I'm trying to find a word for something that always beats something else. Kryptonite might be used for something that you always lose to. From Superman, of course.

e.g. Rock is scissors' kryptonite (scissors lose to rock). Water is fire's krytonite (fire loses to water), and so on.

I want to know the opposite word of this "kryptonite". Say between rock and scissors. What word would be appropriate here:

Scissors are rock's _____. Fire is water's _____.

    Do you have a real example you were considering applying this to, other than rock papers scissors? Dec 28, 2019 at 8:33
  • Maybe worth noting that calling something that is antithetical to something else 'Kryptonite' is severely informal and possibly unlikely to be understood by people who have not read Superman comics, or pleasing to those who don't like them. Dec 28, 2019 at 12:55
  • I was making (programming)objects out of these three: rock, paper, scissors for the game of the same name. Each of them would have two main properties. One has the value of ~"the thing that it loses to" -- I named this property "krytonite". The other property is "the thing that it beats". Didn't know how to name it. I wondered if such word existed. Hence the question. :)

    If Rock is the kryptonite, then Scissors must be the Superman, of course. :P

Running the risk of posting something corny: Anti-Kryptonite, first used in Adventure Comics

enter image description here


What does Superman always lose to? Kryptonite! What or who always loses to Superman? Lex Luthor, Mxyxplital (sp), Lois Lane, Crime.


It's been years. But something antithetical is the opposition to the fact. Such as ice is antithetical to fire. Elemental oppositions such as shown in pokemon are a great example of this.
