I would like to see a new variation of power armour that boosts Agility (and possibly Perception), like the current power armour does for Strength. From the power armour frame to the six armour sections (helmet, torso, etc.) should emphasize the change in focus, such as increased range of mobility to avoid damage vs. the original's capability to withstand heavy damage.

Examples of increased mobility would be flight (as opposed to power jumps) with a flight pack (v. a simple jetpack), and having the ability to swim in the armour, instead of just plodding along the bottom of the lake, for example. Unique mods for the armour sections could include a sonar suite (to allow the PA pilot to 'see' underwater) that could potentially be used as a sonic weapon while out of water, retractable sword blades (that could be enhanced with energy, such as electricity) - great for giving it a kind of anime feel to it), hydrojets for increased swim propulsion, etc.

So what you're asking for Is basically the Iron Man suit.
