Dokko's Clone's backstory becomes very disturbing when you think about it. The Clone was created by Dokko in his childhood when he was an ill-mannered school ruffian, due to the fact that he had no friends. Whereas Dokko saw the error of his ways and became an intellectual gentleman, his Clone never grew out of itand stalked him around the city, to the point where Dokko left him the number of his house while escaping into the sewers. Now, consider this - Dokko's Clone was essentially born a bully. Being only Dokko's friend, he never socialized with anyone, and it's entirely possible that he is incapableof socializing. As he was also created to be Dokko's friend, it opens another disturbing implication - when Dokko ran away, he robbed his Clone of meaning of life.
The Clone's mental instability is supported by the episode. During the episode, he forms a gang out of him, Dokko and Pin (whom he calls Cipollino), even though they are trying to stop him, which shows that he is under the delusion that they are his friends. When Pin breaks it out to him that he is not his friend, Clone goes to Dokko and says that they need to teach him a lesson, and when Dokko breaks it out to the Clone that he should have changed, the Clone snaps and declares that he will do such a terrible thing that they wouldn't forget it.
Also, his dialogue with Dokko. Dokko says to him that he should have learned something, and the Clone says that Dokko made him like that. The problem? Given the fact that Dokko's Clone would never exist if Dokko wasn't a friendless, ill-mannered hooligan, he is right.
And during his Villainous Breakdown, he mentions that he did learn something. He goes on to crash Pin's house and is chased around by Pin and Dokko, until they tie him up, put him in a submarine and send him away to Pin's fatherland, which is known for its iron discipline. It's revealed that Dokko is the one who got tied up, and Dokko's clone is standing next to Pin. That's right - even as a vulgar, delusional ruffian, Dokko's Clone is capable of impersonating Dokko. Even if they do get Dokko back and put the Clone in the submarine, there is nothing stopping Clone from escaping, given that the submarine was put on autopilot, or, if he gets to Pin's fatherland, impersonate Dokkowhile claiming that the real one is an imposter, and plan his revenge there.
His capablity to perfectly impersonate Dokko is all the extent of his powers we see. We also never see what thing he planned to do with the valley our heroes live in. Whatelsehe is capable of?
We also don't know what he did before arriving to the valley the main characters live in. Now, let's look at the Clone and Dokko's faces when the Clone says that they will teach that traitor (Pin) a lesson. It is also possible that, after Dokko escaped from him, the Clone spent his entire time searching for Dokko. Justwhathedidto those who wereathispath?
Consider: The overall atmosphere in the show - technology, aesthetics and all - resembles the 20th century. Dokko is Ambiguously Jewish, while Pin is obviously German and is somewhat self-conscious about this fact (such as when he speaks about his aunt). ''Dokko isn't coming back.''
If only PCs like the one Dokko has were a thing in 1940s. While later episodes debunked this, Pin's "Vaterland" could've been a secret Nazi base in Antarctica.
Considering that Team Invincible is canon to the show's lore and really is a prequel to the series, then the land of Kikoriki contacting with the outside world to order products and being invited to big events is kind of strange, considering the fact that they're all a bunch of (non-intentional) criminals who illegally passed the outside border and Pin and Chiko even got framed for the act they didn't commit and jailed. A special episode of Pin-Code released in 2021 centers around the Kikoriki passing the census so their land can be considered an official settlement. They basically give away the location of wanted criminals.
In "Truffle", Krash draws Hitler's hair and mustache on Rosa's portrait. Wait a second... Hitler existed in Kikoriki's world?
when the Clone says that they will teach that traitor (Pin) a lesson. It is also possible that, after Dokko escaped from him, the Clone spent his entire time searching for Dokko. Just what he did to those who were at his path?
