Mavis Drewry

Mavis Drewry is a student at the S.C.C(Sodor Community College).

She is 16 years old and has two stepbrothers named Bill and Ben Bagnall.

Her father, Rys Drewry, had married her now-stepmother, Katrina Bagnall, who is the mother of the twins Bill and Ben.

She is young and full of her own ideas.

She used to be quite mischievous.

One time, Toby Holden had to patch her up because she got her arm injured on a busy level crossing, immediately after she blamed him for making her looked foolish.

Diesel, her then boyfriend, gave the idea to hire the "Troublesome Truckers" gang.

The troublesome truckers took it too far and almost killed Toby by throwing him off an unstable bridge.

Mavis was horrified and saved Toby from his fall, and afterwards she broke down into tears over what the troublesome truckers had done, she asked Toby to forgive her, which he did because of his old-fashioned moral values.
