She cried uncontrollably when she got accused of secretly being Metal Robotnik/Black Eggman by Knuckles the Echidna.
She cares about Sonic, as she saved him from Hyper Metal Sonic by attacking him.
Her character design is very cute.
She does have her funny moments like when she cringes and grinds her teeth from the thought of herself married to Robotnik (pregnant and breastfeeding one of his babies), and especially the part where she kicks Hyper Metal Sonic's head for looking up her dress calling him a pervert.
At least her Japanese voice actress, Mika Kanai, does a better job of voicing her than her English voice actress, Sascha Biesi.
She's the only female character who appeared in the movie.
She may be a human/cat hybrid, as she has a cat tail.
Her first appearance in the Sonic Archie Comics was in Sonic Archie Comics #101.
In the Sonic Archie Comics, she doesn't have a tail. This may be due to an error.
