About Wren...

i am convinced that wren is the same cyborg, in both ps3 and ps4.
wren could easily be able to travel back to algo and build zelan, in theory, aww come on, hes a smart bot, it wouldnt be hard to make a teleportation device.

As for me, I'm convinced you like saying nonsenses, especially when you have been explained it was impossible at least 2 times. Do you only read answers to your threads ?

Well highly theoretical, if we take the time travel ending for canon there might be a slight possibility he came to Algo with the Earthmen. But that would have to mean his bio is wrong as it states he was created 996 years before PSIV and the Earthmen had been around much longer. Maybe he was moved to Motavia and got derelict and by "building" they merely meant reactivating. But I find it highly improbable.

And with a little more "if", my aunt would be my uncle

I'm sure that will be possible at some point in the future.

So am I. But you need more "if"

This wouldn't really make any logical sence in either of the timelines.

Sure they are both wren-type cyborgs. They are not the same character though.
