As a new day dawns in Arcadia, two trolls are locked in an epic battle with major consequences for the human world -- and one human boy in particular.

Still reeling from the discovery of the amulet's power, a stunned Jim meets his new mentors and learns he's been tasked with a sacred responsibility.

Jim and Toby tour Heartstone Trollmarket, where Jim begins his training and the presence of the first human Trollhunter stirs up bitter resentment.

Jim preps for a high-stakes rematch against Draal, the amulet's seemingly rightful heir. But their animosity gives way to a surprising partnership.

While Draal settles into his new digs, Jim volunteers to babysit so he can find out whether Claire's little brother, Enrique, is a Changeling.

As Claire grows increasingly suspicious, Jim's mom invites Strickler over for dinner, where the tension is so thick, you could cut it with a knife.

Two fateful battles unfold when Bular and Strickler order Jim to unlock the portal and free Gunmar and his Gumm-Gumm Army from the Darklands.

Jim searches for a way to kill Gunmar so Claire can bring her brother back home. A power-hungry Strickler returns to Arcadia with Angor Rot.

The heroes' search for the second Triumbric Stone takes them deep into unfamiliar marshlands. Claire asks Jim to be her dance partner.

The Changeling posing as Claire's little brother throws a house party for the trolls of Arcadia. Jim and Toby look for a way to take Strickler's ring.

A reluctant Jim joins forces with Strickler to keep Barbara alive. Gnome Chompsky returns from the Darklands with important news about Enrique.
