Synthetic Body. CU 724 is an artificial organism designed for combat. He has resistance to non-magical damage, increased AC, and doesn't need to eat, breath, or sleep. Additionally, his body can't be modified against his will or put to sleep with magic.

Threat Analysis. CU 724 is adept at analyzing people's micro expressions, body language, and capabilities to determine their overall hostility and threat. He has advantage when rolling insight checks to determine hostility.

Auto-repair Matrix. Each round, CU 724 recovers 12 HP and will automatically stabilize and recover when downed. Additionally, if he has lost any limbs, they can be rebuilt over the course of a short rest.

Multiattack. CU 724 can make 2 melee or ranged attacks each turn.

Gauss Cannon. ranged weapon attack: +8 to hit, reach 120 ft., one target, Hit: 33 (6d8 +7) force damage.

Kinetic Strike. melee weapon attack: +8 to hit, reach 10ft., one target, Hit: 18 (2d10 + 8) bludgeoning damage. This counts as magical for the purpose of overcoming resistances.

Hard-Light Shielding. CU 724 creates a thin barrier of hard light around himself. It has a 27 AC, resistance to magic damage, and 25 HP. If the barrier persists at the start of CU 724's turn, it regains all missing hit points. 

Delayed Explosive. CU 724 can deploy an explosive to detonate at any instant he chooses (even part way through a character's movement action). It can be thrown up to 45ft. or deployed right beside him quietly. He can roll sleight of hand to conceal this action if it is deployed within 5 ft. of him. Only one explosive can be deployed at a time. When detonated, targets within 10ft. take 22 (3d12 + 4) fire damage.

Hard-Light Barrier. When an enemy makes a ranged attack against CU 724, He can respond by creating a body-sized barrier with 25 HP. The barrier counts as full cover but doesn't break line of sight.

Return Fire. If an enemy misses a ranged attack against CU 724, he can spend his reaction to immediately attempt to hit them with his gauss cannon.
