Puffy

Puffy was an Imagination-empowered toy from Mel's childhood.

Character History
When Mel, now a Train Quantum Guardian, was tapped by Hammer Shadow's hammer, a man-sized version of Puffy manifested as something precious to Mel, he would then be destroyed by Hammer Shadow in order to draw darkness from Mel's heart, as was the Shadow Creep's modus operandi. Puffy had a habit of doing the opposite of what people told him, making him notoriously disobedient.

The other Train Quantum Guardians aided Mel in protecting Puffy from Hammer Shadow. However, when Mel as Ranger 3 stood before Hammer Shadow in order to protect Puffy, he did the opposite & stood in front of Mel to protect her from Hammer Shadow's finishing blow, leading to him fading away. However, Mel did not have any darkness inside her, only light to dispel the Shadows. Using the full power of her Imagination, she was able to beat back Hammer Shadow.

Later, aboard the Rainbow Line, Mel was confident that Puffy would be waiting for her back in their old town once the Train Quantum Guardians found it.
