A Brute, the villain equivalent of a "tank" or "brick" as well as the exact opposite of a weakling, is basically a character who is physically strong and/or possesses superhuman strength, often coupled with durability; much stronger than a typical thug or fighter, but often not as bright.

Alternatively, a brute is also a villain who usually has a huge force, thanks to aspects in their minds, like a poor impulse control, rage, mental illness/insanity, among others. Examples are Jack Torrance, the Joker from The Dark Knight, Edwin Epps, the Earl of Lemongrab, etc.
