Separated at birth... Episode III

Do you remember Jackson's Warrior model? Yes, it's the one which ignited a character clash of sorts with Ibanez's Xiphos. But we learnt that both guitars was inspired by a certain BC Rich model. But Jackson's discontinued Demon (pic above)...

...& Ibanez's 540P (also discontinued) looked very similar, yes? So maybe the Xiphos episode wasn't the first design bout between the manufacturers.
