I'm pretty sure the bloated stats on the Wolf stem from Pgrs111Magen's liking of The Wolf on YouTube. As for the Raging Demon, I'm pretty sure it stems from the early days of Wlanmania's career, when he fealt that everyone needed a Shun Goku Satsu for some reason.
I'm not sure why Pgrs keeps shitting out characters like a guy who ate rotten Taco Bell, but he seems to be unstoppable.
The Wolf, despite his overpowered stats and roughly 20 power bars, tends to do jack shit. A character with plenty of projectiles or assists could keep him away. Anyone with a OHKO would flat out screw him over. Other cases, the overpowered stats are a major part of why they suck (Omega Rotom and Josh Geary's Barney edit, for example). Of course, I also have zero experience editing characters.
And I'm pissed about the Dragon Claw spriteswap as well.
