I agree with shadow's power and eagle's. Both awesome.
I would have to choose the various ninja powers and jutsu from all of the Naruto games.
Or Goku's powers from any of the DBZ games, screaming louder makes you more powerful? Sign me up!
Do you know where the real Hell is? It's inside your head.
Do you know where the real Heaven is? It's beyond the clouds, a horizon we all see in the end.
That's why my head is always in the clouds, hoping to see that Heaven beyond the horizon of Life and Hell.
Sayonara, Adios, Goodbye.
