Cheif- A new guy with powers like Cap who was frozen before Cap to test the process. He is unfrozen in our time and goes through rages with the differences. He becomes the unofficial leader.
Pym as Ant-Man looking like Giant Man- Official leader and classic leader.
Wasp- Female lead and classic Avenger.
Namor- The old solider and experiance on the team.
Rick Jones' Captain Marvel (if he's still alive)- Somewhat of Sentry's "too powerful" role, but is basically fufilling Rick's younger side that never got to join the original team.
Elektra- The wild card the team isn't sure about.
Hornet- Spidey's old identity from the Identity Crisis years, but with a new identity.
Venom- Briefly on the team, but gets thrown off for former treason.
Merry Christmas and a Happy New Year
