Zen-Aku returns to rejoin with Merrick, and only by learning to accept help from his friends does Merrick defeat this evil from his past.
One night in the woods of Turtle Cove, three laser-like lights emerge from the darkness and the three broken fragments of the Zen-Aku wolf mask reform, resurrecting the fallen Duke Org, this time as a independent being.
The next day at Willie's Roadhouse, Merrick recalls performing his Lunar Break move during battle and practices the technique once more using Willie's pool table and balls. Willie approaches him and states that he practices the same exact move day after day, and wonders how he never grows tired of it. He then takes the cue and teaches Merrick a new move that increases the cue ball's power and sends it vertically airborne. Merrick catches it, surprised and impressed with his skill, and Willie sets up a game and wants Merrick to break but before it can begin, the wind blows and Merrick is alerted to the danger outside and rushes off.
Merrick runs to where he sensed the danger coming from and to his horror, begins to hear music from the flute belonging to none other than his old enemy, Zen-Aku. Merrick is in total shock as he watches his old foe, somehow resurrected, approach him as he finishes playing his flute. After some uneasy greetings, Zen-Aku sends a blast from his Crescent Blade and Merrick morphes and dodges it. A brutal battle then begins between the two old acquaintances.
As the Rangers are taking it easy in the park, they are suddenly alerted by Princess Shayla, who tells them that Merrick is in trouble and they rush out to help him.
Zen-Aku and Merrick continue to battle and Zen-Aku unfortunately has the upper hand. When the Ranger asked if he is surprised to see him, Merrick wonders how it is even possible that he has returned, as the curse had been broken. The other Rangers show up and are just as surprised as Merrick by Zen-Aku's unexplained return, as they had thought that Merrick WAS Zen-Aku, that they were one being. Watching him still struggle, Cole says that they need to help him, but just before they can morph, Merrick yells for them to not interfere, thinking that it's his fight and his alone.
Merrick is struck again by Zen-Aku and is pinned down by him. Holding him under the Crescent Blade, Zen-Aku asks Merrick if he really thought that he could escape from him after 3,000 years of being merged. Merrick argues that the mask was broken, but Zen-Aku explains that when Merrick had been freed from the curse, Zen-Aku had been as well and was now a free being, no longer depending on another to exist. Merrick then asks why he would still want him if he no longer needs a host to survive, and Zen-Aku tells him that he wants to rejoin with him for the power they had once had when they were together. Merrick refuses, telling the Org that he would never ally with him again, but Zen-Aku says that he has no choice and prepares to strike him with the killing blow.
However, before Merrick can be destroyed by Zen-Aku, Alyssa morphs and saves him just in the nick of time. Both she and Merrick end up going over the cliff and into a nearby river, and the other Rangers keep Zen-Aku distracted so that he won't pursue them.
Alyssa and Merrick are washed up out of the river and she offers him assistance, but Merrick is angered and scolds her for interfering in what he thinks is his battle only. She protests, almost saying that he could have been destroyed but Merrick cuts her off and says that it doesn't matter. Alyssa further protests that she and the others are his friends, but Merrick, feeling responsible since he was the one who unleashed Zen-Aku, tells her once more that he must handle the rogue wolf Org on his own. He then summons his Wolf Savage Cycle, morphs once again and heads back to the battlefield.
The other four Rangers at the scene continue to struggle against Zen-Aku, but Merrick soon reappears on his cycle and charges at him at full speed. Once they are in the immediate vicinity of each other, they both hit each other with attacks at the same time and end up disappearing after going over the hillside. Alyssa shows up and his Savage Cycle reverts to his Wolf Animal Crystal. Alyssa picks up the crystal, filled with worry and fearing the worst.
Later, on the Animarium, Cole notes to Princess Shayla that Zen-Aku seemed more powerful than before. The Princess explained that once Merrick had put on the cursed mask all those years ago, the evil power that it held was divided between the mask itself, Merrick, and his three Wild Zords. Taylor realizes that now that the curse is broken and Merrick and his Zords are now free, Zen-Aku now has all of that evil power to himself. Alyssa continues to wonder about Merrick, still fearing the worst, but Princess Shayla can sense that he is still very much alive and out there somewhere.
That night as Merrick finishes bandaging himself up, Zen-Aku confronts him once again, telling him that trying to escape him is futile and to give in, but Merrick refuses, saying that he can send him back to the spirit world just as easily as he brought him into the mortal one, and a battle then ensues once more. Merrick puts up a good fight and soon morphs. The two continue to fight as the hours of the night and early morning go by.
Up on the Animarium, Princess Shayla continues to hold onto Merrick's Wolf Crystal and she suddenly hears the Wolf Zord howl into the night. The Rangers are awoken by the Wolf Zord's howls and Cole realizes that he is stating that Merrick needs help.
Both Merrick and Zen-Aku continue to battle until after the sun has risen, and Merrick is finally too badly beaten by Zen-Aku that he falls back and demorphs. However, before Zen-Aku can finish him, the Wolf Zord appears in his Savage Cycle form and knocks Zen-Aku away, saving Merrick's life and the Ranger gladly thanks him for it. The other Rangers then show up as well, and start to finally get through to Merrick that the Power Rangers are supposed to work as a team. Though he is reluctant to let them help at first, he finally accepts their help and all six Rangers morph into action.
Zen-Aku is ready for battle once again and is more than willing to destroy the other five Rangers along with Merrick if necessary. He is powerful, but as a team, the Rangers are able to bring him to his knees and come close to claiming victory. But Zen-Aku says that they have not seen a fraction of his new power yet, and is able to grow to gigantic size without the use of growth seeds.
The Rangers summon their Wild Zords, forming both the Wild Force Megazord in Striker Mode and the Predazord. The Rangers are taken by surprise when Zen-Aku appears to be able to stop and catch/intercept the Armadillo Zord's final strike attack and are hit hard when he throws the attack back at them. He begins to gloat, stating that he can't be beaten, but Merrick, seeing the Armadillo and recalling the special move that Willy had shown him the previous day at the pool table, refuses to back down and performs the move using his Gator Staff as a cue and the Armadillo as a cue ball. Zen-Aku is taken by surprise and the move appears to precisely mirror Willy's and be quite effective on him, cutting off his horn and weakening him. Merrick then takes the opportunity to strike Zen-Aku with the Predazord's Revolver Phantom attack, putting an end to Zen-Aku for good and watches as the Org crumbles to dust.
After the battle, the other Rangers congratulate Merrick on the beach for his teamwork and victory, and as a result of their win they decide to throw a party on the Animarium. Merrick is still uneasy around his friends, however, and when asked if he will come to the party, his response is simply, "We'll see."
Later at the party, Merrick does not show up and the Rangers are slightly bummed, but Princess Shayla tells them not to take it personally as he has always been quite a lone wolf and suspects that he is celebrating in his own way. This proves to be correct as he returns to Willy's and readies himself for another pool game with him. Merrick thanks Willie for teaching him the move he showed him earlier and the two resume their earlier game that hadn't started yet, with Willy saying that it was still his break.
