Any description of this Lex Luthor Armored Up T-Shirt would probably miss the genius at work here. Might as well use blue kryptonite to try and trap Superman but that's not working. Just look at the colors man! The retro Battlesuit from the future of science! But most of all look into Lex Luthor's eyes. Do you see that? That's why you build a battlesuit with no helmet not so you can get punched in the face by Superman but so that caped clod can see your face when you beat him! Pull out your red-sun ray gun and power up the kryptonite shields. Lex Luthor is on the loose! Oh forget all that this simple 100% cotton black t-shirt featuring Lex Luthor the most brilliant villain on the planet makes me smile. It's a classic.
