Mine is just based on Simba when he becomes King in TLK. Very interesting and original, I know. Maybe I should have chosen a more original and exciting username, but most people know me by this username now as I've had it since 2004, so I think I'd better stick with it.
I always pronounced your name as "Kah-say". And hey, at least it's more creative than mine. I probably deserve the award for the most unoriginal username here.
