Eternatus Cosmic Giant Coloring Page

Eternatus in its Cosmic Giant form is one of the most visually striking legendary Pokémon, with its skeletal dragon appearance and otherworldly energy radiating from its body. The intricate details of its ribcage structure, glowing core, and flowing energy tendrils create plenty of interesting areas to work with. This design gives you the chance to experiment with both dark, cosmic themes and bright, glowing accents.

What colors work best?

The official palette uses deep purples and magentas for the main body, paired with bright toxic reds and pinks for the glowing energy core. Dark grays or black work well for the skeletal structure to create that shadowy, menacing look. You could also try a blue-and-teal cosmic variant for a different energy feel, or go with green and yellow for a more radioactive appearance. The contrast between dark body sections and luminous energy areas really makes this design pop.

Did you know?

Eternatus is known as the Gigantic Pokémon and can cause the Dynamax phenomenon in the Galar region. In its Eternamax form, it becomes the largest known Pokémon at over 300 feet tall. The design draws inspiration from cosmic horror themes, with its exposed skeleton and core resembling something between a dragon and a cosmic entity from space.

How to color this one

Gel pens or markers work particularly well for the glowing energy sections, as you can layer bright colors over darker backgrounds. Start with the skeletal structure first using grays or blacks, then add the energy core with your brightest colors. For the glowing effect, leave some white space or use a white gel pen to add highlights along the edges of the energy streams. If you’re using colored pencils, try blending from dark purple outward to hot pink for a radiation glow effect.

Who’ll love this?

Older Pokémon fans who appreciate the more dramatic legendary designs will enjoy this one. It’s also great for anyone who likes cosmic or sci-fi themes beyond just Pokémon. The detailed linework makes it better suited for patient colorists who don’t mind spending time on intricate sections, rather than quick coloring sessions.
