So, this guy isn't really a Fire King, he's in fact a Resonator / Red Dragon Archfiend card! It was used by Jack Atlas in the manga, a few months before the Fire King archetype debuted in the OCG.
However, because of his name, he can be searched by any card that searches a "Fire King" card. You don't really have much reason to do so, though. (Unless you're playing a Resonator engine in your deck, in which case, you do you.)
