Dark Whirlpool

The Dark Whirlpool is a whirlpool in the ocean, which is said to be a portal to the powers of darkness. Much of its nature is not revealed, except that it was caused by the spirit of Devimon, after Angemon destroyed him. It appeared while the Digimon Emperor was searching for it to complete Kimeramon. He sent some Mekanorimon after Devimon, but they were sucked into the whirlpool, so the Digimon Emperor used a device to suck Devimon in and absorb him into Kimeramon, despite Devimon's warnings that he could not control the powers of darkness.

Any Digimon near the Dark Whirlpool would feel the presence of evil.
