Northern Lights Suplex
From Luchawiki

A suplex from a waistlock position. In Mexico, it's mostly done with a bridge, though the attacker can also drop or toss the opponent. It is pretty much a belly-to-belly variation of the German Suplex. It is more common in Lucha Libre than the German Suplex because the receiver lands on their back rather than their head and neck.

Arez's Saharawi Suplex is ultimately a bridging Northern Lights, albeit with a complex set up. The opponent is first held horizontally across the aggressor's chest ala a front-powerslam position, only to instead be swung sideways into the Northern Lights starting position, without their feet touching the ground. This adds extra momentum to the subsequent impact.
