Fictional character biography
Peter Bishop was born in 1978, in the alternate universe, to parents Walter Bishop, also known as "Walternate", and his wife Elizabeth Bishop. In 1985, Peter acquired an extremely rare and savage genetic disease. His father, a brilliant scientist (in both universes), worked around-the-clock to save him.
Revealed in the episode "Peter", the Walter Bishop of the prime-universe watched his own son, the prime-universe version of Peter, die because of the same disease. He would frequently watch the other Peter living in the alternate universe via a "trans-dimensional window", which could allow someone to view the Other Side. Eventually, Walter formulated a compound and opened a doorway into the other universe, with the intentions of saving the other Peter from death. However, the vial containing the compound shattered on his way over to the Other Side, so he was forced to kidnap Peter, bring him over to the prime-universe, cure him, and then return him. But, after curing Peter on our side, he and his wife could not find themselves able to return him, so they raised him as their own.
