Weyland-Yutani has had several different origins in various media. The canonical origin was established in Prometheus. Weyland Corp was established by Peter Weyland on October 11, 2012. Sometime after Project Prometheus, Weyland Industries/Weyland Corp would acquire the Yutani Corporation thus forming the Weyland-Yutani Corporation.

Ms. Yutani was the CEO of the Japanese Yutani Corporation during the early twenty-first century. She came into posession of a Predator's plasma caster, which Yutani Corp further used to advance earth tech. Her company would later merge with Weyland Industries to form the Weyland-Yutani Corp.

现在能查到的资料也挺矛盾的
Yutani是在AVP中登场的，现在的资料也围绕着AVP中的剧情进行介绍。但是在Aliens拍摄的时候肯定没有这么设定。
