The ground shakes. Anxiety fills the air. People scamper in panic on the streets. Gigantic aliens are invading Earth, and it seems that humankind is forever doomed. But wait — what's that up in the air? It's a bird, it's a plane, it's — Toilet Bowl Man? You better believe it. And, along with his squad of fellow heroes, he's our last hope of flushing the invaders away. With the world on the brink of disaster, it's up to the strangest and unlikeliest of heroes to swoop in and save the day. However, no individual power is enough to do it alone. That means, from Bonzai Man to Vending Machine Man and every other man in between, the world's wackiest superheroes must come together and give alien scum a taste of Earth-style teamwork.
