The surprise reveal this week of Deathstroke footage by Ben Affleck not only sparked speculation about the DC Comics antihero's role in Warner Bros.' "Justice League" and beyond, but apparently also stoked the flames of the decades-old fan debate involving similarities between the one-eyed assassin and a certain Merc With a Mouth.

Right on cue, Deadpool co-creator Rob Liefeld popped up to address the differences between the two characters -- this time with the help of visual aides.

Appearing on Nerdy Pop, Liefeld acknowledged, "I have loved Deathstroke my entire comic book-collecting career," adding, "He's a great character. He deserves to be loved on his own merits." What might those be? Well, the high-energy artist came prepared, with action figures and a breakdown of "How Your Deathstroke is Not a Deadpool, in Five Easy Steps."

Among the differences, Liefeld points to Deathstroke's chain mail, the differences in costume color schemes, and, um, buccaneer boots and gloves. However, there's no mention of the similar names, Slade Wilson and Wade Wilson.

"I got skin in this game, I know," Liefeld acknowledged. "But, kids, this is what I see with my own two eyes. [...] Deathstroke is a great character. He is an awesome, awesome character. They are nothing alike. So, DC bros, I just came at you, OK?"
