Here's page 29 of Fusion #4, and we get some insight into how X-Pletive's powers work. Not mentioned here (but will be referred to later) is the fact that X-Pletive also has extremely dense bones, which are able to withstand standard gun attacks.
Seriously: If what he said was the case, he should not say a single ######## #####word now, where he doesn't need his powers at all. If he got so used to ######## that he can't stop anymore, it would not activate his powers anymore. Also, explaining the nature of one's powers is one thing, but explaining en detail how exactly they work... idk.
Unless he's ####### lying about it - but why should he make up such a story, then?
