Nyon used to be a Cybertronian Torus-City, with its Acroplex being one of Cybertron's capitals at one point.
That is, until neglect turned it into a rust heap.
There was a rather large entertainment industry centered around racing, and I was constructed cold for the purpose of being a racer.
However, it wasn't all glory. Racers were given just enough energon to keep us running on fumes.
Racers were expected to be pretty and fast, not have opinions, so when Nyon's infrastructure began to collapse, racer mechs with opinions on politics—such as myself—ended up on the street, as we were easily replaced with mechs who didn't ask questions.
I, like many others, did things I would rather not have in order to survive.
A lot of us ended up part of the insurgency, with myself as leader.
Zeta Prime labeled us terrorists.
I prefer rebels.
This was back when the Decepticons shared similar goals, though we differed in methods.
Except in one instance.
The Decepticon Swindle often supplied us with explosives, including the phase-charges for a contingency plan we hoped we'd never have to use.
Zeta Prime was draining Nyon's inhabitants of their energon, their lifeblood, to power his weapons, which left us in a hard place.
If we couldn't evacuate the city before he got to them, they would not only die, but be used against us, and other innocent civilians.
So when the evacuation failed, I detonated the phase-charges to keep them out of his hands, something I still feel awful about.
I'm doing my best to do them all proud.
