In VP 1.0, he's right before the drawbridge to Xygoz room. There's a guardian wurm that roams back and forth, and a static lava drake down the ramp by the lava that doesn't move. The lava drake is the PH for malicious.
Second screenshot above shows the map where I was fighting him, that's roughly where he spawned
