I think a Metroid pack would be great.
Samus
Choose if you want to play with baby metroid as a sidekick or no sidekick (changes deck slightly). Samus would have a mechanic similar to Sinbads Voyages but with Chozo statues instead. Each Chozo statue would only upgrade a certain attack/defense card and will put any card that is upgraded due to this statue from the discard pile back in her hand (for example: Chozo Statue to upgrade missile cards to super missiles cards, all missile cards in your discard pile are returned to your hand). Samus will have both melee and range attacks.
Maybe if you choose to play with the baby metroid sidekick you start with all Chozo statues already in your discard pile, but you will also lose if the baby Metroid is killed.
Team of Metroids. Get stronger each time an attack does damage (sucking the energy from their opponents).
Ridley with space pirate tokens.
If a fourth character is needed, pick on of the following:
Chozo ghost.
Sylux.
