Glynda Goodwitch

Glynda Goodwitch is a character in the world of RWBY and a staff member at Beacon Academy. She first appeared in the Pilot episode, saving Ruby from an attack by an as of yet unknown enemy and is the first known "Huntress" in the series.

Abilities & Powers
Glynda is seen using a weapon that is either a riding crop or possibly some kind of wand in her fight against Crimson. This weapon can generate a wide variety of techniques through the use of Dust, including weather manipulation and object manipulation. It also is shown being used to create an energy shield to protect Ruby from the explosion of a Dust crystal.

Stylistically, some of Glynda's combat abilities strongly resemble those of Weiss Schnee. It is possible that both are followers of a particular style or tradition of Dust usage.

Trivia

 * Her name may be a reference to Glinda the Good Witch of the South from "The Wizard of Oz".
