Hobgoblins are a sub-category of goblins whose aspects have changed drastically since the word first came into play in old English folklore. The name was first used as an abbreviation for Robin Goodfellow, the mischievous but non-threatening goblin that would later be identified as Puck. However, it soon became used to describe a friendly, amusing or good natured type of goblin.
In later English, the hobgoblin's aspects were reversed and it became identified with far more malevolent creatures, such as the bugbear or bugaboo, leading it to be seen as a source of fear or displeasure. This more modern version of a hobgoblin's nature is further strengthened by fantasy works such as J.R.R. Tolkien's The Lord of the Rings.
"Origin: England. Unusual goblins who are friendly to humans. They play fewer pranks compared to goblins, and have cheerful personalities. Robin Goodfellow and Puck from Shakespeare's plays are famous hobgoblins."
