The DC Earth Reed Richards challenge
The Richards have been kidnapped by some all powerful cosmic entity or another that wants to toy with Mr Fantastic's life.
If Richards wants to see his family again, he is to subdue the entire superhuman population of DC Earth within 24 months. People he brings under control (by any means) to assist him count as subdued provided rebellion is impossible.
CIS is very much on, so we can conclude Reed will not kill under any circumstances.
He gets an underground lab identical to his own, with all relevant equipment, in some deserted location.
DC Earth is completely unaware of his existence, at least, at first.
Can he do it?
