I send the Vision (from Marvel's Avengers comics) to eliminate your defenses. He can become intangible so your defenses are moot and he easily disarms the pylons. As for the worms, I have a bunch of giant robots take care of them.

My defenses include Vision, numerous giant robots, the cast of Golden Girls (who would like to hear them drone on? I have earplugs and Vision can disable his audio sensors if they bug him. The robots? Same as Vision) and a herring.
