Nintendo Comics System

From Wikitroid, the Metroid wiki

The Nintendo Comics System was a comic series published by Valliant from 1990-91. It occassionally featured Metroid information or a story. The significance of these comics includes the first depicted fight between Samus and another bounty hunter ('Big Time' Brannigan), the first reference to her having done time with the Galactic Federation Police, the first consistant appearance of Samus as a blonde (Metroid did not have a set color palette for her), and what appears to be an early Zero Suit.

Samus, Mother Brain, Ridley, and Kraid were all in the spin-off Captain N: The Game Master.
