Here's my GR, inspired by some of the awesome customs here in FigureRealm. Wanted a gritty biker look and the NECA Terminator base was perfect. Here's the complete recipe that I used:

Head: ML Ghost Rider (Rider series) with ML Ultimate Goblin fire effect
Torso, Jacket, Upper Arms & Legs: NECA Terminator Ultimate Police Station Assault T-800
Lower Arms: ML Ghost Rider (TOybiz, Modified)
Fire chain effect: NECA Kratos
Shotgun: NECA Dante
