Dread Joker

Joker is another member of Dealers. He is able to Wave Change to Grave Joker, a powerful EM being who fights with brute strength. Interestingly enough, he does not have an EM partner, and seems to draw upon Meteor G itself, using the "Finalize" transformation (similar to Finalized Noise in transforming to Black Ace or Red Joker) when Wave Changing.

Grave Joker is the second-to-last boss fought in the game's storyline (disregarding all v2 bosses fought in the Meteor Server). He is capable of the following attacks:
 * He slams the ground, causing three blocks to appear at random panels. One of these blocks will appear on the player's current position.
 * He moves up to the player's position and swings his knuckles at the player twice.
 * Meteor G Laser - Grave Joker charges up some energy before firing off a huge laser that will crack panels. This attack must be dodged.
 * Destroy Missile - Grave Joker constantly fires off a stream of missiles at the player.
