Actually, I think I'll go into more detail about why I choose wind. I assume we're going by anime rules. In which case, not only can I use my powers to create tornadoes and powerful winds, but also vacuums, I can fly, and even cut things. Give me a knife and I'll throw it through solid stone.
Case by case fights.
Vs Fire
Probably the easiest element for wind to defeat. Try to create a powerful attack, and I'll disrupt it with a basic wind attack. Throw a fire ball at me, and I'll send it back to you. Even if you're immune to fire, you still can't see or breath in the smoke. So while you suffocate in the smoke from you own attacks, I'll just create a safe haven where it can't get me. Bottom line is this is a flamethrower going up against a tornado. Which do you think will win?
Vs Water
More dangerous than fire perhaps, but largely depends on how the water powers work. If you need a source of water, I could easily get you away from any such source and defeat you. Virtually any water attack could be overcome by enough wind. Tornadoes aren't just destructive I could use them to prevent any of your water from reaching me. On top of that, I could cut through water with sheer force being applied to it.
Vs Ice
Ice attacks would be much more threatening with their more solid force. Unlike water and fire, which would get easily carried away in the wind, Ice would need a more direct force. Still, wind would eat through any shield of ice, and ice attacks would erode against a powerful wind counter.
Vs Ground
Ground attacks would be more difficult to counter. Unlike the others, earth would not freely flow with my wind, or dissipate in a strong wind. I'd have to resort to using my wind powers to dodge and avoid the attacks rather than directly attacking them to overcome (Note: against the other powers I'd have that option, too, just more necessary here). There would also be the issue of overcoming earthen defenses. A strong barrier of earth would be very difficult to break down. On the other hand, it would also prevent them from seeing my attacks. Like I said, give me a knife or something, and I'll cut through solid stone.
Vs Electricity
Probably the most difficult to beat. Electrical attacks would be near impossible to counter of dissipate. Someone suggested earlier creating a vacuum to prevent the attacks from reaching me, but that seems like a bad option as it would reduce my maneuverability, one of the biggest strengths of wind powers. Assuming the power of flight, that would protect as long as electricity requires grounding, but would also leave me open to attacks, too, some of which might not need grounding. Keep in mind electricity would not have many options to defend against my own attacks, either. In the end, it would be a battle of attrition. Who would wear the other down first?
Wind powers all the way. Great offense and defense!
