How does Krang stay alive?
 

He lost his body. He has no stomatch. Doesn't he need to eat and go to the bathroom? Sure the 4Kids show sort of did the same thing with Baxter. But at least than you could assume his robot body had some sort of life support system. Krang is able to live outside his body.

He's from a different dimension, no one could begin to understand his races' physiology.

He's a disembodied brain with a mouth, what more is there? Admittedly, though, the food issue has bugged me for a while. If one wanted to, could say he could eat via nutrients or akin to IV bags, but that's overthinking it. The rest is MST3K Mantra time, except he does make the occasional food metaphor, like he wanted to do with the Turtles in the first Metalhead episode, right? Just because he can't eat or seem to eat on-screen anymore doesn't mean he doesn't think about it, on occasion.

I don't think this is a hard question to figure out.

Just ask yourself "How does the human brain stay alive and alert?"

The answer should be self-evident:

Caffeine.
:tparty:

So your saying his race has there stomatch and anus inside thier head?

Of course. It would explain a lot, like does he ever sleep? Didn't he admit to having a nightlight in "Bye, Bye, Fly"? Heh.

If he ever did conquer New York City, he'd own all the coffee cafes. Now, if only someone can do the Starbucks logo with Krang's face. Get to work, graphics people.

And, let's not talk about Krang's anus. Please. He's fueled by outrage and frustration by the Turtles beating him -- that keeps him alive.

Edit: But to be serious, for a moment, the Krangezoids episode might be the closest we'd get to canon with Krang's body. The Krangezoids looked almost reptile-based. Could play on that, and how the clones preferred a more warmer climate, which could but doesn't necesarily indicate a more cold-blooded form. Or, at the very least, that form looked like a predator, which could imply a preference for meat.

Yes, I'm speculating, but I don't know how to answer this properly, either. Heh.

I'm sure who ever took away his body made sure he'd survive to prolong the suffering and shame.

Science, or a Wizard did it.

I was just going to remind every-one this is a cartoon

I couldn't have said it better myself!

NO UH!! :tgrumble:

Sheesh, next thing you know we'll be trying to figure out the physics of Bikini Bottom!

Why not ask Peter Laird on his blog to see he answers about what he theorized an utrom would do for food/bathroom needs? That answer would be the same for Krang.

Now why didn't I think of that?

He ate popcorn in Turtles Forever, but I think oldmanwinters is right-on: caffeine!

exactly right on

No it wouldn't. Krang lost most of his body the Utroms didn't.

Tomato/tomato, ketchup/catsup. Krang is still based on the utroms.

based off, but different species (save the daily strips) The utroms probably got a fully usable anatomy, since they are naturally sentient space squids with faces.
