Imagine two of TV's toughest men: Walter White and Rick Grimes. Both of these characters hail from AMC TV; White, courtesy of Vince Gilligan's "Breaking Bad," and Grimes, of course, is the main dude in Robert Kirkman's "The Walking Dead." 

Unsure of who these two characters are? Then, like the dude in that Geico commercial, you must've been living under a rock. Walter White, aka Heisenberg, is the don of Albuquerque, New Mexico. Best known for cooking up ultra-pure, high-grade methamphetamine and stomping out the competition with his devious schemes, no one is more feared. 

Meanwhile White's competitor is smooth talking country boy Sheriff Rick Grimes. While White does things on the wrong side of the law, Grimes is the most moral man on TV. Yet, the zombie apocalypse has made him a bit bitter. Nowadays, Grimes is best known for splattering zombie guts all over the Southern United States. 

Combining these two bad boy Alpha males would make for a great show. Luckily, someone decided to make this crossover possible. Leave it to Epic Rap Battles of History to set up this must see, head-to-head vocal extravaganza. But before we get any further, just check out the full "Rick Grimes vs Walter White" ERB of History Season 3 video below: 

That was pretty epic (pun obviously intended) right? Well, make sure to voice your opinion on the YouTube comments page. Whoever wins the rap battle is bound to get another shot at taking down another MC... Or perhaps you found both men to be great MCs? Either way a Walter White-Darth Vader battle would be amazing to see.

Want to know who we thought won? Mr. White of course. While he may be known for making super-addictive blue meth, Walter White's lyrical delivery is also 99 percent pure. And Rick Grimes' delivery was stiffer than a walker.

And our favorite line was this Walter White retort: "I've seen Walter Jr. handle Walkers better than you." Ouch! Grimes may need an icepack for that burn.

As a side note "The Walking Dead" returns for a fifth season on AMC in October 2014. Meanwhile, 'Breaking Bad' spinoff show 'Better Call Saul' is expected to premiere in November of 2014. Michael McKean is the latest actor to reportedly join the cast, according to Deadline.com.
