Quickly choosing a fire/mental blaster, neither of which I had played much, I tried "Glass Cannon" as his name. It, not surprisingly, was taken. Ok, I thought, if not glass then porcelain. A quick check of the spelling serendipitously showed me there was a dog breed named porcelaine (with a final 'e'). I was tempted to name him, "Porcelain Porcelaine", but quickly rejected it. ("Monstrous Monstress" is funny; "Porcelain Porcelaine" is just .. obtuse.) Even "Porcelain Cannon" was now out.
His unwritten backstory would have involved a wizard's young child messing with magic. He unwittingly changed a figurine of his mother's into a living being, full size and still made of porcelaine. Though starting out a villain, he would have eventually changed his alignment to rogue.
In the picture below, I forgot to shut off the darn VG emblem of a lightning bolt. It detracts from the figurine look I was going for. BTW, I know porcelaines have big floppy ears. Alas, ears such as those were not available.
