Let's see...
Nico Minoru - Aggressively cheerful magical girl. Her love for cute clothes and bright colours strains even Molly's patience. Summons her staff by pricking her finger with a small sewing needle, but only if she absolutely has to because she can't stand the sight of blood.
Mercury - Similar to the T-1000 not just in powers, but personality as well. Basically turns into Catherine Weaver from the Sarah Connor Chronicles: Cold, calculating, and fiercly protective of those she cares about. X-Force's most ruthless and effective assassin.
Danger - Still taking a stand against oppression and social injustice, she adapts her methods once that righteous anger in her heart has been replaced by boundless love and understanding. Spends her time making experimental trance music, running blogs, using her holograms for political activism, and engaging in free love.
