Azcatra

Keen Smell. The azcatra has advantage on Wisdom (Perception) checks that rely on smell.

Pounce. If the azcatra moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the tiger can make one bite attack against it as a bonus action.

Season Shift. As an action, the azcatra can shift her seasonal coat to a specific form. If it is not what the default coat is, based off the current environment the azcatra is in, the shifted form lasts for 1 minute. The azcatra can repeat this twice per long rest. 

Seasonal Coats. Depending on the environment that an azcatra is in, it changes it's coat to match the environmental conditions around it. An azcatra shifts its coat to match spring, summer, fall, and winter environmental conditions.

Spring. The coat of the azcatra starts to bloom with flowers buds and moss over it, the mane of the coat turning a soft green color, like fresh grass growing. The claws of the azcatra turn a green shade. A spring azcatra gains the tremorsense ability and applies an additional 1d4 poison damage to each claw attack. 

Summer.  The flower buds on the coat of the azcatra bloom, with variations in petal color from reds and yellows. The mane starts to change and become more light green. Additionally, the claws of the azcatra turn a deep reddish shade. A summer azcatra increases its speed by 20ft and applies an additional 1d4 fire damage to each claw attack.

Fall. The coat of the azcatra changes, with the flower buds and moss starting to deepen in shade to hues of brown and orange. The claws of the azcatra turn a purple shade. The mane of the azcatra changes, with the light green color shifting instead to a reddish hue and starts to become more thick, with additions of fur around the paws, as if preparing for a long cold. A fall azcatra has darkvision (60ft) and applies an additional 1d4 necrotic damage to each claw attack. 

Winter. The coat of the azcatra changes, with the flowers and moss falling off. The mane changes to a soft blue color and fur continues to grow and become even thicker, now additionally covering the underside of the azcatra, which seems to harden as if becoming an additional defense. The claws of a winter azcatra turn a icy blue color. A winter azcatra gains an additional +2 bonus to natural AC and applies an additional 1d4 cold damage to each claw attack. 

Enlarge/Reduce. An azcatra can, as a spell-like ability, cast Enlarge/Reduce on itself. It can use this ability twice per day. 

Multiattack. An azcatra makes three attaks, one with its bite and two with its claws. 

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d10 + 3) piercing damage.

Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (2d8 + 3) slashing damage.
