Trappist
Trappist is a doomsday weapon from TRAPPIST-1e. His goal is to rule over all civilisation in the Milky Way. He is powered by a star and he's very proud of his power. He has a 2nd more powerful form.
The symbol on his chest is an upside down pyramid with a sun to represent the underworld. This is a reference to one of the inspirations for his design, Osiris.
2nd form
2nd form coloured sketch. Drawn on paper and coloured in Photoshop. His hood makes him resemble a cobra and he has horn ornaments on it to make him more intimidating.
Trappist's old second form design. He doesn't look too different to his first form but this sketch became the foundation for his second form's final design.
