Death Battle is a Youtube series which has one case study to put two or more characters ,usually from comics, films, video-games, anime and TV series and put them fight each other gladiator style to the death. And it rocks!
The hosts Wiz (Ben Stiller) and Boomstick (Chad James) really put themselves in to the project and they and the rest of team do their best to find almost anything about the characters in each fight and how that skill or weapon would effects the match. This in depth look ,made me love the show for it takes the silly idea of primary school and examines it in a analytical yet hilarious manner.
And thanks to this series you get to know series, video-games or films that had passed under your radar and then after watching the fight you can go and find out and enjoy it yourself. That is how I learned about Spawn the series, Gamera, Gundams and many more.
Also as for the style sometimes it in pixel form, others 3D, either way is addictive and definitely worth watching even if you disagree with the final result.
All in all is on Youtube ,it worth your time and definitely go watch them all!
