Looks pretty solid.  You can probably drop the Dexterity and Agility and only buy up the ranged combat and dodge from them, that might same some points.<br/><br/>Move-By Attack is an advantage that might appeal, letting you move before and after an attack.  You could swoop in, hit and swoop back out.<br/><br/>Since your sword is cheaper than your other powers, you can put some more powers in that "slot," up to 24.  Perhaps a lesser level of Change Environment: Light to have it shed a glow of its own nearby... or even the Comprehend Power.  Holding the blade lets you cut through the knot of other tongues, metaphorically.  To cut through objects more effectively, you could take Weaken Toughness, Affects Objects Only, linked to the blade's damage.  You can probably lose Penetrating, it's a holdover from when Impervious was a much stronger power.  The Darkseid analogue Omega, Power Level 19, Toughness 24, has only Impervious 18.... sort damage 12,  you could still hurt him with your blade, and even if it was 24, you could just Power Attack to overcome it.
