sets upon

Turns on aggressively

Sets upon means to attack suddenly and vigorously.

The phrase typically describes physical assault by one or more attackers: The gang set upon him in the alley.

It can extend to verbal attacks or aggressive criticism: Critics set upon the proposal immediately.

The construction is somewhat literary; *attacks* or *jumps* serves in casual speech.
