I don't even know how the translators got this out of Liquefy (the Japanese name for the move). I remember training my Vaporeon in Pokemon Blue and wondering what Acid Armor did, only to be confused as to why acidic armor would turn my Pokemon invisible while raising its defense. The move itself doesn't really make sense as a whole...
What other moves do you guys think were lost in translation?
Haha I was going to bring this up, too. I don't even know why they added the punch part to it considering so many Pokemon that learn it don't even have arms.
They're both silly concepts for a move considering they're entering into a mutually desired battle anyway, but between the two, "Sucker Punch" is less ridiculous. How do you ambush someone who's been fighting you for fifteen minutes already...?
