Ok so when people say that there are only two fire type Pokemon in the regional dex of diamond and pearl, I think of infernape and rapidash as do most people because those are the two that Flint uses. Then I realized that Magmortar exists and was made in gen 4 so why do people say it's not part of the regional dex? Is it unavailable until after you beat the game? Because if it is I think Flint should still be able to use it nevertheless?
Diamond and pearl are weird. If you look in the regional dex, its just not there. I dunno why they did this, but it just isn't. I believe some other gen 4 evos aren't there either.
