Aero Armor: I think it's good, but the times four weakness for flying types should be eliminated. (Keep the extra stab boost.) I also think versions of this for several other types should be made. Maybe Ground and Electric?
Pyro Armor: I like it. Nothing should change.
Berry Armor: this one just feels a bit... Odd. Very OP. it essentially allows you three extra recoveries.
Power Armor: I think it should just increase base attack stat by 2, instead of increasing final damage output. Also, I'd suggest replacing Strength with something else in the case of the Pokemon lacking arms/hands. Strength and Thrash are redundant. You should also make a special counterpart with maybe... Vacuum Wave?
Heavyweight Armor: Good
Reversal Armor: Good, but I'd eithe limit the uses of Counter and Mirror Coat, or increase their energy cost.
