Hello! I just discovered this subreddit and it seems perfect for what I've been focusing on recently. Hopefully this is the right format or what have you.

Backstory: My friend and I played a ton of City of Heroes back when it was active (rip). We eventually developed backstories for some of our characters, and eventually those backstories turned into an idea for a comic book.

Short version: The comic is focused around a group of characters called The Legion. For our purposes, think of the X-Men or the Avengers. Some founding members, but eventually a rotating roster. What I've been doing recently is trying to flesh out our roster of founding members. I like the characters we have but I want to know if it's too big, if there's some archetype we're missing, etc. Basically I'd just like advice about the roster as a whole and whether there's something missing. Here are (super) brief bios and some analogues to help:

• Power Line: Co-leader. Scientist. Can control electricity. Intelligent, tends to think before acting. Reed Richards minus the lack of social intelligence. The brains of the group. Can be calculating at times but isn't dispassionate.
• Giganaut: Co-Leader. Can absorb kinetic energy and use it as physical strength. More of a brawler, prefers action but lacks the finesse of a martial artist. Strong-willed, the muscle of the group. Basically Strong Guy's power, though personality-wise he's more like Wolverine.
• Force/Bubbles: (I can't decide on a name. The latter would be tongue-in-cheek). Can create forcefields of any shape or size, either centered around him or as separate objects. He can control them, throw them like a baseball, etc. Something of a daredevil. Johnny Storm-esque.
• Creature: The youngest in the group. Can transform into any animal. He takes on attributes of that animal when reverting to human form. (So if he turns into a cheetah, he's extra fast for a bit when he's human.) Also a borderline superhuman martial artist. Gifted, well-versed in multiple styles, etc. Uses both his martial arts and his power to overwhelm opponents. A mix of Peter Parker and Beast Boy.
• Geomancer: The financier of the group. Independently wealthy. Can control any natural terrain with which he's in physical contact. Tends to walk barefoot for this reason. Eventually learns to control things like metal. He's well-reasoned, intelligent, though not a scientist. His power is heavily Avatar-based. Personality wise he's closer to Tony Stark minus the inventing.
• Spectre: She can become intangible or invisible, but not both. Can fly and eventually obtains cold powers. Limited psionic capabilities. Tends to be the caretaker of the group, especially for the young ones. Violet (from the Incredibles) with a little Jean Grey.
• Pocket: Can create localized fields of high- or low-gravity. Can also open portals to her own pocket dimension; useful for things like storage or teleportation. Sort of Ramona Flowers in personality.

We originally just had the first six, but it bugged me that Spectre was the only female and that she was sort of typecast as the mother of the group. I'm happy to go into more detail about specific characters, but basically what I'd like to get now is feedback about the overall group. Is something missing or do they seem like a well-balanced bunch? Obviously I'm not pitching the next big Marvel comic, but for a plain ol' Silver Age-style comic do they seem diverse enough to carry a story?

Feel free to ask for more information, I'm not sure if this is the right way to post what I'm looking for. Thanks!
