Mighty Mac

Mighty and Mac are a double-ended Fairlie duplex locomotive, and conjoined twins.

Biography
They first appeared in the official Thomas & Friends series in 2005 during Series 9, and made their last appearance in Series 12 in 2008. At some point after 2008, Mighty Mac had to get a check-up because they were growing ill and weak. Once they got their check-up they realized that they had cancer due to all of the crack and drugs they had been taking. Mighty had it worse than Mac on the other hand. Mac had about 3 months to live while Mighty had 3 weeks to live. The reason for this is because Mighty had been taking drugs more often than Mac, plus it turned out that the hair on his forehead was actually a tumor, making his health even worse. Mighty died in his sleep 3 weeks later at the Wharf. Mr. Percival soon realized that having a half-alive-conjoined twin engine could cause him some great deal of trouble with the Mayor of Sodor. And since he knew that Mac wouldn't survive for that much longer he decided to just scrap Mighty Mac all together to get them off his hands. Although Mighty Mac has not appeared in any of the SC Shorts as of yet, he was mentioned to be dead by Thomas in "The Return Of The Loathed Locos."
