Crimson Planet is a 2.0/2.1 Extreme Demon mega-collaboration hosted and published by TrueOmega and verified by Wooshi on May 19, 2018. It is extremely difficult, despite being very short for an Extreme Demon, (almost three times shorter than Bloodlust), Crimson Planet is considered to be harder than Bloodlust, but Zodiac is considered harder, as it is over two minutes longer than Crimson Planet. When Zodiac was moved to the Legacy List due to an update, Crimson Planet became the #1 Demon for one day before Zodiac was reverted.
