If you're not careful, you'll give him an upper case head

He’s Darren Grey, King of Roguelikes. He’s beaten more Roguelikes than actually exist. He’s the guy that ASCII dragons tell their children about so that they eat up all their villagers and grow up to become upper case. I’ve met Darren Grey, and he looks exactly like Mr. T except all the gold chains are actually amulets of Yendor.
