Bog is a boggi and Beaker's pet. He has brown, orange, black, and white fur and skin and yellow eyes.

While in the Monster Hunter universe, the team comes across a fighting arena created by hunters. They infiltrate the arena by putting their own rescued beasts into the fights. They all only pretend to fight each other to give the others time to rescue the trapped beasts. Beaker rescues Bog and he's grateful.

Bog is a mischievous and humorous animal. Although he cannot speak, Bog shows a lot of emotions through his facial expressions and body language. Bog has even been shown to make a raspy laughing sort of noise and often gives a few critical looks if he doesn't like the looks of something. When he sees something wrong, he's almost always the first to alert the rest of the group.

Bog likes to work together in packs in order to take down enemies. Bog is known to use his speed to wear down potential prey. He uses his claws in battle, so he must be wary of them. Bog is a cunning and calculating monster that patiently waits for openings to strike. However, he will flee when there is significant danger.

Trivia:

Bog gets his name from being a abyssal lagiacrus.

He's the first bird wyvern from the battle arena to be introduced.
