G-Man: Cape Crisis #3

Synopsis

Glendolf tells the boys that they have to recover all the flight bands to preserve the magic that gives G-Man and Great Man their powers, or a catastophe could occur. While they are recovering a band from a supervillain who's fighting the Savage Dragon, Great Man discovers a way to sell even more flight bands (and he's raised the price to $10,000). G-Man and Great Man fight over the flight bands, but when G-Man's cape gets torn there is a terrific explosion, which seems to have killed Great Man!
