Sentinel

Imperial Sentinels are Imperial robots used as common battlefield units during the Trans-Galactic War and War for the Chronicle Timeline.

Description
Older models of Imperial Sentinels were bullet-shaped hovering robots, meant purely for security, with a single cannon in their torso, often white in color, although elite red variants existed. Current Imperial Sentinels are large humanoids with a rather bulky torso, covered in dull off-white Imperialite platings over their major limbs, with a flexible armor mesh over its other areas. However, this mesh was not present in the initial humanoid model, the IS-3. The current humanoid model, the IS-3a, has two heavy plasma cannons, one on each arm, which can retract and fold up into usable hands and other tools, such as energy blades. A single red optic is visible in their facial area.

Capabilities
Imperial Sentinels are strong and durable robots, loaded with shock absorbers, armor layers, energy dispersers, anti-nanite systems, anti-EMP outlets and armor, and other defenses present on most military-grade assets. They possess great physical strength, able to easily overpower most organic beings and crush various metals, although not the likes of Imperialite. They can run at high speeds, outrunning some vehicles and most organic species. Their main armaments are their semi-automatic heavy plasma cannons, which could wreak havoc upon unprepared and unarmored forces. These rounds could become explosive at the cost of firing speed, which would be reduced. These cannons could also be removed and replaced with other weaponry, such as flamethrowers, missile launchers, and Dark Energy guns, which were a common central gun on the cannon arrays of standard Sentinels. When needed, their cannons could retract and rearrange into gripping appendages, resembling basic Human hands, but larger and with great strength. They can also deploy energy blades for melee combat, or other tools, such as welders. Similarly to other assets on both sides of the war, Sentinels could see through many types of cloaks, are equipped with advanced scanners, and are resistant to supernatural energy. For storage and fast deployment, Sentinels can fold up into semi-cubic shapes. In terms of intelligence, Sentinels appear to be rather intelligent, able to formulate strategies independently of a command unit, although they lack emotional capabilities.

Background
Sentinels were created by the Intergalactic Empire as a basic security unit, but then became a full-fledged war asset during the Trans-Galactic War and later conflicts.
