Whenever you defeat a boss (Either in the normal game or during Boss Rush) you can go for a Pose Bonus using Juste or Maxim. These bonuses don't actually do anything, they're simply there to see how well you can time a pose.
To get a Pose Bonus, grab the orb that appears after killing a boss while in the last frame of Juste or Maxim's attack (IE, when Juste's whip is fully extended, or Maxim's sword is completely out). If done successfully, you'll see a Pose Bonus message like 'GREAT!' appear over your character.
The higher in the air you are when you do this, the better your Pose Bonus.
