Bartholomew Oobleck

Bartholomew Oobleck is a teacher at Beacon Academy. He is first seen in Jaunedice, Pt.2 teaching history to the students, specifically teaching about the war between the Humans and the Faunus, which appears to have taken place a few generations before the start of the series.

Appearance
Bartholomew appears to be a rather young man, with messy green hair and brown eyes. His attire is disheveled: his white shirt partially tucked into his dark-green pants and its collar raised, showing a slack yellow tie, along with mismatched brown and black shoes. He also has round glasses that appear to be opaque.

When assigned to lead Team RWBY on a Search and Destroy mission located in southeast Vale during the events of Field Trip, Oobleck wore a long khaki greatcoat, off-gray waistcoat and a pith helmet; this is presumably his combat outfit. All of which appear to be properly worn and tucked in and such, unlike his earlier attire. He also carried a large backpack.

Personality
Bartholomew's trademark characteristics are his extreme hyperactivity and his love for coffee. Not only does Bartholomew frequently 'glide' about in class at incredible speeds, he also speaks at a very fast pace or almost 'cluttering'. When moving, he often appears as a blur or moves so quickly that his legs appear stationary.

This energy might be a result of him constantly drinking what appears to be coffee. His mug is similar to that of Ozpin. His unkempt look and the mess on and around his desk suggests that he has little to no regard for tidiness.

During his class, Bartholomew is shown to be very enthusiastic and strict about his work, being very happy when inattentive students, such as Jaune Arc, seem ready to contribute to class and punishing poorly performing students.

Bartholomew views history as an important way to prevent the repetition of past mistakes. He also highly respects Faunus, shown when his head shook disapprovingly at Cardin Winchester's discriminatory remark.

Bartholemew displays a great deal of enthusiasm for all of his work, including his duties as a Huntsman. He also clearly relishes his role as a mentor and instructor.

Abilities and Powers
Bartholemew's fast movements are repeated on several occasions, making it clear that these are real powers, likely his Semblance.

Despite his eccentric demeanor and his civilian appearance, he is a skilled and experienced Huntsman, considered qualifiied to escort students on field assignments and assess their fighting abilities.
