Help is just a click away
Danny was bored, it's not something new, the Infinite Realms were not the epitome of fun and the portals had been closed after the fight he had with his parents. It was safer that way, no one could get hurt, humans or ghosts.
That didn't mean the halfa couldn't miss them: his family, his friends, or the life he had before. All he had left were the ghosts, which was fine, but it wasn't enough. He felt unbalanced, unwell.
Clockwork told him it was because of his obsession, his obsession to help and protect was being fulfilled but only halfway. He had enough ectoplasm to last a lifetime but Danny was a human too, he needed to see the stars, to help people. He needed it desperately.
Clockwork noticed this and seeing that the boy could not return to his original dimension, he gave him permission to travel to the DC universe as long as he was careful. It was unlikely that they would attack the halfa there, they were all "special" and Danny would go unnoticed. But the boy still wanted to help.
So he formed a small business. He created a simple app and granted help to anyone who made a request. From saving a kitten from the trees to transporting very heavy packages.
It worked wonders and lowered his stress levels greatly. Danny thought he could get used to it, until people started making stranger requests and before he knew it, the so-called "Justice League" was at his door. Of course, he escaped, although that probably didn't help sell his innocence.
