Pounce. If a Humanoid Monopod moves at least 20 feet straight toward a creature and then hits it with a stomp attack on the same turn, that target must succeed on a DC 11 Strength saving throw or be knocked prone. If the target is prone, a Humanoid Monopod can make one weapon attack against it as a bonus action.
Running Leap. With a 10-foot running start, a Humanoid Monopod able to move at full speed can long jump up to 15 feet.
Multiattack. A Humanoid Monopod can make two melee attacks or two ranged attacks.
Javelin. Melee or Ranged Weapon Attack: +3 to hit, reach 5 ft. or range 30/120 ft., one creature. Hit: 4 (1d6 + 1) piercing damage.
Stomp. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) bludgeoning damage.
Deflect. A Humanoid Monopod can add 3 to one saving throw that it would otherwise fail against damage-causing spells and area-of-effect attacks, such as Fireball, by interposing its tough, giant rear foot between itself and the source of the damage. To do so, the Monopod must be able to see the attack and not be surprised and it must allow for a saving throw. 
"Ctesias speaks also of another race of men, who have only one leg but are able to leap with surprising agility. The same people are also called Skiapodae, because they are in the habit of lying on their backs, during the time of the extreme heat, and protect themselves from the sun by the shade of their feet."
— Pliny the Elder
Monopod, Humanoid
Humanoid Monopods are people native to Ethiopia that have just one leg. They are sometimes referred to as Skiapodae, or "shadow feet," for their practice of laying on their backs and using their huge feet as umbrellas to protect them from rain or the sun. Such creatures will use normal human weapons and if expecting trouble may also be equipped with armor and shields, thereby improving their ACs as the GM deems appropriate. They can move very quickly, hopping along on their single legs and oversized feet, and if charging to the attack leap onto and stomp opponents. 
Encounters with Humanoid Monopods
Typically, 3d6 Humanoid Monopods will be encountered and about a third will be females. For every six such Skiapodae in a group there will be one that has 3 hit dice, for every 12 encountered there will be one with 4 hit dice, and if there are as many as 18 there will be a chief with 5-8 hit dice. If encountered in their village or lair, there will be an additional 50% as many female monopods and 50% as many children as there are males, and 1-3 of the women will have the abilities of 1st to 8th level Clerics.
