You didn't know Batman started a heavy metal band? You're missing out. 

I could of sworn I put these guys first video up on the Buzz website before. Now I can't find it, oh well. I will put their first video above and the new one below. The Batmetal band includes, Batman of course, Robin, Nightwing and Red Hood. The first video just had some basic Batman references.

The new one actually has a plot. Batman is saving Aquaman from evil sea creatures. Well I didn't think Ariel and Spongebob were evil, until this video. The song is pretty hilarious if you read the lyrics. I think the animation these guys do is amazing. Seriously, someone at Cartoon Network, hire these guys immediately.
