This Cashman OVA is based on a short story (3 chapters long) by Akira Toriyama. It's about an alien (who is actually part of Frieza's race!) who happens to crash on earth. He can't go back to his home planet, because he's out of fuel and his space ship uses gold as fuel. And since gold is insanely expensive on earth, he has to make a lot of money now. Therefore he becomes Cashman, a superhero who charges money for saving the day. He takes over the identity of a police man he accidently killed and now he has to deal with strong enemies and an annoying girlfiend. The premise is pretty cool, it's a typical silly Toriyama plot. Too bad this OVA doesn't do the manga justice, they changed too much and cut a lot of stuff out (which is weird, since the manga is already super short). In the manga Cashman has multiple fights, but in the anime he only fight once. Overall this OVA isn't terrible by any means, but they should have just make it 10-15 minutes longer and just adapt the whole thing. If you like Akira Toriyama's style and you want to see a Frieza looking dude fight some bad guys, then you might get some enjoyment out of this.
