The ideal Calliope can show a slight (but strong!) contrast between Calliope's ideal self, her cutie-patootie trollsona, and her true self as a cherub. She is sweet and passionate and just a tad shy at times.

NOTE: May also play Alternate Calliope, who I envision as having an ancient, wiser voice, deep and mature. She has embraced her nature as a cherub, a stark and disturbing difference from the Callie we know and love, and gets to have her own villainous lilt once we hit post-canon. 

HC: British accents required, however, the more fun you can have with the accent, the better! I love the thought of it sounding ridulously posh and fake as hell, but she really does just talk like that. I imagine her trollsona voice is a bit of a lighter bubblier pitch, while her true voice is raspy, lower, unconventional in its femininity, and maybe with a tiny bit of a growl. She's a monster girl and we love to see it. Trans VAs encouraged, because it'd be a delight to make her struggle to accept herself into a gender identity metaphor on top of everything else.
