Stumped on this synth (not skrillex XD)

[Cyprus]

Shun me for it but i have a synth Question.
I just love this synth and whever I try and make it I cant seem to get a pleasing result.
Its the first synth in the drop of this

I'm guessing you use massive and some sort of oscillator on formant? But I cant seem to get it. If someone could just explain it broadly, I dont need it spot perfect just the tone you know?

So if anyone can help me I'd be forever greatful!
Thanks in advance.
