Armsmasters only has a handfull of option.Okay, I'll bite. How exactly do you expect him to escalate? Try to tackle the Dragon that just melted his halberd? Try to shoot the thing that can breathe melting point fire? Remote control his motorcycle to crash through the wall and try to kamikaze the living flamethrower/plasma torch/hydrogen bomb? Run away screaming for backup?
Admittedly, the last one would make a certain amount of sense, but his uniform is blue, not brown so....
- Intimitade Taylor: Look undisturbed and demand her to yield. Ideally while listing all the felocities she might have done.
- Attack Taylor: Even with his main weapon gone he could have X other minor gadgets on him that could be something as mudane as pepper spray to range as far as tinkertech gadgets. In canon he got his weapon teleportet back to him after the raid on the celebration. It stand to reason that he might 'magic' up just that and get a replacement weapon teleportet to him.
And even without he is a very skilled hand to hand fighter in POWERARMOR that allow him to throw it down with low to mid tier brutes.
- Disengage Combat: Tactical sound to retreat and get out of the range of an unknown parahuman.
- Call Support: He knows of 2 or 3 members of New Wave beeing there at the moment. That is a lot of firepower even if not under his comand.
Most likely a combination of the above. Like getting a bit more room to evade possible attacks while staying colse enough to attack while pinging HQ to sent reinforcments while telling Taylor to surrender while activating tinker bullshit to get a replacement weapon.
I see it as out of character for him to call New Wave for help because of his pride and more likely to 'ask' them to stay out of it and in the worst case ignoring what they are saying to defuse the situation.
