Unlike the actual show, the webmasters at Fire Emblem :GGGAWB encourage you to try these myths on your own.

Myth #1 - The red dragon at the end of Fire Emblem: Blazing Sword loses attack power every time he kills one of the player's units.

This comes from a few fans from various Fire Emblem message boards. Granted, I haven't seen it recently, but soon after the game was released, there were a number of fans who claimed this myth to be true.

However, after dousing some of my units in K.C. Masterpiece Honey BBQ flavor, I allowed the red dragon to roast them. There was no difference in the dragon's attack power. It never lowered, no matter who or how many units were sacrificed, but the dragon tipped well for the buffalo wings I provided. Then he complained about the lack of potato salad and cole slaw, and at that point, I had Athos, Hector, and Eliwood boot his scaly butt out of BBQ Dave's. The other customers were complaining about the smell anyway(dragons kind of stink by nature), so he had to go. Anyway, this myth is completely busted.

Myth #1 = BUSTED
