Apteros (5e Creature)
From D&D Wiki
Medium monstrosity, unaligned
Run Down. If the apteros moves at least 20 feet towards a target and then hits it with a claw attack on the same turn, the apteros can make one bite attack against it without using an action.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 16 (3d8 + 3) piercing damage.
Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage. If the target is a Small or smaller creature, it is grappled (escape DC 13). The apteros has two claws, each of which can grapple only one creature.
Rampage. When the apteros reduces a creature to 0 hit points with a melee attack on its turn, the apteros can move up to half its speed and make a claw attack.
These creatures are the result of the unnatural fusion between a humanoid and a dragonfly. A voracious predator with keen senses, the apteros is constantly in search of its next meal as it darts from place to place, its massive, highly sensitive eyes easily detecting the slightest twitch of a camouflaged toad even as it dashes through a fog-shrouded marsh; it has lost its capacity for flight, but boasts one of the fastest running speeds of any land animal. It typically skewers and devours smaller prey on the run, while pouncing larger beasts from behind and attempting to gnaw through their neck. An apteros is adept not only as hunting and killing, but at searching, watching and gathering information, its large brain capable of processing detailed visual input even as it dashes through its territory at top speed. Apteros mate tail-to-tail for hours at a time, and will continue running and hunting while so attached. Young are miniature versions of adults, and born immediately capable of fending for themselves.
