In revisiting and reworking the Loose Canon manuscript, I realized Serenade doesn’t seem present enough in Season 1, considering she’s supposed to be the main antagonist. She’s clearly present in episode 05, there’s a brief glimpse of her in episode 06–then she disappears until episode 11, when she launches her Rat King attack on Earth. I want to try to add her to some of the interim episodes, and one possibility is the Fable episode, where Spark becomes a ferret and Vahaadi becomes a caracal.
Serenade’s design is modeled after a mouse, but if she were to appear as an enemy in that form, she wouldn’t be very threatening! As a ferret, Spark would be bigger than she is, and Vahaadi could eat her in one gulp! (NOT that I think it would even occur to him to try, I’m just saying…)
Her hennin is supposed to resemble ears, but in looking at it, it also resembles a cobra’s hood. Plus, she’s got that diamond motif going on…so, what about a cobra?

It’s kind of a departure from my plan for her, but I think it will be a lot more exciting to see Spark fight with a cobra! While the mouse motif better suits the Pied Piper vibe, a cobra kinda elicits a snake charmer vibe, which is also cool. And I get to exploit her diamond patterns! What do you think?
