Superheroes is one of those weird games that can’t be played a whole lot. For one, the only version that I’m familiar with is easy to script, and it’s a hoop game where the difficulty is set totally by the improvisers themselves. That being said, it is a fun little game that is easy to teach people with little improv experience.
The game is a low energy hoop game for about four people (but can still work with three or five). From the audience you get a suggestion of a superhero name and a problem for them to solve. The scene starts with that superhero on stage, doing some menial activity their alter ego might do as a hobby. They then get word of this problem via telephone or Batsignal, or anything else as long as it is portrayed in the scene. Instead of solving the problem, however, they think about this for a while, and says something along the lines of “I can’t handle this, this sounds like a job for ___!” introducing a new superhero, who then enters the scene. The first improviser can say any superhero name they want (meaning it can unfortunately be scripted), and the two of them discuss the problem. Even with the two of them, they still can’t solve the problem, so Superhero 2 calls in number three, giving them a completely new name. This goes on until all of your previously discussed improvisers are on stage, and the last person to come onstage does solve the problem (ex. Duct Tape Man solves the problem of the world exploding by taping everything up so it stays together).
Obviously, as each person gets called on stage they should personify their superhero. If somebody is “Talking Backwards Guy” then they should either say words in reverse order or speak gibberish as if he talks backwards. It really doesn’t matter, as long as they portray that superhero.
The grievance I have with this game is that the conflict is an artificial one. The only rule to the first three heroes is that they aren’t allowed to be able to solve the problem, so they are pretty much irrelevant to the scene and can therefore be literally anybody. You can also give the last superhero a power that is perfectly suited to solving the problem. This all leads to a very real possibility of everything happening systematically rather than organically, which is not how improv should be.
Now, I have thought of a fix to this game. I’ve never tried it, so I don’t know if it actually works, but here’s the idea. Once all four(ish) superheroes on stage, they can solve the problem, but only when all of them work together. It doesn’t quite work if you act out the fix, but rather the superheroes should come up with a plan. If Treeman, Catface, Steelletto, and Astronomurder all get together when all the world’s water somehow evaporated, how do they solve it? Easy. Instead of saying “Astronomurder can just make a bunch of water-rich asteroids collide with Earth, problem solved”, you must include all of their powers. Astronomurder calls down a bunch of meteorites, sure. But how will this not also destroy the planet? Easy. You get Treeman to turn into a giant tree, which Steelletto climbs, and once the meteorites breach the atmosphere Steelletto uses his cool sword legs to slice all the meteorites into tiny debris. Catface brings all her cats for moral support (or leaves one at the top of Treeman’s tree form to inspire Steelletto to climb at heroically fast speeds).
This way, a bunch of seemingly random superhero names can become a team to solve any problem, and only with their powers combined were they able to handle the task at hand. This makes the improv game into one where each person really has to use their head, and allows them to personify really weird characters to boot.
Also, I’m pretty sure Astronomurder is actually a super villain given his name and power. But maybe he wants to destroy the world on his own terms, or get revenge on his nemesis, Treeman, before killing everybody off. This is all stuff that can (and should) be explained in the actual context of the scene.
