Hello there!

I have a potential plot in the Sonic movie universe where Sonic's biological father, arrives on Earth, seeking out his son that he was forced to leave when Sonic's birth village was attacked. However, he is captured by G.U.N and taken to a lab where aliens are being researched. 

Long story short, Sonic eventually finds out that his biological father is in  lab, being experimented on daily. Chaos and adventure come around as Sonic, Knuckles and Tails seek out Julian "Jules" the Hedgehog.

I don't have an roleplay document written for it yet, but you get the basic idea.
