Mothership Zeta Crew/Characters

The Lone Wanderer/The Commander

Four Star Baddass: He's the Player Character. Probably by the time you pick up the mod you're around level 20 with an arsenal to wield and some power armor to boot. If you played the other addons or mods then you have more armory than an actual armory.

Badass Army: The TSC Marines are descended from the Enclave and have every bit of their training.
Elite Mooks: Really, the average TSC Marine would be considered this by most factions, given their Enclave training. If the TSC Vegas stats are anything to go by, the average grunt is as well armored as a Legion Centurion or NCR Veteran Ranger. Thunderfist troops and the Black Guard are even more so. Not so much in Fallout 3 stats, though, where the very same Marine armor has barely more protection than the armored Vault jumpsuit and Thunderfist Armor has barely more protection than leather armor unless you get one of the mods for the mod that boosts armor stats.
Praetorian Guard: The Thunderfist Black Guards.
More Dakka and Beam Spam: The bog standard Assault Rifle in the game has 30 rounds and goes through it in seconds, add in the occasional grunt with a disruptor or atomizer. However, heavier units usually use alien weaponry, miniguns, or gattling lasers.

Magnificent Bastard: More like Magnificent bitch, aka the 'Red Rose', an Inquisitor of the Western Brotherhood of Steel.
There Was a Door: How the Western Brotherhood of Steel Assassination Squad tries to kill you, the Player... and they did it with a gunship based off of Pre-War design... with a laser turret in the front.
