8. Power Princess

Squadron Supreme is the most underrated comic book of all time. It's a Watchmen-level gem that's hiding under the surface. And Power Princess is a big part of it.

Princess Zarda was raised on Utopia Isle. During World War II, she joined the world's first super team, the Golden Agency. She outlived that team, and became a main member of the successor super team, The Squadron Supreme.

In the Squadron, the monster known as Overmind mind-controlled Power Princess and the rest of the team. After the Defenders freed them, the Squadron decided to take a more pro-active role in problem solving. The team became more and more corrupt, until a battle with a former member cost multiple Squaddies their lives. In the wake of the battle, Zarda disassembled the team. When the dimension-hopping miscreants known as the Exiles popped into their reality, Zarda went with them and joined the team for a while to help save other realities.

Strong, fast, and with some energy projection ability, Power Princess is an all-timer of a Marvel hero, and one who doesn't get her due.
