Thunder Jackson has reached level 40. Here's screenshots of all the Wind powers, except the energy builder. All are at Rank 3 when pictured.
This is Hurricane. Seems really devastating, as it has extremely high close maintain AoE damage, and it costs little. It's probably the most lag-inducing power in the game, as it has a shitload of particle FX. Repels, final pulse has Knockback on nearby foes.
Here's the same with a colour hue demonstration.
Whirlwind. It's in the Snowstorm family, being pretty crap for dealing damage, but the attack Snares all enemies in it. Pretty shit IMO.
This is Updraft. It's the first Charged ranged knock-up attack. Best part of it is that it can remove travel powers and deal good damage.
Djinn Air Elemental, controllable pet. These are the three looks it can have at Rank 3.
This is Gust, the Tier 0 power for Wind. It's probably the best Tier 0, as it has decent damage, it's cheap and it charges REALLY fast. Also, looks like a Hadouken, repels enemies, and knocks down Disoriented enemies.
This is the aura for Stormbringer, the passive for Wind. It's probably the most awesome Offensive Passive, as it covers three types of damage (Crushing, Ice and Electricity).
This is Twister. It's a standard charged Paralyze power, and has no extra goodies.
Those small tornados are Dust Devil powers, which are small "summons" that deal damage nearby and Disorient.
Wind Breath, looks absolutely fantastic. Standard damage, but splits damage between Crushing and Cold. Can cancel travel powers with an advantage and cause Knockdown with another.
And finally, Typhoon. This is a wicked cool looking power, and a great line AoE that's main weakness is Damage Reduction powers due to splitting its damage between Crushing and Ice.
