Chairman Keaton
From Wikitroid, the Metroid wiki
Chairman Keaton is an official of the Galactic Federation pictured in the Super Metroid comic series. He appears as a moderately tall green alien with Martian-like feelers. His rank in the Federation high-command is unknown, but he wields considerably high authority over the Federation Police and is seen giving orders to Chief Hardy.
Keaton also appears in the Metroid E-manga, this time as a member of the Federation Congress instead of Chairman. In one scene, Keaton is seen questioning the Galactic Federation's rise to military power (fearing that they are "no different than Space Pirates"), and later speaks his mind with the Chozo, who share his sympathy.
As Keaton is yet to be referred to in any of the Metroid games, his character is considered non-canon.
