Emela-Ntouka (5e Creature)
From D&D Wiki
Huge beast, unaligned
Aggressive. As a bonus action, the emela-ntouka can move up to its speed toward a hostile creature that it can see.
Rampage. When the emela-ntouka reduces a creature to 0 hit points with a melee attack on its turn, the emela-ntouka can take a bonus action to move up to half its speed and make a bite attack.
Trampling Charge. If the emela-ntouka moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, the target takes an extra 14 (4d6) piercing damage. If the target is a creature, it must succeed on a DC 15 Strength saving throw or be knocked prone. If the target is prone, the emela-ntouka can make one stomp attack against it as a bonus action.
Multiattack. The emela-ntouka makes two melee attacks.
Gore. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 25 (3d12 + 6) piercing damage.

Unbridled Fury. In response to being hit by a melee attack, the emela-ntouka can make one melee weapon attack with advantage against the attacker.
Emela-ntouka is the name given to a large, rhinocerine mammal known to inhabit warm, tropical rain forests. Growing to the size of an elephant with a single, long horn atop its head, these beasts are respected by native peoples and are not to be trifled with by just any adventuring party.
Lakeside Lumberer. While not an innately aquatic creature, emela-ntouka are found most commonly not far from the water's edge. They are known to feed on the succulent water plants beneath the surface and wallow in the mud. They guard this territory with feverish aggression but otherwise tend to leave most people alone.
Pachyderm Aversion. The name "Emela-Ntouka" means "Elephant Killer" and the creature lives up to this reputation. For whatever reason, emela-ntouka have a primal hatred of elephants and actively hunt down any nearby. The territory of an emela-ntouka is marked by the gored corpses of elephants littered throughout the jungle.
