DEATH BATTLE!

DEATH BATTLE! is an ongoing Rooster Teeth webseries where two fictional characters fight to the death. The series is at 125+ episodes and is still ongoing.

The series has also been adapted into RP, being hosted by Jet Set Radio.

Chiaki Sakura Rose talks about them on her alt, CSR Productions.

Overview
DEATH BATTLE! began in 2010 with a basic concept, analyze two fictional characters, have them fight, and see who wins. The first two seasons went on without a relative schedule for a few years, but come 2016 with an expansion of staff, each Season starting with 3 lasted a year each.

The episodes feature traditional research using scientifics and online encyclopedias while the fight section of the battle features sprite, 3D, or hand-drawn animation, perhaps even Live Action. Of course, the battles always end in death, or some form of death.

A spin-off with no research debuted in 2016, known as DBX. The winners were decided by the animators, but in Season 4, the show was revamped to be weekly and the winner was viewer decided.

RP Adaptation
While the actual show has been stated to exist AND end in death, DJ Professor K and King Dedede run their own version of the show on Jet Set Radio, with research handled by Weiss.

Despite this, it seems that Weiss always seems to vanish from the studio during battles and something goes wrong, leading to match-ups never finishing.

A current list of the episodes is featured here.
