Go Planet!

Four Heavenly Kings, Gaia's champions and the main environmentalists of the KoF franchise, "Captain Planet"-inspired fanart.
This year's Earth Day may have passed, but remember - when it comes to fighting for your planet, the time is always right.

Note: This fanart portrays Hakkesshu as good guys for parody purposes, the author does not support the concept of wiping out humanity by the avatar of the eight-headed snake god.
