The Bogeyman

The Bogeyman is a frightening monster invoked by parents world wide to frighten their misbehaving children. He is usually depicted as a beast or ogre of some kind, although the visage of a psychotic old man is also not uncommon. One feature found in the legends of many countries is the large sack he carries, which to kidnap naughty children and take them away.

Bruckee

In Irish folklore the Bruckee is a huge carnivorous badger-like creature, the size of a large bear. It is known for living in or near large bodies of water and devouring entire herds of cattle.

Pukwudgie

In Wampanog folklore, a Pukwudgie is a short, trollish like nature spirit, with large ears, nose, and hands, and smooth skin. They are said to have several different magic powers, such as the ability to disappear, transform into animals, or instantly create fire. If one crosses a Pukwudgie it's best to leave them alone, else they might follow you home and play cruel tricks.

Water Leaper

The Llamhigyn Y Dwr, or "Water Leaper" is a monster from Welsh myth. It takes the form of a large, legless amphibian with bat-like wings and a long, barbed tail. The creature is blamed for broken fishing lines, missing livestock, and has even been known to attack humans.

Black Shuck

Hideous demon dogs from English folklore. They are usually described as oversized dogs (in some instances, as large as a horse) with glowing red or green eyes. Their step is supposed to scorch the ground. It is rare for the devil dog to actually harm anyone, but those who witness the beast will shortly come to an untimely end.

Bunyip

A Bunyip is a large ogre-like figure from Australian aboriginal folklore. Bunyips make their homes in waterholes, bogs, or swamps, and prey upon those who get too close. There seems to be no clear description of the creature, with come accounts describing a sleek, panther-like water cat, while others add any number of claws, fangs, ears, horns, beaks, or bills. It usually kills it's prey by hugging and crushing them to death.

Ogre

Tales of Ogres can be found in all cultures. They are generally depicted as overly large, strong, and ugly human beings, usually cannibalistic, and sometimes with features of various animals (horns, pig noses, fangs, etc.) They are also usually not so smart, and most often than not are outwitted rather than defeated in open combat. Despite their intelligence handicap they also posses a deeper understanding of various magics and curses, especially the female Ogress. They share a lot in common with Giants and Trolls.

I picture them as larger, more brutal human beings, perhaps an evolutionary offshoot of Neanderthals.

Oni

The Oni is the equivalent of a demon, troll, or orge in Japanese folklore. Like their western counterparts they're usually depicted as large, hideous, and not too bright. However Japanese orges are schooled in the magical arts to a larger degree, often possessing the ability to turn invisible, transform into animals, fly, etc. They are commonly depicted in a red or bule color, with wild hair, fangs, claws, and carrying an iron club ( kanabō. )
