>>10075938MMC would probably fit in just fine with either NA or MS to be perfectly honest. It's bigger than Hasbro's for sure but I think either works. MMC's is definitely higher quality and the aesthetic works a bit better but Hasbro SkyLynx is also fun and a great chunky toss-around toy. You can't go wrong with either but I like me some SkyLynx so I got both. I'd personally lean towards pairing MMC with legends though because I don't mind him being larger than the show had him and I think the alt modes scale better.
You'll have to forgive my MMC SkyLynx's drooping head. I took some screws out to check how easy it would be to swap the LEDs and haven't put them back in.
