Mr T

"Mr T" was a man who wore an overabundance of gold jewellery, which made him a deadly enemy to the Cybermen. (NOTVALID: Doctor What 3)

In an alternate account of the events of Christmas 1851, Jackson Lake picked up a different infostamp that made him think he was Mr T instead of the Doctor. (NOTVALID: Doctor Whoah! 405)

Behind the scenes
Mr T is perhaps best known for portraying B.A. Baracus on, a character who appeared in LEGO Dimensions and New Adventures Await!
