Macer (Earth-5125)

Doctor Macer was the lead medical doctor and surgeon of the Mjolnir.

Biography
Macer became a Carrier and citizen of Zion, eventually becoming the lead medical doctor and surgeon of the cruiser Mjolnir.

After the Mjolnir located the remnants of the Nebuchadnezzar, Macer was able to find an unconscious Ludens, whom she sent to the ship's medical bay to be treated alongside Durin. There, the doctor studied both of them, discovering that Ludens still seemed to be travelling between parallel dimensions despite being physically in the real world.

After Durin woke up, he was brought between Macer and Captain Bane, who questioned about what happened to him when he and his fellow Carriers were in the Matrix. Durin lied and said he didn't remember anything, which made both Macer and Bane suspicious of him.

During a meeting between the Mjolnir and Nebuchadnezzar crews, Macer was alone with Durin in the ship's medical bay. She was preparing a serum that would allow him to relax and remember what happened with him. He then started a monologue about life, and she realized he had betrayed them. Macer attempted to use the serum on his neck to kill him, but she was too late, and he slitted her throat, killing Macer.
