Yes I meant special in the special attacking sense, not the other interpretation.
Honestly I think the entire reson these two (because, again, hitmontop did not get the move) got the move is as a joke.
They have 35 base special in gen 1 which was turned into special attack in gen 2-on and, in what I can only presume was ALSO a joke at the time, given 110 special defense.
hitmontop just stole those stats after its creation, these two just seem to be gamefreak having a laugh.
They dont have the lowest special attack for a fighter pokemon (Sawk & Throh are, at 30) and they dont have the highest special defense for a fighting pokemon (there's sevearl by this point) but they're the only one with such a disparity. Hitmonchan was also the only pokemon to natively learn Vacuum Wave, the special attacking version of Mach Punch, despite having no reason to ever use it in DP.
At some point it just starts to feel like giving Shedinja Final Gambit
