Derpy, with her flying into the Sky Armour with idiotic speeds, utterly turned the SA into scrap, wich promptly began falling into the sea below. The sonic boom that was released knocked two more SA's into eachother, putting them out of comission too.
EMily destroyed four SA's with her lightning bolts, making most of them blow up in the process.
Sara's Fission Beam easily pierced through the Spitfire's flimsy armour and destroyed them.
The singularities from Gwen destroyed four more SA's.
Winona's Z0 bombs knocked several SA's off-course, making them crash into eachother. Six more SA's and one Spitfire met their end this way.
Reimu's energy needles pierced through and destroyed four more SA's
A Spitfire fired its Absolte Zero cannon in the general firection of Austin. All that was hit by the cannon fire would instantly be frozen solid.
Two SA's fired their Tek Lasers at Four. Another SA launched more Tek Missiles at Winter.
Group 1, go.
55 Sky Armours left. 14 Spit Fires.
