Backstory
Sometime in Websitia's past, one of DrWilyII's trusted Generals rebelled against him and launched an independent bid for global conquest, only to be defeated and presumed destroyed in a climactic battle with borockman.
That "presumed" part is kinda important.
Many years later, due to a completely unexpected event, that General - Robo-Ky - was reactivated and managed to drag his shattered body to the ruins of the Mobile Crusher Parlour, where he stumbled across the body of a Reploid presumably abandoned by the Doctor, completely intact save for an almost complete burnout of it's central processor. Never one to pass up an opportunity, Robo-Ky successfully transferred his core program into the Reploid's body and was reborn at last.
His initial plan was to remain hidden and slowly work towards toppling DrWilyII, but that plan was sunk when he witnessed a pod being dropped into the MCP ruins as he was preparing to leave. The pod contained an unfamiliar Copy-Bot and, struck by an uncharacteristic sense of duty, he spent some time reactivating the Copy-Bot - Ruby - and eventually, reluctantly, agreed to let her tag along with him. Not willing to reveal himself out a fear that Ruby might recognize his name or somehow out his existence to the Doctor, he decided to pretend he had amnesia and took the name "Kai" from the serial number engraved on his armor. The two eventually ran into members of Websitia's Resistance and joined up with them.
Hell-bent on revenge against the Doctor and his forces, "Kai" continues to maintain his masquerade as an amnesiac while hiding his true identity and intentions - whatever they may be - from his new travelling companions.
Personality
Kai tends to keep to himself for the most part, preferring not to speak at all unless he has something to say, and even then he tends to deliver his messages in the bluntest, most concise way possible. He's marginally more talkative with Ruby, not that you'd know it since most of those conversations take place over a private network link between the two. His body language and facial expressions are equally subdued, especially around the Resistance members he's currently travelling with.
Robo-Ky was originally almost completely emotionless and approached everything from the cold, logical position of the machine he was, but something seems to have changed in him since his return to the world. It's yet to really reflect itself in his outward demeanor (not that anyone would pick up on it unless they were close to him prior to his presumed destruction...) but privately he's become more prone to long periods of self-reflection and seems to be affected by the lives of those around more than he was before, if his odd display of compassion towards Ruby is any indication. Whether this will lead to a full-on change of heart or not is anyone's guess.
Abilities
Kai hasn't really had the opportunity to fully test the physical limits of his new body, but he's definitely had an upgrade from his previous form. He's immensely strong, easily capable of tipping a People-Carrier with one hand if the situation ever called for it, and far quicker on his feet than he used to be, though he's not quite gotten used to the increased mobility, still appearing to favour a rigid, defensive style when it comes to combat.
Thanks to his familiarity with DrWilyII's coding style, he's exceptionally skilled at hacking into the Networks controlled by the Doctor without alerting anyone to his presence while doing so, and this skill translates to other networks too.
Thanks to the group he's travelling with, and Ruby's mad-science approach to weapon design, he's recently acquired a customized gauntlet that incorporates both a Bagh Nakh (a set of Tiger Claws) and a Pata (a gauntlet-mounted sword) into one easy to use, easy to wear tool. Ruby's influence shows through, though, as the retractable "sword" portion of the weapon is actually a chainsaw. Some of his forms, especially when using the Claws, seem a little sloppy, almost as if he's trying to emulate things he has vague recollections of from sometime in his past. That said, his approach to fights combines his superior physical capabilities with, where applicable, an equally vicious assault over the Network, overwhelming his opponents with as much a mental assault as a physical one.
Weaknesses
Kai lacks ranged offensive capabilities at present, and is unwilling to fully commit all of his experience and.....unsavory tactics to combat to try and avoid tipping anyone off as to his true identity. The recent addition of true emotions to his programming has unsettled him somewhat, and he can sometimes freeze up or become dangerously unpredictable while he tries to process the unfamiliar sensations they can evoke in him. This will likely become less of an issue given time and acclimatization.

[spoiler=Ruby]Ruby
Age Unknown (designed to resemble a 14-year old)
Female
Copy-Bot
5'2''
Backstory
The de-facto leader of the Team RWBY Copy-Bots (or at least, she was), Ruby was moved to the Mobile Crusher Parlour and kept in stasis for reasons unknown. She was discovered and reawakened by the mysterious Reploid "Kai" and decided to tag along with him until such a time as she could return to her proper place at the Doctor's side.
