Dread Gravity, known as Dead Gravity (デッドグラヴィティ, Deddo Guraviti) in Japan, is a Special Move used by Hyde with his Hades H3 11Turn Zephyr' as well as Count Nightfell with his Left Eclipse 11Turn Zephyr'.
Whilst in Defense Mode, Hades circles around the opponent, Hades or Eclipse slowly closes in while knocking them around. For Hades, a purple stream covers Hades as it closes in on its opponent, knocking them upwards in a pillar of purple light.
For Eclipse, the move is performed in the same manner as Hades, but in a yellow light. Due to the Eclipse Layer being lighter than Hades, it is not as powerful as Hades' version of the move.
