OSS Sentinel

Sentinel, or better known as 'Cent',  is an  OSS (Omni-Situation Soldier), a combat 'android' that was the last prototype created in the research process to achieve the first synthetic entity capable of generating an Aura, aka Penny. While lacking the Aura capabilities of its ultimate product, Cent's more robotic assets, mainly the versatility of its  modular  weaponary  and hydraulics-enhanced strength, make it a highly effective member of the security team within Ironwood's Faction, mainly bodyguarding Penny when she is back in the labs.

Appearance
As an android, Cent lacks a gender, but its body was designed after the male anatomy and its general silhouette is that of a towering man with bodybuilder proportions. Unlike Penny, whose robotic nature is more subtle, Cent is immediately recognizable as a robot, with all four of its limbs being mechanical, similar in both armour and colouring to those of the Atlesian Knight-200. Cent's arms are unusually slim for its build; this was deliberate so that it can slot and integrate them into its modular weaponary to allow for their usage. In contrast, Cent's legs are much more bulkier, encased in armour plating, especially near where a normal human would have 'feet'. Instead, Cent has elephant-like circular stumps, which are further flanked by miniature pile drivers on each side in order to allow it to secure itself to the ground.

Cent's face would have been quite remarkable for its closeness to that of a human's, if not for the metallic complexion devoid of any disguising skin, the two halves of a V-shaped visor welded to the sides of its face and the total lack of hair, brow and all. Other than that, Cent has human features such as lips, facial muscles, eye lids and rather mesmerizing eyes, due to the brilliant LED blue they emit, as well as the visibly pulsing circuits on the iris.

As a combat android, clothes are not part of Cent's programming and thus it generally only wears the armor customized to it. This takes the form of heavy shoulderpads, greaves a sealed chestplate and a helmet that deploys from the back of Cent's neck and fits seamlessly with the pre-existing visor, all of them in the sleek white Atlesian aesthetic.

Personality
Cent's personality is highly variable due to its nature as a programmed machine, depending on the mode that its overall systems are currently in. Switching between them based on a specific series of voice commands along with facial recognition, Cent possesses a total of five shown modes: Maintenance, Security, Bodyguard, Search and Destroy and Combat.

The Maintenance mode is analogous to a person being put under sedation anaesthesia, being able to communicate while not actually being conscious. As engineers take a look at Cent's systems and perform upgrades and maintenance, Cent will automatically give feedback in a monotone voice that communicates in a highly detailed, computer-like style. Cut off from its locomotive and combat functions, Cent in this mode can be best described as wholy obedient and purely reactionary.

The Security mode is Cent's primary mode when it has to guard the facilities and labs. Respectful to its colleagues and suspicious of outsiders, Cent is blunt, no-nonsence and unyielding to persuasion. Indiscriminate, it does not leave any suspicion unchecked and will never attribute anything to 'just its imagination'. Possessing a more powerful logic simulator, Cent is able to command other Atlesian robots, but gives way to the more 'superior' humans.

The Bodyguard mode is activated whenever Penny comes home and while maintaining most of its priorities in its Security mode, Cent's number-one function is to look out for Penny at all times. In this role, it's personality takes a very human-like turn as it acts more like a protective big brother, communicating with Penny in very gentle tones and comforting her whenever she feels troubled, even if sometimes it cannot fully comprehend her circumstances due to their differences. However, should Penny go out of line, Cent becomes more stern with her
