Since we are continuing on the subject of "If I had the dough":
Yes, I would love a monster that i can point too and say "I picked that =D", much like how Zone can say he helped animate the current Boss. Be kinda like that "pool samarai" thing that was mentioned last page from Shovel Knight.
Let's see.. if I wanted a Normal Boss critter, I'd prob pick either the Chimera like Mike said, or the Sphinx. Both are some interesting type monsters with many possibilities in design. I would of said "Bahamut" in the style of FF, but they've already hinted they want a real version XD
For a Secret Fight, I would pick either Yuri Hanna or Hyoko Dokomoshi (or both). Yuri would of been my pick if I had the funds for an Incarnation, as she's Ninja like that uses magic in the form of both vocal and hand signs (Yes, it sounds like Naruto but I swear I came up with the idea before I knew of the show/manga). If I had to put her in a Class, She'd be a dual class of Ninja/Mage, since her spells arn't Arts, but real magic that a mage would use. Hyoko's more like a Monk type char.. Goofy, ditzy, but has his heart in the right place, but with a dark internal secret.
