This opponent will make meat disgusting for you. The following page of the guide to Steelrising provides a description and how to defeat the mini-boss Unstable Butcher.
Unstable Butcher uses moves you may have seen when fighting the Ice Squires. You can read more about them on a separate page about the Cooks.
So you can expect sweeping cleaver attacks. In addition, it can spin and deal damage to enemies around it over a small area. Its strongest attack, however, are the sparks. They cause both burn and paralysis effect and deplete a lot of health. It is best to jump away from them or run behind the Automat's back. In addition, it has the ability to charge at you (although it is not very fast).
Due to its slowness, it's best to attack this Automat by leaping towards it and then moving away, but staying relatively close to the enemy. Run up from the back, deal a few attacks and jump away.
A very effective tactic in this case is to freeze the enemy. This will allow you to attack it with any problems.
