Character 15 of 16 -- Jeeves
Essentially the first original character of The Irregulars (as Lucas actually existed before the concept), Jeeves has had the most interesting evolution of the all the characters. While Lucas, as you will see, has pretty much just gained detail, but remained mostly the same, Jeeves has changed wildly.
Jeeves was originally just a supporting character for Lucas, but became one of the most important characters as he is, technically, the inciting incident of the story. The underground, anti-human movement Minerva works in total secrecy on many levels of their society. While many suspect an anti-human movement exists, most do not believe it is a threat as it is probably very small.
This all changes in the mind of Center 5's server technician, Jeeves: Able to handle large amounts of data through interfacing, he manages the security and mass data-handling and, one day, accidentally comes across a batch of encrypted emails. Since he interfaces directly and is vulnerable to data-based attacks, Jeeves has heavy security and decryption methods, so he automatically decodes the messages without even thinking about it - and finds the messages reveal the existence of a much larger anti-human movement than anyone ever thought possible. And that it had deep ties into the council itself, their highest form of government.
Initially, Jeeves' only ally and confidant is his best friend Quint. But he knows he must do something about the movement and must find allies. But where? Minvera is deeply embedded inside even their government. How can he tell who to trust?
Jeeves' design has both changed and not changed. He was originally less detailed before, but so was everyone else. He always had red armor with gray accents, that was just mixed up a bit with some white as well as other color in his new design. He also always had brown hair and glasses, but I'm so happy to have perfected his hair this time around. His new design was heavily inspired by Aigis (from Persona 3) to give him a different looking armor from most of the other characters. His special abilities are directly related to his specialized body frame, but this is important to the story and I won't say much more.
I sort of "humanized" his design with some inspirations from Quint. Quint, who would have a lot of human influences anyway, was always a character I loved to have around Jeeves. Quint is more outgoing that Jeeves, so she provides a great foil to him and helps build his character. Meanwhile, Jeeves' own attitudes bring out more of Quint so you can understand her more. The two characters really develop each other. Quint's influence of Jeeves is seen in that hat of his: She gave it to him (to match his jacket) because she wanted him to stand out among some of the other technicians.
Also, speaking of human, Jeeves' glasses are an oddity that also tie closely to his plot, but (not to spoil it) they relate to his past and his power.
Alright, next up, last one: Lucas. He's been my signature "test character" for years. I've been saving him for last since I drew his partner, Cypher.
