Sneaky bump? ;D
I will always adore the original. Not just for nostialgia, but the beauty of the lines in it that were carried into the future mottos. It felt truly villainous.
I care little for the Hoenn & Sinnoh mottos, they seemed like cheap re-iterations of something that was great.
The Unova theme, however felt like a fesh take on something and actually felt new - the Black/White references as well as the Fire/Thunder/Reshiram/Zekrom references felt fitting and not out of place.
