Depends what my power would be... Although I dunno if I would want it x.x
If I did get it however, I guess I would have to use it for some good! Would be a waste otherwise. Although sadly some people may disagree with my version of good...

I could always take over the world!! Bwahahaha.

As I said though, depends what power my Geass would have. It could be an utterly useless one... That would suck.

If I were to have the power of Geass, I would use it to, first of all, get rid of all the people I hate in some way, and then just use it for every day things. No more tests, perhaps. And I would also be able to get the school to finally allow us to bring video games to class! [Some people might say noble causes, but really, do you want to use it for that? Isn't there something you want even more?]

But I don't think I really want the power of Geass, not after seeing how Lelouch had the permanent Geass. That would just scare me, and I wouldn't want something happening like Euphie's death [I liked Euphie too...]. I would probably say something sarcastic by accident and then end up killing a person.

With great power comes great resposibility, i prefer a normal peaceful life , but then again geass power may come in handy sometimes. This is tough choice, but i will choose to had geass power just for the sake of staying together with C.C.

The power of the Geass would become just another skill in my arsenal. Another tool I would use to achieve my own goals. Very much like Lelouch, but I hope to gain more control over it and understand its principles. All so that I may use it better together with anything else I might have up my sleeve.

This is kind of a very open topic, and seems that we not only choose what we would do, but also the power we were to have?

Well to shorten this span, I'll choose the power Lelouch has.
"My order is obsolete, and I can't use it twice on anyone."
Taking that into consideration, and the progress of mankind, how rapidly we are progressing towards the future, and what this future holds for this planet.
I'd have to come up with a plan, and that be;
Given I'm in the military already, that would be of help to get into presidential security, from then forth give the order to all in the way from me to the president.
By getting that far if possible, I'd have him launch all nukes, all all continents, to start a nuclear war, and impede the spread of mankind. Because in retaliation all other nations will launch their nukes.

On a more personal note, this power can be used for a while, and for personal pleasure, and gain.
So probably, this is a given, gain trustworthy allies, smart, reasonable, and build on it, until enough power is gained to go up against the democratic government of this nation, and build a new nation, and have power, after all it's what all the humans desire, and I would be a fool to say I'm different.
Then see what I can do, and what promises I can keep to the nation under me.

Ah so many ideas, so little time, and imagination can just run wild.
Geass, if I were to try, and interpret it;
G - Greatly.
E - Evolved.
A - Abilities.
S - Serving.
S - Species.

I don't want geass...but I am dreaming that a girl like C.C comes to me...hah~

This season characters with geass are more...In a sense this makes the anime more fantastic...
