Introducing Deep Blue, a super intelligent Death Claw synth built out of gen 2 hardware that the Institute created in a failed attempt at efficient weapons in an effort to whipe out the surface. They fed them all sorts of programming to make them very VERY accurate and deadly but they couldn't... quite be the killing machines Death Claws are technically. So the Institute scrapped the project.
This one in particular strategized and outsmarted the Institute scientist and security system after playing several hundreds to thousands of hours of strategy games and plotting.
Somehow they met Geneveve and Mystic and quickly became a second parent to the Nukalurk child and Gen's romantic (or as close they can get being machines) partner.
For the tech history savvy, yes- this lovely death claw synth is a reference to the same Deep Blue chess playing computer that won championships.
