So one last thing to deal with, regarding Taboo-Oh: When the player does beat him, they obtain the Monochrome Costume regardless if they took damage or not. All the Taboo battles use the Ironhead system where beating the boss with no damage unlocks an item, though for some reason the Taboo-Oh fight's unlock doesn't seem to work properly
If you want, I'll send you the Taboo-Oh script.
