Mission 69: Vanquish the Heartless threat
An unidentified giant Heartless has surfaced in Wonderland. Find it and eliminated it at once.
Roxas must defeat the two giant Heartless known as the Crimson Pranksters in Wonderland.
Proceed to the Bizarre Room to encounter the targets.
As there are not one, but two Crimson Pranksters, this mission will be even more difficult. The main thing is to keep track of both Heartless and watch their attacks. As your HP drains when on the ground, this will largely be an aerial battle. Glide is a necessity as you can stay in the air for a longer period of time, losing less health, along with Cura so Roxa's HP can regenerate while it is in effect. Also keep their HP as close as possible so when both of theirs are low you can quickly and carefully take them out in quick succession to prevent the other one from being revived.
This mission can be a nuisance due to the fact that the Crimson Pranksters can revive each other if not taken out in quick succession. Thus, you'll have to alternate between them. Stay in the air as much as possible, use your Limit Break when you can, and bring Aero Magic, as it is most effective against them. Thundaga can also help. Auto-Life and Limit Recharge panels are recommended. If it is still too tough, come back later when Roxas is at a higher level and has a better Keyblade that specializes in raising the attack stat but without any bad aerial combos.
