This over-sized piranha bursts from the water, spreading broad fins as it takes to the air to sate its hunger.
Onwu Azu CR 1
When an onwu azu hits with a bite attack, it automatically grapples its foe, though the target isn’t considered to be grappling the onwu azu. Each round the onwu azu is grappling its foe, it automatically deals its bite damage.
An onwu azu can launch itself into the air and glide for up to 1 minute (depending on water and weather conditions, at the GM’s discretion). When gliding, it has a fly speed of 60 feet with clumsy maneuverability and gains Flyby Attack.
An onwu azu can notice creatures by scent within a 180-foot radius underwater and can detect blood in the water at ranges of up to 1 mile.
Environment warm oceans or rivers
Organization solitary, school (4–11), or shoal (13–33)
Onwu azus are a species of saltwater flying fish that grow to a hefty size and have a taste for the blood of warm-blooded animals. They’re similar to giant flying piranha, and their name roughly translates to “flying death”.
Like salmon, onwu azus are born in rivers and migrate downstream to the ocean during their adolescence.
There, they grow to their adult size and develop the ability to swim at incredible speeds and use their wing-like pectoral fins to glide above the waves. Onwu azus return to the river where they were born to reproduce, and die shortly afterward.
Onwu azus use their glide ability to hunt prey, and although they are capable of subsisting on smaller fish and other marine animals, they prefer the blood and meat of land-dwelling creatures. After spotting a target, schools of onwu azus soar over the waves at great speeds, hurling themselves at their preferred food sources and biting with their incredibly sharp teeth, employing a suction grip that is difficult to break. Once attached, the onwu azus continue biting until their prey is killed.
Their bites cause continuous bleeding, and most of their victims die from shock and blood loss long before the onwu azus reach vital organs. These fish can survive for up to 5 minutes out of the water, and if they succeed at killing their prey on land, they briefly feed before flopping back into the water to look for their next meal.
More than one pirate has been knocked from his ship by a surprise onwu azu attack. Rather than just leaping to take a bite of air-breathing prey, the fish will often bull rush prey on either a coast or ship’s deck, intending to knock it into the waiting mouths of the school below. Shallow inlets and river mouths in the paths of spawning onwu azus are often littered with the remains sailors and explorers who ran afoul of these deadly fish. Adventurers who find treasure in such areas would do well to wonder what killed any corpses lying beside loot and take appropriate precautions.
Onwu azus grow to over 4 feet in length with fin-spans of over 6 feet, and can weigh close to 90 pounds. Their skin is generally dark blue or brown, and their pectoral fins are a scintillating red that shimmers in the sun with a kaleidoscope of colors.
