you could always try to cut new facets with a dremel and cutoff wheel, make it a smaller one. but that would be crazy.
sometimes you can just pound a socket onto it but it would have to have little to no taper given how shallow the bolt heads are.

Happened to me. I put a 6 point socket on and braced the socket/wrench with a block of wood and crow bar forcing it (a lot of force) to stay on while turning (filler plug has same problem: https://www.dsmtuners.com/threads/transmission-help.488183/#post-153482868). After this happened to me multiple times I finally put a normal bolt in with a normal head on it (no taper or shallow bolt heads like the original plug has). {Plug specs: https://www.dsmtuners.com/threads/n...in-and-fill-plug-sizes.532142/#post-153785818}.

Or try this one (although I like and have the cheaper Harbor Freight Pittsburg Pro one even though the largest socket is only 19mm {https://www.harborfreight.com/38-in-drive-metric-bolt-extractor-socket-set-9-pc-67894.html}) :

Or last resort (although I wouldn't heat up the aluminum tranny case method):

funny enough I had just finished fighting a stuck fill bolt, come to find out the drain bolt is also stuck. the bolts came off surprisingly easy on the diff and transfer case but idk why the diff bolts are so dam harm

Normally a pipe wrench would be in order, but that skinny head gives no purchase, and virtually no easy access anyway. Do you have access to a welder? I would weld a slightly smaller but regular height nut onto that plug, and try that. Be careful not to overheat the aluminum case.
Otherwise they do make special gripping extractors, although again, such small corners to grab. Ultimately you might have to start drilling it out for an internal extractor. That might get metal shavings in the trans, though a magnet would like work for getting them all out.
Good luck.

Looking at the photo one more thing comes to mind: grind off the cast aluminum “eyebrow” that obstructs the side of the plug. Would make it easier to get an open-end wrench from the side.
Main point: why did they make these so low-profile!!?!??
