I agree. Iron Fist's character resides on three pillars, a TRIPOD TRIFECTA if you will, of 1) multibillionaire-ness, 2) incredibly zen dude from otherworldy hidden asian city, and 3) social goofiness.
Of course, when they were partnered, Cage and Fist could switch off. I remember when Luke visited K'un L'un and everyone spoke in zen haiku mysticism, but whenever Luke spoke jive-lingo, everyone complained, "You speak in riddles!"
