Example Beast Bondmaster 1.8 Companion: Bear

Keen Smell and Hearing. The bear has advantage on Wisdom (Perception) checks that rely on smell or hearing.

Spider Climb. The bear can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Harry. The Beast Bondmaster can use a bonus action to designate one creature within 5 ft. of the bear as the bear's Harry Target. Whenever the bear makes an opportunity attack against its Harry Target, if the attack hits, the Harry Target's speed is reduced to 0 until the end of the current turn. The bear will continue to Harry the target until the target dies, the bear is incapacitated, or the Beast Bondmaster uses another bonus action to change the bear's Harry Target.

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 1d6 + 2 slashing damage.

Rush. The Beast Bondmaster can expend one Loyalty Die and use a bonus action on the Beast Bondmaster's turn to direct the bear to make a melee weapon attack against its Harry Target. If the attack hits, it adds the Loyalty Die to the damage roll, and if the target is Large or smaller, it must make a DC 13 Strength saving throw. On a failed save, the bear pushes the target 5 ft. and moves 5 ft. toward the target. This movement does not provoke attacks of opportunity. On a successful save, the next attack against the target before the start of the Beast Bondmaster's next turn has advantage.

Grapple. The Beast Bondmaster can expend one Loyalty Die and use a bonus action on the Beast Bondmaster's turn to direct the bear to make a melee weapon attack against its Harry Target. If the attack hits, it adds the Loyalty Die to the damage roll, and the target is grappled. Until this grapple ends, the target is restrained. If the Beast Bondmaster or the bear attacks another target, the grappled target is no longer grappled.

Second Wind. The bear gains its own Second Wind. On the Beast Bondmaster's turn, the Beast Bondmaster can use a bonus action to cause the bear to use its Second Wind, regaining hit points equal to 1d8 + the Beast Bondmaster's fighter level. Once the bear uses this feature, it must finish a short or long rest before it can use it again. This is in addition to the Beast Bondmaster's Second Wind ability, and both can be used once per short rest.
