First off: NO SPOILERS PLEASE.
Okay, I plan on completing EVERY Trophy in this game, as I try to "Complete" any and all 3DS games I have. That means, unlocking all unlockables which also means: Secret Ending. Now, I was planning on going "Proud Mode", yet the last KH game I played (BBS) was a literal bitch to beat with Terra. That second to last boss battle very nearly made me murder something.
My question is: Is there a boss as tough as Master Eraqus or as unfair as Master Eraqus in this game? If so I may just go for Normal Mode.
