So I'm creating a superhero team

So far I have characters for the following roles

Leader

Mage

Stealth guy

Guy who's out of time

The one from another realm

Powerhouse

I feel like there's important roles that havent been filled. What other roles could I make characters for?

What about Mr. Too Much Cologne Wearer, or Golf Ball Washer Guy?

Wait, that is a different team. Real American Heroes! If you get the reference...

This is a bit late, but I have some archetypes you mind want to consider adding onto the list.
They include:

Billionaire with dead parents

An archer on the team

a female on the team

an alien on the team

Cyborg/android/robotic person

I would throw a guy with imperfections to the team. Or make one of the above have a major flaw.

When I say flaw I mean something like:

- Being almost evil.

- Heaving an adiction, perhaps alcohol, perhaps gambling, or sex, it can be anything... Whatever motivates you the most.

- Heaving a personal agenda. A secret that motivates him, that eventually puts the team at risk.

- Heaving some rare disease. Perhaps he/she has to take his medication or else?

This is off the top of my head. To my understanding imperfections make for interesting characters.

Probably you are not interested in my answer by now, since you posted 3 years ago, but...

How did your project turn out?
