An entry in Fortnightly Topic Challenge #35: Restricted Title 1.
A room full of me would be a child's fantasy.
Mini or large is what I can be,
I am a pirate, a superhero, and a civilian, all at once.
Make me fly or make me ride,
Allow your imagination to take play.
Foreign I may be,
But you may find my land in your own land.
You can even find me at a presidential center for show!
So, take me into your own hands to witness what I am.
