Data (Assimilation²)

Data was an Android who served aboard the USS Enterprise D in the 24th century. Data was present on the ship's Holodeck with William Riker and Becerly Crusher when The Doctor's TARDIS landed in it's "Dixon Hill" holonovel. The Doctor noted that the sight of an android wearing a pinstripe suit in 1941 San Francisco was unusual. (IDW: Assimilation²)
