I don't have a name or back story for this guy. It was partly inspired by Transformers: Energon Arcee.
I'm not 100% sure I like the robot form, could use some work.
It does transform but in order to minimise the bike kibble in robot mode I've turned the front stabiliser into a detachable cannon.
Motto: Finding your target is easy, loosing it is hard.
Background: Blacksun was personally recruited by Shockwave to the ranks of the Decepticons. Recognised as the type of homicidal psychopath who enjoys killing, Shockwave made it his mission to groom his new toy as a killing machine, as emotionless as himself. Unfortunately for Shockwave his efforts failed. While being amongst the most talented assassins the Decepticons have ever trained, he takes far too much pride in his work for Shockwave's liking. Success is so important that failure can cripple Blacksun, leaving him morose, withdrawn and reluctant to take on new missions.
Skills: As a swoopbike Blacksun is equipped for tracking prey at ground level, which he shadows at a distance until they are alone and exposed. In robot mode he uses an electron stream rifle, capable of ionising armour for a distance of 1km. Accuracy is 99.9%.
Weakness: Flight capable target can evade him easily due to his low altitude flight and slow speeds and reactions. His weapon is useless against ion shields. His major flaw his his personality which treats even the slightest failing as critical.
