#4: Warp Portal
As you will notice throughout this series, the Turtles apparently speak a lot like Bill and Ted (from "Bill and Ted's Excellent Adventure", of course).
If you notice, Krang doesn't do much. This is because: as cool as his walker is, it's a bitch to put together and make it look just right. So I didn't bother much.
It's always a thing doing any comic -- any plans I may have for something are limited in real world application. Often times I find myself altering things or changing how things are going to go (here and in the rest of the comic) based upon one or two small (and yet key) details that occur halfway into the comic making process.
So instead of having Krang and Shredder both go back, as I originally intended, here I just send Shredder. More on this later, as it becomes informative...
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
