I've done this for a lot of forums, and a lot of them turned out to be great. Now this is NOT A FANFIC THREAD but mostly just expressing ideas of what you think a season should be about or what it should do. For example, you could tell your ideas of what they should have done after "The Rebirth" or after R.I.D or any series.
Legend has it that somewhere in the galaxy, there lies a Decepticon Matrix. This matrix can only be controlled by a true decepticon leader.
After a failed assault on Cybertron, the Decepticons start reconsidering Megatron has their leader. To prove it, he wants to find this Matrix. Not only to prove that he's leader, but do gain power (like the matrix does with Octimus). The Autobots realize the Decepticons will be very powerful with these new Matrix and seek out to stop them.
But, although the matrix gives off large energy readings, it can be misread. The scanners start picking up big amounts of Energon instead of the Matrix. Although this is not bad, this throws all the Transformers off course.
The whole season is not focused on finding the Matrix (like other seasons all focus om one thing). In between trying to find the Maxtrix, Megatron trys he's evil plans to regain Cybertron from the Autobots.
Star Scream and Anti Prime (R.I.D's Scourge) find a whole fountain of energon (misread as the Matrix) and power themselves up along with the Combacticons. While the main Transformers our out trying to find the Matrix, the Combacticons, Star Scream, and Anti Prime launch on Earth. While most of the Autobots aid all this damage, the Combacticons, Star Scream, and Anti Prime surprise everyone with a sneak attack on Cybertron. As Star Scream, Anti Prime, and the Combacticons look like they're winning (because they're powerd up with so much energon) Octimus, Megatron, and the rest of the main Transformers come back from the mission and save Cybertron. Thinking they've killed Star Scream, Anti Prime, and the Combacticons, Megatron throws them into space. As they flought away in space, it looks like they're dead, but none of them have given up life yet. Their spark still spures a little, and as they hold out, they may gain new bodies from a unlikely huge planet (Unicron).
Most of the transformers have their G1, G2,or R.I.D bodies.
So how do you like it?
