I just remembered another one, although I don't think it could have been built much later given the name it got: Steel Dragon 2000.
Nagashima Spaland was hit by a dose of ambition and decided to build the biggest, tallest, longest coaster ever - and it still retains that last record 20 years later. Only one coaster built since has a taller lift hill than it. It's one heck of a machine, its second hill is bigger than many other hypercoasters out there. And to build this beast, they went to... Morgan.
Granted, it wasn't a bad choice per se. At the time, they were one of very few companies to make hyper coasters, being behind coasters such as Wild Thing, Mamba, Steel Eel, and Steel Force. For coasters of that size, it was either them, Togo (dodged a bullet there, at least!) or Giovanola, with Arrow having delivered their last Hyper a few years before. B&M was technically in business at the time, but had explicitly rejected working with coasters over 70 meters until the 2010s. So it's not like Morgan was the worst choice available, but... imagine if Intamin had been put on the case, fresh off of designing Millennium Force, and built SD2K as its bigger brother. Granted, it would probably have to be called Steel Dragon 2002 or something like that, missing the Year of the Dragon by some margin too, but... Millennium Force's bigger brother!
Notably, Morgan didn't stay in the hypercoaster game for long after SD2K. They built the Superman hyper at Six Flags Mexico, and a small terrain coaster for Gilroy Garden, and since then, nothing. I think Chance Morgan was a thing for a while, but they didn't produce any coasters under that name, and Chance Rides hasn't built any Hypers since either. Whatever happened to the spirit of Steel Dragon 2000, it didn't stay for long at the company.
