Lyrics

Pokémon!
No time to question my moves
I stick to the path that I choose
Me and my friends are gonna do it right
You'll never see us run away from a fight

To be a master is my dream,
All I've got to do is believe

I believe
I've got a chance to win
I'm on my way to victory
Pokémon!
I can be a champion if I just believe
I'm on a Master Quest
Master Quest!
I want the whole world to see
I believe!
I'm gonna be the very best,
'Cause all I've got to do is believe in me.
Pokémon!
