They are taken to a Colosseum to fight in the ultimate final challenge, which features numerous obstacles and the return of a few old faces. One contestant wins the support of the entire the crowd, with one exception. In the end, one contestant wins the challenge and the money, and someone gets his long-awaited karma.


Cam Lightning Finalists

Lightning bullies Cameron before the final challenge.

The episode begins after the events of The Enchanted Franken-Forest, and Cameron is disheartened that Zoey didn't make it to the finale. However, Lightning is happy, because it will be much easier to win the million dollars due to Cameron's lack of athleticism. Cameron tells him that even though he isn't that strong, he still has as they call it "game." Lightning shows his "game" by lifting a log over his head and saying how he's got it in the bag. Cameron points out though that he could not win if the last challenge is an intellectual one, but Lightning points out that past Total Drama finales have always been physical and states that he can crush Cameron like a grape.

In the confessional, Cameron is shown not to be worried, but terrified. However, he mentions that he has come a long way and how he can do anything if he can beat Lightning. After he says that, Lightning scares him saying the same grape threat. Cameron says on the other hand if Lightning wins, he will still have a bubble to stay in for the next sixteen years growing his skin back while eating his mom's sandwiches through a straw. Lightning screams the word grape making Cameron even more terrified. He says to his mom if she's watching this to start pumping out the oxygen.

Lightning is then in the confessional saying while doing curl-ups at the same time, if he was a gentleman he would let Cameron win, (referring to him as a "little girl"). But he states that his father didn't raise a gentleman and that the victory will be his before getting scared and falling down due to the horns playing in the background.


Lightning hurts himself when he hammers on his "helmet".

Later that day, Chris is seen being pulled in a carriage with a television; it shows the two finalist's parents, being able to video chat with them. Cameron's mom is first seen talking to him. She had told him since purified air costs so much, she won't be able to afford his bubble. Cameron seems shocked while his mother needs him to win the million. Next is Lightning's father, but only seen from his backside. He is also saying that his son is going to win the million while he's being interviewed. He even bet his championship rings. Lightning seems nervous with the heavy toll he holds now, while his father says he's nothing without them. The video then shuts off, while Lightning never got to actually speak to him.

The final two and Chris are seen in the carriage as they approach the "Chrisiseum". Once inside, Chris then shows the eliminated contestants. Cameron then asks what happened to Scott, who is now in a machine. Chris says that his machine helps him say "yes" and "no", since he can't talk. Sam then asks if he has to cheer, while Chris says it's mandatory to cheer, or else Fang will be released on them. Chris then announces the final challenge, a gladiator battle royal. The first part is to create armor out of a massive junk pile dumped next to them. Chris then says they have fifteen minutes to assemble their armor, but to also be careful for booby traps.

Cameron's power armor.

 Lightning first starts out pushing Cameron as he goes back and forth in front of the Peanut Gallery, who are cheering and helping him build. Cameron then finds a computer and a HazMat suit. When he pulled on the suit, a bomb goes off in front of him. Lightning then makes fun of him and continues working. But Cameron then spots a blowtorch that is next to Lightning, which he could use. Later on, Lightning has his suit armor almost complete, while

Cameron uses a computer, powered by the Marshmallow of Toxic Loserdom, to program his armor. A quick montage is then seen between the two preparing, until the fifteen minutes were up. Lightning is seen with his armor which everyone cheers him on, while he makes fun of Cameron, who only has a suitcase. Cameron then kicks the case, releasing a which self assembles onto him. Lightning is stunned by his suit of high-tech, power armor.

Dakota vs. Mutant Turtle 2

Dakota fights a mutant turtle to save Sam.

Chris then announces part two, where the rules are, whoever pins the other for three seconds first win. The battle then starts with Lightning going after Cameron. Cameron then blasts him, causing him to fall down. Chris then brings in the mutant beetle that shoots fire at Lightning, while he runs towards Cameron and punches him. He then falls down, powering his rockets on the bottom of his feet, blasting the beetle out of the ring.


Cameron and Lightning fight in the challenge.

Lightning then attacks Cameron multiple times with his weapon, which causes Cameron's suit to lower in armor strength. Chris gets bored of the battle and brings out a mutant alligator. Cameron blasts out of the alligators mouth, while he picks up Lightning who punches him from below. Cameron then punches the alligator in the stomach, sending them both flying. Lightning is able to land on the ground in a split formation, injuring his groin in the process. Mike then tells Cameron to pin him, but Lightning gets back up, keeping the fight going on. Cameron fire his blaster arm at Lightning, but he manage to deflect one of the shots out of his way with his club. One of the shots ended up in Chris's chair hitting his remote. The remote then malfunctions, causing all the mutant creatures on the island (and Ezekiel) to appear. Zoey, Mike, and Scott are seen traumatized in the confessional after seeing all the animals again. The animals then attack the eliminated contestants, causing them to go into the ring with Lightning and Cameron. Anne Maria is seen confronting a mutant squirrel, and the squirrel shoots her hair. Ezekiel then comes to save her and leans in for a kiss as she screams. 


Lightning gets struck by a literal lightning.

Cameron then gets worried about his endangered friends, while Lightning attacks him from behind and almost pins him. Cameron then throws him off causing his helmet to also fall off. Cameron then uses the helmet to save Anne Maria, knocking out Ezekiel. Anne Maria then hairsprays her hair to fix the damage done to it.Dakota is seen attacking a mutant turtle holding Sam, while Dawn says her tea leaves didn't predict B getting punched by the octopus in the tree. Staci is also seen getting eaten by Larry, talking about her ancestors as usual. Cameron then blasts Larry in the privates, as he runs away. Lightning finally comes back to hit Cameron once more, getting rid of all of Cameron's armor strength all together. Cameron then orders the armor to transfer all power to create a magnetic field, which finally shuts down Cameron's armor. Everyone is then stunned when it appears nothing has happened Lightning then tries to attack Cameron one last time, but everything starts to get attracted to Lightning's armor. Cameron then tells him he turned him into a magnet, causing everything magnetic in the field to be pulled towards him. A storm cloud nearby strikes Lightning, causing everything to get blasted away from him and turns his hair white. However, Cameron also couldn't move as he uses the last of his armor's energy for the last attack. Depending on the ending, one contestant fall over the other and wins the challenge.

After collecting his reward, the winner leaves with the other contestants on a boat driven by Chef. Chris then starts to sign off, but before he does, he reveals that he placed a bomb at the bottom of the boat. When he pressed the detonator however, the dock explodes underneath him explodes instead. Chris realizes that Chef has switch the bomb's position and yells at him. Chris then resumes his sign off, when suddenly a flock of helicopters surround the island, saying that the island is now under government protection.

When Mike asks what Lightning will spend the money on, Jo asks for 10% due to her getting him to the finals in the first place. Sam offers to play any video games that Lightning needs to beat, but Lightning rejects both of them and says that he's spending it on his own stadium so that he can get in shape for football season. Chris pulls out an X-ray of Lightning's body following the challenge and advises him to avoid physical workouts for a while, but Lightning says that pain doesn't matter to him.
