It depends on whose side you're on. On one side Light is the antagonist because he is killing people. On the other side L is the antagonist because he's trying to stop the main character Light from making the world. It really depend on how you see the situation, and who you see is "justice." There's also discussion of Ryuk being the antagonist since he brought the Death Note to Earth and started everything.

Death Note: Another Note: The Los Angelas BB Murder Cases is not something that you can watch. It is a spin-off novel from the original Death Note series by nisosin.
Beyond Birthday (aka BB) is a maniacal killer who is not in the original Death Note. He is introduced in Death Note: Another Note, the Los Angeles BB Murder Cases (a prequel to Death Note) as the head antagonist. His true appearance is unknown, as he cosplays as L. His personality is quite the opposite of L's, however; BB's goal is to become the world's best criminal or, more specifically, to devise a plan that L cannot solve. BB was born half-shinigami. He did not have to make the 'eye deal', unlike Misa Amane and Soichoro Yagami of the Death Note series. Like Wammy children, who seem to have certain quirks, BB's quirk is his love for jam. I'm guessing it adds to the 'blood-like' creepiness?

In "The Masque of the Red Death" by Edgar Allan Poe, the antagonist is the Red Death itself, a deadly plague that ravages the country. The Red Death symbolizes the inevitability of death and the futility of trying to escape it. The rich and powerful Prince Prospero, who tries to avoid the Red Death by locking himself and his followers in his palace, also serves as a symbolic antagonist in his defiance of mortality.
