Hellions is Psylocke (Kwannon), Havok, Wild Child, Nanny, Orphan Maker, Greycrow, and Empath with frequent appearances by Mister Sinister.
Marauders is mainly Kate Pryde, Lockheed Storm, Emma Frost, Iceman, Bishop, and Pyro with appearances from Sebastian Shaw, Callisto, and Christian Frost.
New Mutants is currently starring Boom Boom, Magik, Cypher, Moonstar, Magma, Wolfsbane, Chamber, Mondo, Glob Herman, and Armor.
