Lockjaw is the underdog (pun not intended), but he could pull off a win. He's shown to do stuff other than tleporting, it's just that the teleporting is the most popular. For instance, when he had a door gripped in his jaws, Ben Grimm COULD NOT pull it open no matter what. So that shows some decent strength. He's also shown the use of forcefields a few times. I say Lockjaw teleports Krypto away and rematerializes him in solid granite.
Believe it or not, Krypto is much smarter. He's not a regular dog with regular intelligence. He's a perfect designer breed with uber-intelligence. In the War of the Worlds saga, he was rescuing people, deactivating bombs, stopping floods and volcanic eruptions.
The only way Lockjaw can win is if he manages to teleport Krypto somewhere. However there's a thing called speedblitz.
HAHAHAHA....man these DC Marvel threads r always so similar. Krypto's intelligence is pretty obvious. I'm not sure if they've ever revealed how smart lockjaw is but its implied that he's more like another inhuman than just a dog. Lockjaw also probably has class 100 strength, and he's one of the better teleporters behind guys like Pip.
