Megatron is actively hostile when fronting, often ranting and spewing profanities. He's not unreasonable, but he doesn't like people and he hates the current world's events. He will make sure you know just how much he hates them, and just what he thinks of it all, and it's not really a productive conversation.
Reactionary behaviors aside, Megatron exists to protect the body from aggressors. He's smart but mean, and not at all afraid to fight dirty. He fronts when the body is actively in physical danger, and sometimes when the body becomes to frustrated to function.
Scary as he sounds, it is possible to talk casually to Megatron. He's hateful but not malicious towards individuals, and isn't going to risk upsetting the rest of the collective by acting out of hand. He's just old, angry, and in no small part, scared. The world is scary and dark and horrible and Megatron is brutally aware of it. He doesn't feel safe, no matter the situation.
Sometimes a facet forms from something dark and frightening, but Megatron shouldn't be demonized. He's as much a person as any of the other facets in our system.
"It's ignorant to think anything has changed from decades ago to now. Progression has been halted time and again by those in power, those who should have that power stripped from them like hide from game. I tire of it. I tire of watching the same stories on the news over and over and over again. I have no interest in debate, only change. Nothing has changed since the writing of Towards Peace."
Of course, I'm aware that this body did no such thing. This body is not to unlike those I once stood for. What irony that I be placed here after so many eons of power. Yet, given the opporitunity, I would do it all over again.
Perhaps I would try to avoid the same level of violence."
