I used to think he was just a Ninja with a smart ass attitude, when i was a kid reading comics. I remember him getting blasted in the back by this chick with a black dot around her eye, something to do with Cable.
But a friend of mine showed me his issue in that arc where aliens are invading the world, i don't recall the name, and it was hilarious the way he was aware of where he was, and the way he managed to kill every alien the space ship he was in by doing some rather clever things but that were funny and stupid in a sense.
I became a fan with that issue, downloaded a bunch of comics of his and sure there's a ton of stinkers, but in a time where i no longer read comics, he made me read again and that was fun.
