I've done everything there possibly is to do on BBS and have beaten every other Kingdom Hearts boss

But I can safely say for me Mysterious Figure is the strongest boss.I've tried everything maxed out hp, Renewal Barrier but have had no hope :angry: anyone have any tips so I can beat the only boss I haven't taken out

Cheap tactic? Spam thunder/fire surges

I defeated him by equiping four Thunder Surges and four Curagas.

Spam Thunder Surges and heal when you can.

Cheap tactic? Spam thunder/fire surges

 

Fire surge is not a good way to go- thunder surge all the way

As everyone said, use four or five thunder surge and the rest curaga. The only problem is defeating him with Terra. He's harder with Terra.

I can't even beat the lingering sprit

Spam thunder surges and ALWAYS roll. Just keep rolling and dodging.

Thunder surge us slightly quicker than fire surge so use that.

like everyone said thunder surge and curaga. Also make sure you have ma out Attack haste and Magic Haste. Also Second Chance and Once More. After that it is down to luck

Thunder Surge

Thunder surges and Curaga. Avoit at possible his chain attack and last ... luck ... so damn good luck hehehehehe

Thunder Surge/Curaga I can't see another way to beat him and true he is a pain...
