Transformers: Bloodline is a fan-made story by me focusing on Starscream and his daughter Rubywing, but features as well a cast of other canon characters and fan characters.
Name: Anklebiter (Fan character)
Alt mode: Smart Car
Anklebiter is a very small Transformer who compensates her short size with an efficient scheming mind.
While she is particularly caring towards her allies and loyal friend, in battle she will take every measure to make sure her enemies are extinguished in the name of the greater good.
