Abstract: We present 3D core-collapse supernova simulations of massive Pop-III progenitor stars at the transition to the pulsational pair instability regime. We simulate two progenitor models with initial masses of 85 M⊙ and 100 M⊙ with the LS220, SFHo, and SFHx equations of state. The 85 M⊙ progenitor experiences a pair instability pulse coincident with core collapse, whereas the 100 M⊙ progenitor has already gone through a sequence of four pulses 1,500 years before collapse in which it ejected its H and He envelope.
