A Chaos Tap is a Drakon device capable of absorbing excess Chaos energy and storing it within itself. Sister Haggra of the Drakon Empire provided Sonic the Hedgehog with one when Mobius was under threat of destruction by the Chaos Siphon, a Syndicate construction. The Drakons were initially reluctant to provide Sonic with a Chaos Tap until the hedgehog reminded them that destruction of Mobius would also mean destruction of the Chaos Emeralds. The Chaos Tap was then given, but Master Scholar knew full well that he could disconnect the Chaos Tap at any time, leaving Mobius at the mercy of the Drakons.
