Gitan

Gitan appeared in 1986 TV series called Choushinsei Flashman. Gitan is a Beast Warrior created by Lee Keflen with a massive jaw and protruding tentacles it can spit out to eat other alien lifeforms. Keflen decides to use this Beast Warrior to eat all of Sir Cowler's Alien Hunters in order to increase it's power, seeing this as a necessary sacrifice for conquest even with the potential of Cowler using Keflen's own secrets against him. During it's initial assault, it is prevented by Cowler and the Flashman from eating the Alien Hunters; but in the midst of the troubles leads to one of them, Gerao, to be so wounded that it is found by several children trying to find aliens to befriend. With Bun's assistance, Gerao tries to escape from the Beast Warrior, but it ultimately catches up and knocks down the Flashman. Gerao defends Bun protecting him but does so in ultimately sacrificing it's own life, being eaten by The Gitan and growing to a giant size in powering up. The Flashman immediately activate Flash Titan, nearly getting Titan Boy eaten before slicing the Beast Warrior with the Radial Cutter, then destroying it ultimately with Great Titan's Titan Nova.
