This transformers papercraft is a SD Starscream, the treacherous Decepticon Air Commander and the deadliest of the Seekers, the paper model was designed by lilscotty. Starscream is also a big coward. The self-reported pride of the Cybertron War Academy, he's famous not only for his incredible skill, but also for his limitless (and troublesome) ambition. Starscream believes that he is more suited for command than the Decepticon leader Megatron.
Thankfully for Megatron, Starscream's mutinous, power-grabbing plots are almost always transparent, and he can never muster up enough patience to complete a grandiose power play. Even on the few times he has taken control of the Decepticons, he quickly loses control of a situation, but is too arrogant to realize when he's in over his head. He never learns from his mistakes. The only reason Megatron doesn't turn Starscream into slag is due to the fact Starscream is very good at his job of commanding the Seekers. Despite his constant failures, Starscream believes it is only a matter of time before he prevails - his destiny is inevitable.
Starscream's never-give-up attitude extends even to the afterlife: unlike most Transformers, he has a mutant, indestructible Spark. His life-force cannot be destroyed and can persist even without a body to contain it. However, there is no indication that Starscream was aware of this fact prior to his destruction.
Starscream transforms into a McDonnell Douglas F-15 Eagle and serves as the Decepticon Air Commander, leading the other Decepticon Seeker jets, many of whom share his physical design. According to his technical specifications, he can reach speeds up to Mach 2.8, and can climb up to sub-orbital altitudes of 52 miles (84 km) and nose-dive down to ground level in minutes (the real aircraft has a top speed of Mach 2.5 with an altitude ceiling of 65,000 feet (19,800 m), or 12.3 miles). His arm is mounted with launchers (mounted under his wings in jet mode), which can launch two types of weaponry - cluster bombs, each of which can level an area 10,000 square feet (900 m2), and his signature weapon, the null ray, which can disrupt the flow of electricity in any circuitry it hits for brief periods, effectively rendering any electronic device or machine temporarily inoperable.
