Mighty and Mac, collectively known as Mighty Mac are a blue double-ended Fairlie duplex engine and conjoined twins. Mighty is the "older" of the two and is distinguished by a small flick of hair. Mac is the "younger" half and is distinguished by his youthful features, round nose, and freckled cheeks.
Despite the opposing personalities of the two ends, they are technically one engine.
