Ionix

Ionix (stylized as IONIX) is a toyline, created by Spin Master in 2013, of construction bricks that unfold and shapeshift into interesting action figures, gear and weapons, mini figures, and more, that can be placed in many shapes and positions. Its slogan is "Shapeshift. Build. Unleash!". Ionix bricks are compatible with other leading brands like LEGO. Ionix makes brick figures of known franchises like Pokémon, How to Train Your Dragon 2, and Tenkai Knights.
