Fire Manipulation

Water Manipulation

Air Manipulation

Earth Manipulation

Electricity Manipulation

Ice Manipulation

I remember one time in my childhood where i was just unplugging and plugging an outlet, and suddenly electricity just sorta sparked out. that scared the shit out of me as a kid and sometimes i wonder if i would've died there lol

Frozen to death seems like the least painful.

I disagree.. i think it'd be the most drawn out, and thus, will hurt more.

Electrocuted (electric chair) is probably the fastest way to go out,

Ay, ice will numb your body so you wont feel a thing.

Water manipulation includes Ice manipulation. I prefer Electricity... but honestly, living in a country that is fricking hot 80% of the year is telling me to go with Water or Air.
