If I'm correct about rocket hitting my Hitmonchan because they tried to target a pokemon I don't have, that pokemon would have been Seel. Seel would not be threatening to Sunflora, Mewtwo, Lapras, or Zapdos. It would be a threat to Ninetales. The alternate explanations I can think of are KY does have an affinity for fighting types and may have just found Hitmonchan to be the best I had out of what I claimed, or rocket can't hit a specific pokemon unless they have seen it by battle or other action.
