The birds exploded as Sai tore through them, he moved to fast to get caught by the ice spikes, just a bit of a chill.
Aiden cursed as Chrome got involved, they fucking had him until she had showed up. Aiden, upon seeing Sai destroy his birds waited until the veritable last moment before he destroyed the ice bird he was on and just barely slipped underneath Sai's attack. Had he been a second slower, or Sai a second faster, he would probably be unconscious right now. Aiden allowed himself to fall for a bit as he charged up his next round of attacks.

"Ice Make: Dragonic Ascension" This time, instead of a bunch of birds, he just made one, and it looked a lot closer to a dragon than the other ones, as well as being slightly larger. Now that he had his air superiority back, Aiden focused his magic as he took a deep breath, the scale marks on his arms and face taking on a icy-blue glow as he released his attack. 

"Ice Dragon's Roaring Blizzard"

This was Aiden's super-powered Roar attack, a much larger wave of sub-zero cold gale-force winds filled with noticeably larger ice shards, and in a continuous stream. The attack roared at the cockly S-class mage, with the front of the attack resembling the shape of a dragon's gaping maw.
