Mr. Herrera is the Spanish teacher at Highland High. Not much is known but he makes prominent appearances in No Laughing and The Great Cornholio, both of them having Beavis and Butt-head harassing him. He has gray hair & brown skin, although later on, his looks changed in The Great Cornholio & Beavis and Butt-head Are Dead. He also makes a cameo in "Walking Erect."
In Dumb Design, he made his official return as a background character and had gray hair, and appeared again in Copy Machine as a background character while a crowd were watching the people attempt to rescue Beavis from smashing his butt into the machine. Mr. Herrera now has brown hair and looks much younger than he did in his earlier appearance. He may also teach English now as he reminds Beavis and Butt-head to use "I before E except after C" in School Test. He is voiced by Sam Johnson.
