Astro City, The Voice of the Turtle, by Kurt Busiek

The story of the turtle seems a little out of place, though I can understand why it exists. Astro City has been in the middle of a series of books about the steel jacketed man, a convinced criminal who is trying to get his life together after being released from prison. A good story but this is a welcome respite from the general darkness of that story.
He used that new power to become a sort of robin hood stealing from the rich but instead of giving it to the poor he gave it all to his girlfriend. In return she helped him upgrade his suit by gathering together the power suits of a criminal organization but soon he discovered that he wasn't in Robin Hood he was in Macbeth and she was simply using him for her own gains.
She used the suits that he had helped repair to chase him and eventually he was forced to flee to astro city. The story then comes around to the Steel jacketed man as he helps the turtle to defeat the men chasing him under the assumption that they are the ones he has been trying to stop.
