I want to know all the pokemon you can remember travelling across a region with.

Doesn't matter if it was a nuzlocke.
Doesn't matter if you were 8 at the time.
Doesn't matter if you only used it for a singly gym.
If you can remeber playing through a maingame with it, highlight it.

Don't go booting up saves to check, it's what you can remember that counts.
Only travelling through the maingame counts, nothing you used purely postgame.
Gen II's Kanto doesn't count as postgame for this
I kept tripping on this, by forgetting certain things were used for facilities or I've only ever used competitively.

Don't forget to r8&h8, or share stories.
