i think this is a saw wave which has been heavily distorted and filtered.
i dont use FL studio so im not sure how you would go about it...
From what i remember there is a saw plugin on FL called 3xosc (could be wrong)

Edit: its most likely using more than one oscillator...

also the thing making it sound beefy is the sine wave layered under it..
