 * Fires 4 bursts of 3 [[File:Dread Flames (Ultranium).png]] Dread Flames at the player, which have a short delay before becoming gravity-affected.
 * Fires 3 volleys of [[File:Dread Bolt (Ultranium).gif]] Dread Bolts at the player.
 * Shoots 6 Tooth Ball (Ultranium).png Tooth Balls at the player instead of 3 and at a faster rate.
