Okay, so... Lex kidnapping Krypto and turning the dog into a human wasn't part of Clark's plans. Yes, that's right.

Now Clark, Supergirl, and the entire Justice League were facing a humanoid version of Krypto—albino, short, cute, wearing Clark's uniform and cape, sporting the collar with the Super symbol, and worst of all: still having the ears, tail, and senses of a dog. Everyone seemed confused (though Bruce looked exasperated) while a very curious human Krypto stared at them all.
