Now, if you compare this photo to the one above, clearly there are a few differences right off the bat. First, you can tell that Wendy's doing her nails differently, and that Marvin got rid of that awful haircut. Also, Wonder Dog turned into the Hound of the Fucking Baskervilles and ripped out Marvin's sternum, murdering him in the process. Apparently in this version, Wonder Dog was invented by an evil mastermind to use his adorable lovability to win his way into the hearts of the Teen Titans immediately before tearing them out.
This character reboot is a rare case that seems like it was brought on for absolutely no one. Who would want this? Nostalgia-loving fans of the original dog will be heartbroken to see a piece of their childhood distorted so profoundly, and the kids who actually read Teen Titans will be traumatized beyond pissing their pants. They'll have transcended straight on through to a new level of fear wherein they piss their own souls.
Why would anyone want that?
