In what order should I verse the Birth by sleep optional bosses

From Easiest to Hardest?

Also, How do I unlock the battle to defeat No heart and Eraqus's Armor? 

You need to level up the arena.

What arena level?

What arena level?

Eraqus is 28

No Heart is 30

 

 Yeah it's a bit of Arena Grinding.

From easiest to hardest, in my opinion of course:

 

Monstro (if you count it as a secret boss), Vanitas Remnant, Master Eraqus' Armor, Mysterious Figure and Master Xehanort's Armor.

I completely agree with this order. MF is hard, but No Heart is harder.

I believe you mean Young Xehanort.

Yeah Young Xehanort

I believe you mean Young Xehanort.

 

Yes, yes. I know that.

Doesn't change the fact that I think he is a very overrated boss. He's tough, but not anywhere close to as bad as people make him out to be.
