Codenamed Chris, meaning "Guardian"—but he doesn't protect people, he protects the equipment as long as it still functions.
At eight, he pieced together a functional machine from scrap metal. When the convoy was attacked and the lead vehicle was hit, he grabbed his toolbox and rushed in, cutting the fuel line in thirty seconds and dragging it out of the firing zone. His entrenching tool was always with him, and the robotic arm on his back automatically rewired itself. When his teammates were engaged in firefight, he dismantled roadblocks; when his rifle jammed, the robotic arm had already reached out and reloaded it in a second.
As the Hummingbird mech weaved through enemy lines, tearing open wounds, Chris crouched thirty meters behind it. The Hummingbird handled infiltration and disengagement; he ensured that the mech never stopped due to malfunction.
