YES, YES, YES! I FINALLY FOUND ONE! YES!!! YOU, LET ME SAY, ARE ABSOLUTELY, EXTRA, SPECIAL AWESOME!!! FINALLY SOMEONE BRAVE ENOUGH TO PUT HTTYD AND PJO TOGETHER!!!!!!! sorry for screaming, but this just made my day!
I just had a weird thought of a PJO and HTTYD cross over, with instead of Hiccup, its Nico, but that would mean Hades is Stoic, and Will/Percy (Whoever ships what) is Astrid, and Toothless is still Toothless...or his french zombie chauffeur Albert. O.o
