Leo builds his dream creature and immediately learns that invention doesn't mean control, Aquro has his own will, his own fears, his own reasons for what he does. That gap between creator and creation is where this show lives, and it's sharper than a mon-collection show has any right to be. The Elemon Blender isn't a machine that makes collectibles; it's a door to something real, and every new creature that walks through it reminds you that Leo doesn't actually know what he's made.

Leo is a young genius inventor, and one of his creations is Aquro, a water-type Elemon. Elemon are mysterious creatures that come out of a device called the Elemon Blender, and each one carries the power of an element. Leo and Aquro set out together to explore a whole universe full of different Elemon, and the friendship between the two sits at the center of the story. The result is a sci-fi action adventure series built around science, discovery and the bond between an inventor and the creature he made.
