Slicer

Slicers are advanced combat units utilized by Null Sector with a plasma cutter for a head. Although less common than Nulltroopers, they make a up a fairly large portion of enemy forces in Overwatch Uprising.

Summary
Slicers are frequently encountered in Uprising, and are easier to kill than Nulltroopers or Eradicators. They appear as small, bipedal robots with a design similar to "raptors".

Tactics
While Slicers typically will always attack the Payload with their head-cannons, they can be easily killed by Reinhardt's hammer swings. Unless you let them bunch up, this tiny enemy truly is no problem to deal with.

Trivia

 * Slicers do not speak or make any sort of communication attempt.
