Suggestions:
Shiprex
Sounds like "shipwrecks" but also evokes imagery of a dinosaur. Sure, it's the wrong dinosaur, but if you're bothered by that, "rex" means "king" and it's not like T. rex has very specific etymology to begin with. It's similar to bughouse's "Shiprekt" even though I tried to veer away from it, but I figure it's an alternative for those who are bothered by the memetic reference in that other name. In fact, you could even give this a nickname like "ShipREKT" like how people use nicknames like "HeraBOSS".
If bughouse somehow likes this name better, I'm willing to share credit or hand it all over in favour of the other suggestion:
Disastoar
The main reason I made this post now instead of waiting to talk to bughouse about the other name. It's the kind of cringe-worthy cheesy name that litters the Pokemon namespace. Also, full disclosure: I may or may not be biased by Final Fantasy VI. I can only say that I consciously thought of this name before consciously remembering a certain enemy...
But yeah, these are apparently the best I could come up with. I could never make much headway in this stage :(
