Jonathan (copy)

Jonathan was a copy of Jonathan Levinson’s memories and DNA sample. He was first manifested as a hologram, then as a rapidly decaying flesh body, until he was turned into a vengeance demon.

Biography
After magic was returned to the world and rules of magic wiped, Andrew returned to the remains of Sunnydale, where he recovered Jonathan Levinson's DNA sample and personality saved on a USB flash drive. Andrew revealed to the "holo-Jonathan" that he intended to resurrect him, but had been uncomfortable with simply making a test tube baby or a robot body.

Andrew was prevented from actually carrying through with any magical resurrections, but he continued to converse with the new Jonathan in his Oakland home. He offered him the option to be given a robot body, which Jonathan enthusiastically agreed to, requesting to be made taller in the process.

Later, Andrew went to a witch coven party in Oakland in search of a potion that could make a new body, ostensibly for use in his resurrection of Jonathan. However, the potion was not intended to create a new body from nothing, but alter an existing one.

Andrew continued to search for a new body for the holographic Jonathan, but Jonathan felt Andrew was taking his time and was too interested in looking for dates on Grindr. When demon known as The Sculptor approached Andrew with a deal to create a body for Jonathan in exchange for Andrew stealing Buffy's scythe, Jonathan pressured Andrew to take the deal, claiming it would make up for Andrew's past sins. Believing Andrew had carried through on his part of the bargain, the Sculptor provided Jonathan with a body (which was more tanned, muscular, and taller than his original body), but Andrew had in fact double-crossed the Sculptor and informed Buffy of the deal. Upon realizing that the Sculptor's defeat meant the eventual death of his new body, Jonathan accused Andrew of betrayal and fled.

Eventually, Jonathan allied himself with D'Hoffryn, their mutual vendetta against the Scoobies making them ideal allies, as D'Hoffryn restored Jonathan's physical form while Jonathan gave the demon actual wishes to grant to refine his assault on his enemies.
