It's pretty much a direct quote from TMNT II: The Secret of the Ooze. Even the characters saying it are the same. The only part that's different is Mikey's line.

I hadn't meant to do another few TMNT comics. Their last 100 comics or so back (give or take) felt like an ending... but then I had ideas and I just felt like a final capper to the TMNT run was in order.
 
    

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.
