What Junkrat sees is a saboteur, gun raised, ready to take a shot at the person dismantling all their hard work.

What Junkrat sees next is a metal trident flying in of its own volition, knocking the saboteur's knees out from under them and clocking them in the head as they go down. The saboteur collapses in a heap, and the trident hovers; after a moment, the trident transforms into Sawtooth, looking a little harried but none the worse for the wear. "There's more on the way," he says, already turning to keep an eye on the area. "I'll watch your back."
