So this isn't something I talk about a lot, but I happen to be into Beyblades, and have been since the days of Beyblade's Metal Fight. I always found them to be kinda cool. But one other thing I enjoy that uses tops like this is Pokemon Ranger. The stylers in those games use small tops to run around and draw loops around Pokemon to capture them.
What I made here are tops that sort of combine those two ideas. They can be used to temporarily capture many creatures (aside from humans and dragons), but also be used to attack enemies like in Beyblade Metal Fight. They can also be charged with different elemental powers and use them for varying effects. For example, the Ice one would be able to freeze the ground it runs over, and the Fire one would be able to surround itself with flames to attack.
Additionally, while the tops in Pokemon Ranger need to be directed with a styler, these tops can move independently like in Beyblade.
Each top is about 3 inches in both height and width.

This isn't meant to be anything canon to my Dragon Rider world, I just think it's a neat idea.
