Team Ninja did not create the story, it was done by Yoshi Sakomoto, who IS Metroid
Essentially, the character is what Sakomoto had envisioned, and many fans of the series had different ideas and are complaining and blaming Team Ninja and etc, when it's really been the idea the whole time. Metroid Fusion definitely was similar in character to Other M.Following the original Metroid, Sakamoto has directed all Metroid games produced internally by Nintendo except Metroid II: Return of Samus. These are Super Metroid, Metroid Fusion, and Metroid: Zero Mission. He also supervised the production of Retro Studios's Metroid Prime series. Sakamoto also directed Metroid: Other M which was co-developed with Team Ninja.
Fun side fact. Yoshi Sakomoto is who Yoshi(the Dino) is named after in Mario.
