And then there's the Ruby Princess in Shisui, who is Roegadyn-sized (okay you can make up an explanation for this one as being related to the voidsent possession or something).
For even bigger parties, they make even bigger enemies. The enemy dev team simply see this as a necessity for multiplayer battle content, I guess.
