Junkpile is your classic brick with all the norms they have, big strength, resistance to damage and plenty of bad attitude. Though I do seem to recall Junkpile having more attitude than most other people in the world of 2099, he really reminds me of something of a redneck with powers and a bad outlook.

His actual powers were pretty different, he could use metal to rebuild his body from injuries. Clearly he went crazy with his healing ability cause when the series opens up over 90% of his body is metal. As a result of the super-strong metals commonly found in the time Junkpile has superhuman strength & resistance to injury. I mean this guy is tough enough to take on pretty much the whole team and keep the fight at a standstill, they're playing it defensivly against him and such so that he can't touch them and they can't generate enough damage to get through his metal shell over his body.

But I do like how he worked out, a over-pointed PL that's difficult to damage unless you go mental or magical powered against him. Seeing as how most of the characters were PL 8 or 9 that caused them some trouble dealing with him and only guys like X'ian with his disintergrating hand or Skullfire with his boosted blast could really put a hurting on Junkpile.
