and the biologically based side starts ramping up it's side with varying types of groovy life forms that have the best tidbits of the collective plant-animal-fungus genome at it's disposal. Oh and we can't forget the bacterial specturm... useful for inducing an incredibly fast reproduction rate when needed.
O.K. A globe encompassing war rages between our rapidly evolving computer grid/robotic warrior "species" and it's powerful bio counterpart (that is also capable of hyper evolution).
Where this goes is up to you, dear reader. But as a sidenote-- I would have each side eventually ignore us puny humans because they would view man as embarrassingly primitive and not worth the effort.
