Pretend you are Knuckles...

[Mephiles]

Bit of an effort don't you think XD besides rouge would just find them again

[Claude_X]

Make someone else Guardian it.

[Proto_Blaze]

id sleep on it. then have kids, give one of them the emerald, and sneak out one night and never return

[Shonic]

[Snooky]

The entire world...
Within my grasp...
Everyone...
Under my control...

[sonicfrenzy]

[werehogsupersonic]

i would keep it because it is shiny.

[Enith]

So your asking me if I wanted to keep an emerald that contained unlimited power or get rid of it....I think we all know the smart choice here.

[Shadow84786]

I'll keep it for crying out loud and guard it so nobody won't steal including Rouge the bat

[SonicFan47]

I would keep it for the same reason he does
I'm the last of my kind with a sacred duty.
Yeah, it's a boring life, but that's why I'd buy a computer with internet service.
And I get to kill anyone who tries to steal it 

[flick]

keep it so i could do anything
