Beaker is an alchemist, a cold and analytical person all things considered. He loves his family however, and would do anything for them, but he often comes across as harsh. While not having anywhere near the skill of an official patcher, he acts as the makeshift patcher of the Half-Light family. He is dangerous in his own right, often feigning weakness to get the upper hand and was the one who most frequently tried to intervene with Shivers' drug use. When Tusk became more involved and recruited to a higher position within the Jackal ranks, it was Beaker who looked after Foxhound, the youngest. They had a strained relationship, both working through their grief for both Promise and Shivers in their own way. He would eventually be persuaded to leave the Jackals, which he primarily agreed to with the expectation that he would keep Foxhound safe, and that her involvement in this war would likely lead to her death.
