Boar the Wolf

Pack Tactics. The wolf has Advantage on attack rolls against a creature if at least one of the wolf’s allies is within 5 feet of the creature and the ally doesn’t have the Incapacitated condition.

Bite.  Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (3d4 + 3) piercing damage. If the target is a creature, it must succeed on a DC 12 Strength saving throw or be knocked prone.

Throw.

you hit a medium or smaller creature with a bite attack, you can throw it up to 10 ft to your main companion.

Growl (1/Short Rest)

Boar releases a deep, menacing growl, amplified by the fearsome sight of his partially burned face. One creature of Boar’s choice within 30 feet that can see and hear him must succeed on a DC 13 Wisdom saving throw or become frightened until the end of its next turn.

A creature frightened in this way can repeat the saving throw at the end of each of its turns, ending the effect on a success.
A creature that succeeds on the initial save becomes immune to Boar’s Growl for 24 hours.

When within 5ft of an attacking enemy (attacking you or one of your allies), you can use your reaction to try and stop that attack. Roll a d4 and subtract that from the enemies roll.

When your companion starts a rage within 10 ft of you, you can rage with them for 1d4 rounds.
