Angrath, The Flame Chained

Charge. If the minotaur moves at least 10 feet straight toward a target and then hits it with a gore attack on the same turn, the target takes an extra 9 (2d8) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be pushed up to 10 feet away and knocked prone.

Labyrinthine Recall. The minotaur can perfectly recall any path it has traveled.

Reckless. At the start of its turn, the minotaur can gain advantage on all melee weapon attack rolls it makes during that turn, but attack rolls against it have advantage until the start of its next turn.

Multiattack. Angrath makes 2 attacks; one with its longsword and one with its whip.

Whip. Melee weapon attack: [range 30ft] . +10 to hit, one target. Hit: 3d6+6 slashing damage + 4d6 fire damage. The target must succeed on a dc 18 strength save or be grappled and pulled 25 ft. closer. 

Longsword. Melee Weapon Attack: [rollable]+6;{"diceNotation":"1d20+10 to hit, reach 5 ft., one target. Hit: 17, 2d8 + 8 slashing damage + 3d8 lightning damage. 

Horns. Your horns are natural melee weapons, which you can use to make unarmed strikes. If you hit with them, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Gore. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (3d8 + 4) piercing damage.

Planeswalker

Goring Rush. Immediately after you use the Dash action on your turn and move at least 20 feet, you can make one melee attack with your horns as a bonus action.

Hammering Horns. Immediately after you hit a creature with a melee attack as a part of the Attack action on your turn, you can use a bonus action to attempt to shove that target with your horns. The target must be within 5 feet of you and no more than one size larger than you. Unless it succeeds on a Strength saving throw against a DC equal to 8 + your proficiency bonus + your Strength modifier, you push it up to 10 feet away from you.
