Turning Mecard stars Jason, a grade-schooler who meets a Mechanical, a transforming minicar from the alternate world of Triforce, named Evan. Jason and Evan are both searching for missing family members, and team up to help each other. Together, they meet more Mecanimals as they battle across dimensions and learn important lessons along the way.

The team investigate Jason's house for clues about Mr K's whereabouts. In their search, they come across a strange human toy car that looks exactly the same as Evan.

The crew suspect foul play from Black Mirror in Mr K's disappearance and return to Triforce when Dr Franklin says he is being pressured to make Mecanimals.

Jason and his crew are promptly captured by the king's soldiers when they return to the Red Hall. They must escape before it's too late.

Jason and his friends set off to see Isobel at the castle, but they must first outwit the soldiers at the border to be able to cross into Blue Land.

Jason and his friends encounter some hostile animals on their way to Dr Franklin's secret lab. There, they attempt to understand why the animals seem to hate Mecanimals.

Geryon's evil influence takes hold of Dana, causing her to forget who she is. After learning that he was under the same spell, Dabi vows to snap his sister out of it before it's too late.

No longer under a spell, Dana and Dabi are realised to be useful to Jason and Isobel who seek information regarding Lord Eltopo and Mr K.

Sphinx reveals he was created by Eltopo. Unaware that Jason is listening, Dr Franklin shares his suspicions with Isobel that Eltopo is Mr K.

In order to stay off Mecanimal Mantari's radar, Jason and his friends head through the valley; back at Black Mirror's hide-out, Sphinx's escape leads to Eltopo's imprisonment.

While Brandon, Juliette and Kevin play games, Brandon wonders if it is raining in Jason's world. This reminds Juliette that Jason left a letter inside a book she lent to him.

With Black Mirror's hideout finally located, Jason, Isobel, Ryan and Team Goblin devise a plan to get to Dark Island.

Isobel, Ryan, Jason, Dabi and Dana travel to Dark Island to gain access to Black Mirror's secret hideout. They later must battle in order to retrieve their mecanimals, Crocky, Octa and Wingtok.

Vandyne calls out for a battle, pitting his jumbo Mecanimal Ex against Isobel, Ryan and Dabi. Vandyne gets the better of the three Mecanimals used by Isobel, Ryan and Dabi.

Black Mirror's highest officer, Jealousia, suddenly appears in an attempt to regain control over Vandyne. Unfortunately, Vandyne's disbelief in who she is does not go down well.

It's now been 8 days since Jason told Juliette and his friends he'd find his father and return to their world. Now that he's found Mr. K they could both go home but Mr. K feels responsible for what Black Mirror is doing.

Jason, Mr K, Ryan and Isobel go on the hunt for the remaining two jumbo Mecanimals. Meanwhile, Ryan doesn't know why Jason is still in Tri Force as he's found his father.

On Jason's final day in Tri Force, Ryan goes out to search for the last jumbo Mecanimal Yota, and Isobel tries to send Jason back home but Black Mirror blocks the dimension transport machine.

Jason, Mr K, and Isobel travel through the teleport path to go back to Earth. Jason's mum is shocked to see them.

Team Goblin and Ryan head to the teleport path on Dark Island. Vandyne wants Jason to go back to Tri Force so that he can defeat him in battle.

Ryan and Isobel are ecstatic when Jason comes back to Tri Force. They plan on taking Jason on a tour of Blue Land and Red Hall.

Ryan and Jason want to enter Black Mirror's hide-out to get Isobel away from Jealousia's control. Dr Franklin calms them down and persuades them to think of a better plan.

Jealousia is brainwashing Mecanimals. Vandyne relays this information to Black Mirror, but Gryphon warns him that it could be dangerous if Jealousia finds out.

Ryan and Isobel head to their homelands; Franklin advises Jason to leave Dark Island; Vandyne has escaped from Black Mirror; Vandyne only cares about finally beating Jason in a battle.

Jealousia tries her best to persuade Jason to join her on the dark side, but Jason refuses to buckle.

When Vandyne comes back to Tri Force, Gryphon and Sphinx combine to make Gryphinx. With their powers working together, Jason and Vandyne might have a chance to win the battle.

The combined power of the 30 Mechanimals finally wakes up the ultimate Mechanimal, Megadragon. The Mechanimals have lost all of their energy and are unable to move, and Black Mirror orders Gryphinx to dispose of him. That's when Mega Dragon radiates with dazzling light...
