Star Paladin Cross

Star Paladin Cross is a possible companion NPC in Fallout 3. She is a member of the Brotherhood of Steel and answer directly to Elder Lyons. She used to protect James on his missions, so she is more than willing to fight aside the player. However, she will only join you if you have positive Karma and will leave you and return to the Citadel if your Karma drops too far for her liking.

Equipment
Cross' default equipment includes a Super Sledge, Laser Pistol and the Brotherhood of Steel Power Armor. Like all other human NPC, those pieces are not tradeable. Even though her default equipment does not include headgear, she will wear any helmet given by the player.

Cross can be given a variety of weapons and given her Brotherhood training she will switch between weapons to fit the situation. She is effective with most weapons (Plasma Rifle, Missile Launcher, Flamer) and she will wear any armor better than her own.

She also seems to pick up dead enemies' weapons and ammo on her own. Checking in inventory after awhile and you might notice a whole bunch of guns, which you can sell. Her starting weapon is a Super Sledge and a Laser Pistol with infinite ammo.

Combat
With default equipment, she prefers close combat.

She can apply stimpaks on her own during combat. Even though she regenerates to full health after every fight, in the thick of a tough battle she will use stimpaks if needed.

Appearances
Star Paladin Cross appears in Fallout 3. She can be found in (or near) the Citadel Laboratory.
