James Fry recently brought up some things concerning Mina The Mongoose's development on the Archie Mailing list in reference to a letter in response to Dan Drazen. An excerpt from the responsive letter is below:
Mina was always intended to be a mongoose, hence my remark wondering whether or not we made her species clear from the beginning. In point of fact, she was a mongoose before she was named Mina. The character was originally named Chloe, and changed to Mina at the 11th hour because so many of this book's female characters' names end in that "long-e" sound: Sally, Bunnie, Rosie, Amy... you get the idea. But the mongoose thing (clearly labeled on the character-design sheet Spaz sent me), the super-speed and the maybe = girlfriend thing have all been part of the plan for ages. I'm not saying stuff never gets made up on the fly, just that this certainly isn't one of them.
I wont reprint the full one. But check out the mailing list for more of the discussion. :)
