Tatsu Steed can be seen as a Nightmare Dream Eater or a Spirit Dream Eater. In both forms, the Tatsu Steed closely resembles a Seahorse with very big fins. It has a spiky tail, and it's Spirit/Nightmare logo is on on it's torso just under its neck. It also has two spikes on its head and two ear-like fins on its head.
 Spirit Dream Eater
In its Spirit Dream Eater Form, the Tatsu Steed's body, other than its torso, is a deep blue color, and has pink/beige areas near the edges. On its tail, there are purple spikes, and the spikes on its head are purple and fade to yellow at the top. It's torso is green on the bottom, and fades up to yellow. It also has small purple spikes on it's torso.
 Nightmare Dream Eater
In it's Nightmare Dream Eater Form, the Tatsu Steed has a much darker color scheme. Instead of a deep blue color it had in spirit form, it now has a navy blue color for its body, and the edges of its fins are now a darker pink and yellow. Also, the spikes on its head, tail, and torso are an aqua color, and they fade into purple on the top. It's torso is purple for the most part, and it turns red the closer it gets to its neck.
