The Thrash-hunters were an unused species from Metroid 1.5. Their insectoid design may have influenced the creation of the Luminoth, in the final version of the game; Metroid Prime 2: Echoes.
"•Thrash-hunters: Standing 8 and 1/2 feet tall, this Alien is a mixture between a Space Pirate and another unknown Alien species. It uses no mechanical weapons but does use its sharp saber-like claws to rip through opponents with ease. It can walk along walls, crawl across ceilings and has a chameleon-like ability to change its exoskeleton color and pattern to match up to its surrounding environment. It is ruthless and cunning, much like Giger’s Alien; it lives to kill and kills to live.
•In addition to its saber-like claws, the Thrash-hunter also can self-destruct when low on health and when in clear and visible danger. The blast radius would kill anything within a 20-foot radius."
