Trolls and hobgoblins are both mythical creatures often found in folklore and fantasy literature, but they have distinct characteristics and origins.

Trolls are typically described as large, ugly, and brutish creatures with supernatural strength. They are commonly portrayed as being solitary, living in remote forests or mountains, and are known for their hostility towards humans. Trolls are often depicted as having a regenerative ability, being able to heal quickly from injuries, such as severed limbs. They are also vulnerable to sunlight or fire in many stories.

On the other hand, hobgoblins are smaller and more mischievous creatures compared to trolls. They are often depicted as playful or trickster-like beings, known for causing harmless pranks or mischief rather than outright harm. Hobgoblins are sometimes described as having a more human-like appearance, with pointed ears or animal features. They are also often associated with household tasks, such as helping with chores or guarding the home.

In summary, trolls are larger, more aggressive creatures with a reputation for violence, while hobgoblins are smaller, more playful beings known for their mischievous nature.
