Marvel Adventures Iron Man, Issue 8

Ambushed by the villainess Jolt, his armor ruined, Tony Stark finds himself trapped in an isolated village run by folks who have chosen to live a peaceful, agrarian 19th century existence...without any technology. With Jolt hot on his trail, what's a tech-dependent hero to do? That's right: hole up in the blacksmith shed and hammer out an all-new suit of STEAM-POWERED ARMOR! Aw, yeah.
