Okay, maybe that title isn't entirely accurate but this piece of artwork from Hyrule Historia (via Kotaku) compares the heights of characters from The Mushroom Kingdom and Hyrule and guess what? Hyrule has the taller characters.
Mario looks tiny in this piece of artwork with Link head and shoulders above him. Princess Zelda is about the same height as Link but Peach also towers over the plumber. But no one comes close to Ganon who is not only taller but wider than everyone else. He's the width of nearly six characters!
It doesn't say how tall Ganon is here so it's hard to compare him to all Nintendo characters. Surely Pokemon's Palkia - who stands at 13.09 metres - is taller. Which begs the question: Who is the tallest Nintendo character? Any ideas, people?
