Lowe (clone)
This clone of Lowe was bred to protect the Swarm's nucleus embedded in the Fourth Doctor's mind.
Biology
Due t0 the hasty measures taken for its creation, the clone was a short-lived "photocopy" created by the Kilbracken cloning technique. He had a maximum lifespan of eleven minutes. His mind contained memories and experiences of the original. His outfit and gun was cloned as well.
Like the original, the clone had been infected by the Swarm. (DW: The Invisible Enemy)
Biography
Origin
In the Bi-Al Foundation in 5000, the Fourth Doctor resisted attempts for the Swarm to conquer its mind so that the Swarm could reach out through time and space. Lowe had demanded to Professor Marius to hand the Doctor over to him. When the Swarm made "contact" with Marius, he told Lowe about the cloned Fourth Doctor and Leela that had been shrunken down and were going to destroy the Swarm's nucleus inside the Doctor's mind.
Infuriated, he had Marius clone him to hunt them down. (DW: The Invisible Enemy)
Inside the Doctor's mind
Marius used the Doctor's relative dimensional stabiliser to shrink the clone down and inject him into the Doctor's brain. When he reached the Doctor's mind-brain interface, Leela had sensed his arrival and fought him. In the struggle, Lowe had fatally wounded Leela, but was consumed by the Doctor's phagocytes.
