Sonic: Nazo Unleashed 2 (Working Title)

Part 1: Mugo the Disaster
The first part of the movie is actually a flashback to the Events of Nazo Unleashed, taking place around the Same Time as Nazo's clash with Team Sonic. Lieutenant Griffith is seen exploring the downed Angel Island, were he discovers a secret temple hidden underneath the Emerald Shrine. Upon discovering a log of books that discuss the Seven Chaos Monsters, he is given an alert from his C.O. of a similar creature to Nazo attacking Station Square.

In Station Square's city hall (The same area as seen at the end of Speed Highway: At Dawn), Rouge and Omega arrive alongside G.U.N. forces to notice an unknown creature causing destruction. While the G.U.N. soldiers attempt to speak to the monster, it simply ignores them and attacks anyone that gets close to it. Rouge then takes the lead and tries to talk to the monster herself, however she is met with a similar result, with the only thing the monster says is "Where are the Chaos Emeralds?!" With conversation becoming pointless, Omega and Rouge attack the monster with everything they have, and at first, their efforts appear to be in vain.

Meanwhile, Lt. Griffith is on board a Harrier Jet, and notices the battle between Nazo and Shadic on Angel Island. Rouge and Omega also notice the battle too, as they take this opportunity to subdue the monster while it seems to be distracted by Nazo's Death Ball. They are ultimately successful, as the monster seems to "Shut down" after being captured in a Reinforced portable prison.

After Rouge and Omega meet up with Shadow, they all share with each other what happened during their respective battles, as Shadow expresses his anger that they only captured the monster, but didn't destroy it. The part ends with Lt. Griffith walking into the Monster's holding chamber and smirking at it.
