It depends on the specific fanfiction. In some stories, Superior Iron Man might be more powerful because he's willing to push the limits of his technology and his morals further. But in others, Iron Man could be more powerful due to his experience and his ability to work well with others.
Another idea is a time - travel fanfiction. Blue Beetle and Black Beetle could be sent back in time to a crucial moment in their predecessors' lives. They then have to make sure not to disrupt the timeline while also trying to gain some knowledge or power that can help them in their present - day battles. This would allow for exploration of their origins and how they've evolved over time.
The story where Blue Beetle teams up with other heroes like Booster Gold is really good. It shows his ability to work in a team. They have great chemistry together and face some tough challenges side by side. It's a story full of action and humor.
The Blue Beetle's origin story typically involves a young man named Jaime Reyes. He comes across an alien scarab which bonds with him. This scarab gives him superhuman abilities and a powerful suit of armor, making him the Blue Beetle.
