@fetts: Hugo Danner is a power. I have let adamantium plates and carbonadium armoring, in addition to Mando iron as special items. The Hugo Danner rule does not apply to special items. I don't let people gird themselves head to toe in adamantium but the Power Suit is nowhere near adamantium anyway. It's just insulated from temperature extremes. In the case of the power suit, getting hit drains it's power. The stronger the attack, the more heavily power is drained until the suit can no longer maintain it's form and returns inside the host.
I heavily restricted @ferro_vida's energy reserves though and for the sake of this scenario, I am going to assume one 9mm bullet will take 1 point of energy away from him. An explosion will take quite a bit more. But because the suit is insulated from temperature extremes, the temperature of the flamethrower attack won't do anything. However, if it does have concussive force, as you say, then it will drain Ferro's energy.
I agree that you have MUCH more maneuverability than the flying space pirates and the homing missiles are not overly agile anyway. In fact, they are kind of sluggish with turning, if I recall correctly.
