ComBat
From the Super Mario Wiki
A ComBat.
ComBat are a distant relative to the Swooper, but very distant.[citation needed] ComBat live in the darkest reaches of Yoshi's Island, and nowhere else.[citation needed] As such, they may be found circling the Tall Tower, hunting in the Neuron Jungle, or stalking Bowser's Castle. They pose little threat to most residents, as they hunt small things such as Nomadimice.[citation needed] Nonetheless, ComBats will attack anything that gets too close, and are immune to most things other than eggs.
