Megara is in Equestria and she wants to get back home. Twilight Sparkle and Rainbow Dash know just the ponydraconequus who can help.

This story is for Infinity Shade. Because why not?

Oh, and it's got FuzzytheWhatzit's sister's pet dog in it as a cameo. Because why not?

This story is a crossover of My Little Pony: Friendship is Magic (both the TV series and comics) with Disney's Hercules, and also kinda with Dante's Inferno, and also kinda with G1 of My Little Pony. Because why not? (You probably don't need to have seen/read them though.)
