!!Nathan "Ladd" Spencer
* [[ArtificialLimbs Artificial Arm]]
* EmpoweredBadassNormal: In addition to his arm, Spencer has a number of [[RequiredSecondaryPowers secondary bionic improvements]] that, for example, provide armor, weaponize his adrenaline, and more. He looks mostly human, but he is far from it.
* SpellMyNameWithAnS: His nickname is sometimes spelled [[TotallyRadical "Rad Spencer"]].
** The official nickname is "RAD", and is explained as, when he originally lost his arm, he was the first person to be considered and tested on for bionic augmentation. He was therefore the most important part of the '''R'''esearch '''A'''nd '''D'''evelopment department for bionics. When he went into the field, he was humorously given the codename RAD from all his time in the labs.
* SuperDrowningSkills: Spencer's bionic arm is extremely heavy, and almost completely shuts down when exposed to water. Spencer therefore cannot swim in water as his arm drags him down.
* [[spoiler:DeadAllAlong- possibly as the process of creating the bionic arm has been never been explained so if she's truly dead isn't said]]
* [[spoiler:BigBad]]: [[spoiler:Of the sequel]].
-->'''Spencer''': You're not a freedom fighter, you're just like me. A killer.
-->'''Mag''': Then [[StatingTheSimpleSolution why I haven't shot you yet]]?
* BigBad: [[spoiler:Subverted]]
