Bombalurina

"Bombalurina is very sassy, very confident. She kind of has her paw in every group, she always knows what's going around, especially with the male cats."

--Caitlin De Kuyper, Bombalurina

Bombalurina is a seductive red queen. That seems to be her signature trait, and shallow as it may seem, there's not much anyone can do about it, since throughout the musical she keeps finding ways to come on to various cats. She is the first female cat to take part in the mating dance, and the opening choreography to it shows Alonzo, Quaxo, Tumblebrutus and Pouncival fighting over her, although in the end she is paired off with the Rum Tum Tugger. Like most of the other she-cats, she seems to find the Rum Tum Tugger especially attractive. Unsurprisingly, many fanfiction writers, me included, find a way to put them together...

Bombalurina also has a talent for showing up in fanfiction as a villainness. I'm not quite sure why this is, even though even I generally think of her when I'm reading about a beautiful and evil character in some fantasy book. My best guess is that this happens because she so completely holds fans, both male and female, under her spell, and it scares them. (I know it scared me!)

Probably because of her own strength and beauty, Bombalurina has a tendency to scorn the older cats, with the exception of Old Deuteronomy. She takes part in both Jennyanydots and Bustopher Jones' songs, and seems to find a way to make fun of both without directly insulting them. She also has a strong prejudice against Grizabella, maybe because she is afraid that one day she will become like the older cat.

Bombalurina has some sort of intimate history with Macavity, and seems to still be attracted to him, even though she also shows hurt and anger and fear of him.

Bombalurina's closest friend is Demeter, although she also seems to have a good relationship with Jellylorum. Bombalurina and Demeter are often assumed to be sisters, although not always. Bombalurina is very protective of the younger cat, possibly as leftover paranoia from when Macavity terrorized them.

Useful Facts About the Role

Well, obviously, you need to have a good body...no, seriously, this is  one of the roles where physical appearance and ability is pretty important. Dancing, acting and singing all play a big part in Bombalurina's role, but I would put importance roughly in the above order. She is definitely an alto part.
I think that all the most awkward interactions are covered by the Rum Tum Tugger, although in some productions Pouncival joins in. I really hate to say this...but it's pretty obvious...if you want to play Bombalurina, you'll need to be okay with being touched.
