Pokemon's First Appearance: Pokemon Gold, Silver & Crystal

Both Ho-oh and Moltres share the exact same weakness but that's their only real similarity. Ho-oh has 100 points more for its base stat total than Moltres, and can actually take advantage of Moltres' weakness to Thunder attacks. Ho-oh can also learn an assortment of moves which makes it a threat to a handful of different Pokemon. Considering Ho-oh is the "guardian of the skies," it only makes sense that it's a pretty powerful Pokemon.
