I mentioned because I didn't see it ranked, (and it's speed is pretty close to Typhlosion) not because it wasn't listed in the location. It can also have Flash Fire, which both other Fire types mentioned lack, right, which makes its fire moves stronger (you could even have a teammate use a fire move to boost it). Anyways no worries. Just a quick thought.Yes, the Houndoom is seen in Realgam Tower as Karixrida noted in the OP. While we are on the subject, it is encountered so far into the lategame that it should probably be ranked Bottom Tier unless you absolutely need something to take Shadow Rushes from Tyranitar and the like. Even then there are better Pokemon for doing so that also appear in Realgam Tower anyways. Having the choice of Typhlosion or Entei beforehand would still be a massive viability hit even if it was available earlier.
