Transformers: Arcee

Transformers: Arcee is a Transformers fanfiction by Sean Bridges.

Plot
Princess Arcee, one of the Princesses of Cybertron, has been sent to Earth because of an invasion of Predacons from the planet Destron. Once she arrives, she has to create a human disguise in order to blend in with the humans.

Princesses of Cybertron
There are three kingdoms on Cybertron, each of them with a king ruling over them. The following characters are their daughters, who are to live in exile until the Maximal-Predacon war is over.
 * Arcee: The lead character in this fanfiction. She is unaware of the war on her homeworld, or that humans aren't exactly the friendliest organic beings in the galaxy, until she finds out for herself from Airazor. Her alternate mode is a jaguar.
 * Airazor: The second Princess of Cybertron to appear in this fanfiction. She is about a megabyte more mature than Arcee is, and keeps cautious around humans, even the ones Arcee has made friends with. Her alternate mode is falcon.
 * Whirlpool: The third Princess of Cybertron to appear. Her personality seems to be based on the Fuzor Silverbolt. Her alternate mode is a dolphin.

Other good characters

 * Cosmos: A "Saucer-bot" that Arcee keeps as a pet. He speaks fluent Mini-Con, but not Cybertronian or English.
 * Nova: A character that masquerades as a Princess of Cybertron, but is not. Near the end of the story, it is revealed she is Unicron's daughter. Her alternate mode is a rabbit, but she is stripped of her Transformer powers when her father swallows her up.
