The strongest is always Arceus using the Flame and Splash Plates, respectively. Not counting him, the strongest Fire-type is Kyurem (while in White Forme) and the strongest Water-type is Palkia. If you are not counting alternate formes at all, then Reshiram and Ho-Oh share the same place as strongest Fire-Type.
