There’s marketing punch with Hercules, as well, hence why its a strong contender. The Mercury ‘connection’ to Hercules being a winged coaster, as Drachenwolf previously suggested.I don't know a demigod from Demi Moore.
Remember, you're dealing with BGW, who has put more twists on historical references than Chubby Checker. I'm sure some of them were disappointed to learn Leif Erickson never traveled to Rome.
I agree... Gladiator, Trident...along those lines. But recognizable enough you don't have to Google it. They'll want a name that's got some chutzpah for the "rock jock" style commercials (probably using some of the teaser lines we've seen)....
..."Escape Pluto's underworld and be immortalized in the Garden of the Gods...as the Ultimate Gladiator! Opening Spring Busch Gardens, Williamsburg...."
The joke wasn't that funny you had to repeat it twice ?
