The male certainly has a razorback look to him.
The tusks would be my biggest concern with him. Even if he was just being friendly he could really make a mess of a @little-pepper.
But given his displayed aggression, even if he is a pot bellied pig, he is going to cause problems for your other pigs.
I sense a video on how to make your own home cured bacon coming on from @papa-pepper :-)
We will at least be having a pig roast it looks like.
