Meat Quest: Monster Isopod

I've thought about possible solutions to this problem for years, while I'm not necessarily opposed to sapient hyenas hunting sapient zebras, I feel like there should be some other, less ethically and morally questionable options available.

Another possible option I considered a few times over the years was arthropods. I didn't do much with bugs early on, even though when I was young I was fascinated by them. I'm not sure where I got the idea for giant isopods, but they seem like the sort of weirdness that fits with the Geoterra Project.

This is the adult form, a monster about 1.5 meters long and protected by heavy chitin armor plates--the child form will be smaller and cuter, but the super form will be much larger, and armored with biosteel plates that'll give the hyenas and their ability to spit energy beams a real challenge. The internals will be a bit different from real-world bugs, with more advanced organs, and meat that would be comparable to pork once cooked.
