Biography
Proteus was a very young engine from the hills of Sodor with a magical lamp, and the legend goes that if any engine ever found it, their wishes would come true. The clues to finding the magic lamp are feeling a rush of wind when the lamp is near, hearing a noisy creaking sound, and see a flickering light that shines on and off.

It had been likely he used to work on the Mid Sodor Railway(which later became Smudger's Railway)where he worked with the other engines. In the year 2015,he and Bertram were possessed by Smudger to look for Duke.￼
