Wrestling with a superhero origins story

Since joining the SFABC and the excellent Writers of the Weird writing group, I've written two SF stories which I'm quite happy about. I've collected one polite rejection, which is also ok.

Now I'm thinking about a new story that is actually a comic book superhero story! I'm not a real spandex-clad fanboi, so this is something of a departure for me.

All I've got right now is the gimmick that creates Our Hero. Our Hero is actually a mild mannered nobody-in-particular until they die, and then are saved by an emergency heart transplant. The gimmick is that they receive the heart of a dead superhero!

So far the dead hero is named Aurion. I don't know much about him so far, except he has golden blood, psionic powers and he's dead. Oh, he's also from somewhere in the EU, because he's a member of a Euro supersquad. Other members

• Bruit - think Thing, but French. "Bruit, le smash!"
• Accelerondo - think Flash, but Italian.

Need more Euros, right?

ps - don't take this too seriously!
