A [[bald eagle]] accompanying [[Essex (warship girls r)|USS Essex]] in [[Warship Girls R]]. He does most of the talking since Essex is essentially a silent character, having very few spoken lines in-game.

Bell is grumpy and has a rather short temper, often resulting in him yelling commentary here and there.
He is a full-size, realistic bald eagle most of the time, but will turn into an egg-shaped chibi when Essex is critically damaged. 

Quite probably a reference to the bald eagle on the ship's emblem of USS Essex. 

The name "Bell McCamp" is wordplay referring to real-life pilot "David McCampbell":https://en.wikipedia.org/wiki/David_McCampbell, the Essex Ace pilot who shot down 34 Japanese planes during his service.
