Ninja High School #157 (2008)

GOLD DIGGER CROSSOVER! Determined to cut down on local crime, Mayor Arnie, the gun-toting, armor-wearing, sword-wielding, vigilante badass, decides to form a young superhero team. But when their public displays of heroism draw the attention of a wide variety of villains, Gold Digger's Agency Zero has to step in! Teen superheroes, WW2 supervillains, and covert government agents collide in a massive, super-shutdown free-for-all! It's a global-civil-war-behemoth, break-the-internet-in-half, one-issue mini-event, after which NHS will never be the same (more or less)!
