Copy Cat Mem thinks it's a good idea...

[dragonofmemory]

So Nar has posted a list of characters the five things meme has spurred.  Considering mine has gone just as out of control as hers has due to some mutual trolling, it's probably a good idea to round them up. The list will be updated as new requests get filled.

So without further ado, the characters I've written head cannon for:
