I recently posted somewhere (i think in gamefaqs) about how sometimes I name the Epoch the RX-XR...This name comes from within Trigger, but it comes from two sources...1) A kid in Porre talks about (or his grandpa talks about him talking about it) wanting to pilot the RX-XR and 2) RX-XR is the name of the robot which keeps your best scores when racing Jhonny in the future.
Is this just a weird coincidence? Is there some deeper meaning behind the weird serial number? Is there perhaps some real-world parallel? This hasn't already been gone over, right?
