Anywho, this is just me brainstorming ideas for the plot.
A Titan is the source of the hotspot and is awakened by the arrival of the Decepticons?
Titan doubled as prison ship?
Both side attempt to bolster their ranks by using the hotspot?
Atempts to weaponize Energon?
Attempts to construct a space bridge?
Vehicons, as shown in Beast Wars uprising?
member of the 13 shows up?
Temporary alliance to combat a greater evil?
Planet is Alive?
Planet is an artificial construct, but what purpose does it serve?
Transformers who are heads to heads?
Transformers who are engines?
and lastly, Allspark discovered, Allspark shattered. Battle over the shards. Each shard does something different.
Oh. and Quintessons. that would be fun.
