Jump Spark is of the Scyther family. They injected it's egg with a serum made from a cocktail of different electric type Pokemon DNA and various other things. They also kept it under constant electric shock. This resulted in it hatching as a yellow Syther that was immune to electricity and was as fast as lightning. However it could not produce electricity. When it finally evolved into Scizor, the fact that it became metal allowed it to finally produce its own electricity.
Out of all the other Pokemon Team Rocket experimented with, only metal type Pokemon could actually become electric type.
Jump Spark maintains its speed and ability to fly unlike most other Scizors because it charges its metal coat with electricity making it a magnet and allowing it to push away from the Earths magnetic field.
When I tried naming this I came up with two names Jump Spark and Thunder Strike. Thunder strike plays off the Japanese name for Syther which is Strike. However I like Jump Spark because I could just imagine it putting its clamps onto a car to jump start it and frying the car with millions of volts.
