The new Alien Canon operates without recognition of AVP.
Lance Henriksen is two different characters, in two different licenses.
AVP 2010 solidifies Michael Bishop as synthetic IMO-
Charles Bishop Weyland's consciousness within synthetic after synthetic,
each with a new name, Charles, Michael, Karl.
(Predator Series, AVP, AVPR, Alien, Aliens A3, AVP 2010)
Within this AVP canon, they're undoubtedly related because they're in essence the same person.
BUT...
Within the new Alien Canon which includes Prometheus and The Weyland-Yutani Report, Michael Bishop is human.
Unrelated to Peter Weyland, following in his footsteps.
(Charles Bishop Weyland, Karl Bishop Weyland- who?)
