I like Dr. Merrick. He's driven without being careless. He knows that in the event of a nuclear war, he may be the only person left in the world that can advance human genetics beyond where they are now. He's meticulous, detail-oriented, and reports everything to me on a regular basis.”— Vault 87 overseer
Dr. Wayne Merrick is the scientist in charge of the experiments in Vault 87 and according to terminal entries cut from the final game, one of the brightest minds in the field of accelerated evolution.
