The Gradeus Pearl is Pullum Purna's Meteor Combo, first introduced in Street Fighter EX 2 Plus.
Description
Executed by performing two quarter-circle forward motions and pressing all punches, Pullum uses a tambourine, making a note shaped projectile and inviting the opponent to a dance-off, if the projectile hits, Pullum starts spinning rapidly in rhythm to music alongside the opponent. She spins so fast that the opponent takes damage from dizziness and whiplash and falls down from losing their balance. She then taunts the opponent for not keeping up.
