Sharky Kraken's Eye: Sharky's ascent from trench dweller to Bloom fisherman has given him a sense of responsibility to those around him. His mother's spirituality served as a bulwark for both of them against the harsh realities of life in the trenches. Sharky did a massive disservice to his sense of responsibility in antagonizing the children of powerful shoalmongers. In turn the shoalmongers brought down their wrath on the trenchfolk. A desire to live up to his ideal of responsibility and find redemption in the eyes of his mother and their god-figure drove Sharky to free the deadliest criminals from the coral prisons. Sharky offers them redemption from a life of crime while simultaneously ridding the seas of their most murderous madmen. Sailors and seaside villages refer to Sharky as the God's Roar; his crew's brutality is such that the majority that cross blades with them scream for the gods to save them. A seed of skepticism underlies Sharky's quest, leading him to believe that perhaps it is up to him to fulfill the role of sacrificial savior, since that figure has yet to return.

It really frustrates me how slow I work, because I have so many great characters in my head, but often I only end up writing a paragraph a day, and it's usually descriptions of what I'm going to write rather than the writing itself.
But anyway, for a fic that seems a long ways off, I've created a character named Werner, a loyal friend who grows increasingly irritated with the cowardly actions of his best friend, and eventually strikes out on his own. Werner is a Grumpig (one of my favorite Pokemon ever, and Psychic types have so much potential).
I also recently came up with a character for probably my first fic. Also a Pokemon, this one from a species I created, though this character will be the only one of its species that ever appears in my work, as it's supposed to be very, very rare (due to overhunting). It's a crocodilian creature, with its species' signature trait being sadism. They are predators that play with their prey before eating them, that taunt and mock. And the character has to learn, from its irritated trainer, how to not be evil.
And last, a human character, a tough policewoman (named Jennifer) with a complex background, and a lot of guilt over past mistakes. If I get around to it, she'll be the main character of another fic, but that's a ways off.
