This may sound insane, but Wonder Man is almost more over-powered than Superman.
This Marvel hero can do almost everything Superman can do, but also has abilites like shapeshifting, teleporting, giving his powers to other individuals and being immortal.
There’s literally nothing that’s impossible, hence the name, and perhaps why he’s not as popular as some of the other Marvel heroes.
No one would want to see Wonder Man on-screen just kicking ass with no adversity.
