Old Gears. The Flawed one being made of scrap from old bots is falling apart, the excessive energy it uses while fighting make its overcoming hunger to strong, the gears start to break as the movement of the creature wears on them. The flawed One while in combat will take 1d6 force damage each turn they don't devour a corpse.

Smack. Melee Weapon Attack: +2 to hit, reach 5 feet, 1 target. Hit: (1d6 + Strength Modifier) [Bludgeoning] damage.

Spark Burst. Ranged Weapon Attack: range 5/25 feet in a cone shape. the opponent must roll a dexterity 14 DC  or take (1d4 + 2) [Fire] damage. Then the flawed one takes 2 [Fire] damage

Devour. The flawed One can spend a bonus action to remove a corpse within 5 feet of itself and heal 1d6 health per level of the creature the corpse was of, this health gain can bring them above there max life. The DM will next roll a d20 and if the result is 12 or higher the DM can choose an attack, speed (fly speed included), ability, special trait, or reaction the creature had access to and the Flawed One will gain that attribute.
