OK!

OK! is the third Japanese opening theme of the original series. It was also used as the opening theme of Emperor of the Crystal Tower: Lord of the Unknown Tower in a version called OK! 2000. It was used as well in Mewtwo! I am here!: Mewtwo Lives.
It debuted in EP117 and was replaced by the Whiteberry Version of Aim to Be a Pokémon Master in EP192. It has been noted that the OP visuals were used with very little change or rearranging for the third theme song for the English dub, Pokémon Johto.

OK! Let's move on
OK! If we're together, we'll be all right
OK! Even if the winds change
OK! Our dream won't!
We've been so focused on getting here
We hadn't even noticed
The key to the door to a new world
Had been obtained before we knew it
Golden sun & silver moon
The lady sun and the lord moon
Take turns showing their faces
And protect everyone
And, then, so...
OK! Let's swallow our fear!
OK! With my prized move, "Bravado"
OK! Though I don't know their names or voices
They are waiting for me!
I want to meet them!
OK!!</ab>

The key to the door to a new world

Golden smile & silver tears
Delight and frustration
Take turns showing their faces
And give strength to everyone
OK! Follow me!
OK! Our spirit can't be beaten!
OK! Even if we hit a wall
OK! This journey won't end!
There are times when I had begun to give up
It's not like it's never happened
But then my fired-up self from the first morning of my journey
Asks me if I'm willing to let things stand
Golden sun & silver moon
The lady sun and the lord moon
Take turns showing their faces
And protect everyone
And, then, so...
OK! Let's swallow our fear!
OK! With my prized move, "Bravado"
OK! Though I don't know their names or voices
They are waiting for me!
I want to meet them!
Let's go!
OK! Let's open the next door!
OK! With my prized move, "Recklessness"
OK! We cried and laughed together
My comrades are with me!
I believe in them!
OK!!</ab>

==Trivia==
* A longer, creditless, 3:29 version featuring the full OK! song exists. The original opening animation is supplemented by clips from the Johto TV series.
* The sentences before the chorus make reference to the Pokémon Gold and Silver games, although the word "gold" is rendered as "golden".
* Although this song is for the first Johto/Generation II anime season, the lyrics make a reference to a "prideful move" named からげんき Karagenki. This was introduced as an actual move in Generation III (translated as ). It is unknown whether this was a simple coincidence or not. However, the song also mentions a move called むこうみず Mukōmizu which isn't a real move. So, it could be assumed that the song is merely saying to do an action as if it was a move.
* This was the first opening theme to fully feature digitally colored animation. (A portion of The Rivals was also digitally colored.) The actual episodes wouldn't follow suit for another 144 episodes, in Here's Lookin' at You, Elekid.
