1. Starro The Conqueror
Who? Its a giant intergalactic starfish that uses smaller starfish as mind-control masks. Thats it. Thats the reason why the Justice League joined forces in the first place. Im going to let that sink in for a minute.
Why We Won't See Him... Making its debut in Brave and the Bold #28, Starro the Conqueror began its conquest by endowing three regular starfish with its alien abilities before setting up shop in a place called Happy Harbor. At this point, I couldnt really fault anyone if they confused Starros plot with a bad Disney animated feature. Despite its underwhelming appearance, Starro gave the Justice League everything it could handle. In fact, it was a random b-character, non-powered human Snapper Carr, who came up with a plan to dump quicklime all over the creature, and thats it. You know, just dump this incredibly common chemical on the giant intergalactic mind-control starfish over in Happy Harbor. Imagine Cthulhu without the awesome powers, or the boundless evil, or the insurmountable size, or any other good or interesting thing. Thats Starro the Conqueror.
