Mecannibal

The Mecannibals are aliens from the Generation 1 continuity family.

Mecannibals are mechanical lifeforms that "eat" other mechanical lifeforms. They are faintly reminiscent of spiders, except with only four spindly little legs attached direcly to a rotund red body, which appears to be mostly toothy mouth, below a pair of malevolent yellow optics.

Mecannicals reconstitute their prey back into their component parts (or at least, PARTS of their prey), which they have been known to sell on the black market to unwary or unscrupulous buyers.
