So these are the clues i took from Mins intercepted messages 1-4 to give us a clue about the new hero.
We know that there is an unknown faction of a sort of “kill squad” who has some heavy weaponry. We know they made a crater in their fight, so it could be something like a bomb or something else. Could be multiple characters or could be like hivemind, just different little bots that carry heavy power (again just a thought, could be multiple people in the faction
A single person is hitting multiple locations. So to me, this sounds like a hired mercinary. Someone who will get the job done, as long as they get payed. Mercs usually dont care who is on the other side of the gun. they hit hard, complete the task and get payed and they are gone.
So with the traces of Heronium found in the crater, we can say this mystery guy will have a warhead of some sort as an attack. but it being a strong attack, maybe its a last resort kind of thing.
lastly, this is a very dangerous character. like one of those raid bosses you fight in game that can kick your ass because you are so underpowered.
So my take is that this is some sort of raid boss. Can it be a strong little hero? sure.
What are your takes on the messages. remember, the reveal happens tomorrow. So keep your eyes out.
