Blake Griffin is taking on Marvin the Martian in a dunk contest that will decide the fate of the Earth!

The battle takes place in a Jon Favreau-directed commercial for the Jordan Super.Fly 4 basketball shoes, and the 2011 NBA Slam Dunk Contest champion chatted with ET about what is was like going toe-to-toe with the diminutive extraterrestrial.

"It's a little daunting," Blake told ET. "Even though he's like three-feet tall and he's a little alien, he's pretty intimidating."

Fortunately for Blake, the Jordan Brand created the Super.Fly 4, giving him a leg up on the competition.

"I'm going to dunk from the foul line," Blake says in the commercial before clarifying, "the other foul line."

Bugs Bunny also makes an appearance in the ad, which gives a nod to Michael Jordan's 1996 movie Space Jam.

"I had a birthday party that was Space Jam-themed when I was a kid," Blake remembered. "On my 21st birthday somebody got me a Space Jam cake again, because they knew that happened. So yeah, you could say I was a fan of Space Jam."

The Jordan Super.Fly 4 launches Aug. 8.