When the pair ran into members of the Resistance, they opted to join forces with the group, though Ruby was initially rather hesitant to do so, having been programmed to believe that the Resistance were the "Bad Guys" in the ongoing war on Websitia. Eventually reaching the conclusion that there are two sides to every story, she's currently travelling with them and reflecting on what her role in this conflict should be...
Personality
As per her apparent inspiration, Ruby is a bright and almost perpetually cheerful girl who's more than happy to try and befriend everyone she meets. Unfortunately, she's also a bit of a motormouth and has a habit of blurting out sensitive information without really thinking about what she's saying. She shares the real Ruby Rose's love of cool and unusual weapons and her first instinct upon seeing a new one is typically to fan-girl over it regardless of the affiliation of it's wielder.
This is at least partially an act, as she's confused over her apparent abandonment by the Doctor and her treatment at the hands of the Resistance members she's met, which runs completely at odds with what she'd been told about them. She also dislikes being idle, and has developed something of a phobia of enclosed spaces. Additionally, she misses her "sisters" in the RWBY unit and is attempting to convince Kai to open up a little more to their new companions, with limited success at present. She's still a little wary of his recalcitrance, but figures since he's been nothing but helpful to her, he's probably trustworthy. She also seems to look up to Touko as a sort of "Big Sister" figure, if the fact that she made her new coat resemble one Touko lent her is any indication.
[spoiler]The truth of her abandonment lies in that fact that DrWilyII was too faithful to her inspiration while programming her personality. She's loyal enough to the Doctor, to be sure, but Ruby Rose is practically defined by her desire to be a hero and change the world for the better, to the point where subverting Ruby's desire to do the right thing would require an almost complete personality re-write, regardless of how strong the "Obey Wily" part of her programming is made. With her current circumstances causing her to give serious thought to who the real villains in this war are, she may not be a Wilybot for much longer....[/spoiler]
Abilities
It may just be a quirk of her construction, but Ruby is fast. She frequently blurs when moving around, and is such a motormouth that she often has to be asked to slow it down to something like 500 words a minute or something somebody can understand.
According to her, her power core is something called a "Kinetic Conversion Engine", which she's said makes her body "like a giant elastic band" but it's anyone's guess what she actually means by that. The truth of it is that it's an experimental self-perpetuating power source with no clear limits on how much energy it can actually produce. Essentially, when she starts moving the energy produced by the motion is funneled back into her core and recycled to keep the motion going, allowing her to reach truly ludicrous speeds in almost no time at all. When she slows down to a more reasonable pace, any excess energy she's built up drains into some kind of reserve tank that can be drawn on in times of crisis, or used all at once for a short burst of insane speed or a single, massive physical strike. Doing so leaves her temporarily drained until she can recover her strength.
Originally, she was equipped with a replica of Ruby Rose's "Crescent Rose" weapon, a combination Scythe/Sniper Rifle, but she no longer has access to it after being abandoned. A lucky find at a recent rest-stop has seen her acquire a pair of batons that shift into War Picks with a simple mental command. While not the same as her beloved Crescent Rose, they complement her "hit-and-run" fighting style, and the Picks can be used to disarm opponents if they manage to negate her speed advantage in combat.
Weaknesses
Similarly to Kai, Ruby currently does not possess any ranged options for offense, but her speed and general approach to combat make her a far trickier target to pin down during a fight.
Beyond that, she's small and seems fairly fragile, and her general "gotta go fast" approach to everything can sometimes backfire on her as her ability to brake when moving doesn't seem to be too good at present, and she's quick to rush into dangerous situations without really stopping to think about the consequences of doing so.
While her experimental core is a massive help in the sense that she technically doesn't require access to recharging pods or E-Tanks to stay active, the exponential buildup of speed and energy it provides can sometimes be a hindrance. As her speed increases it becomes increasingly more difficult for her to make precise movements or stop in a place where she actually wants to stop. The draining process when she finally does slow down is not instantaneous and leaves her in a state of extreme hyperactivity and agitation until complete, and if she opts to expel all of her reserves at once she's left practically immobile and defenseless until she recover enough strength to start moving again.[/spoiler]
