Suggested by iKnowledge Joker returns to fight Spock. Spock has some decent super strength at his disposal along with his energy blaster. It won’t be sent to stun in this round so that helps him a great deal. A single blast would deal a lot of damage and he also has heightened physical abilities which will help him deal damage and dodge counter blows. I think this combo will be too much for the Joker. Spock wins.

Good work. Have you considered reading this: https://www.reddit.com/r/whowouldwin/comments/269gdp/spock_vs_joker/ for advice?
Thanks. I hadn’t seen this thread before, but it’s certainly interesting. It seems like the general response there is that Joker would win although both fights are pretty circumstantial. With prep time I also think Joker would probably have this, but in a fair fight Spock should end him pretty quickly.
