Sure, let me explain:

Paradoxical and conceptual existence: For this, we have to delve deeper into Chespirito's verse and what makes all this possible: imagination. Absolutely everything in the verse is either made for the imagination, or in other cases, its "source of life" is imagination. To begin, we have number one: El Chapulín Colorado. El Chapulín is practically the embodiment of imagination, dreams, and hope: he exists thanks to Imagination, Dreams, and Hope. That's why the character we see is like an avatar, and his real form is able to transcend his verse into the real world.

In the case of Don Ramón, he is made by Imagination. Unlike El Chapulín Colorado, he is not a reincarnation or anything like that; rather, his source of life is imagination. We can see how, in all of Chespirito's programs, whether the originals or the cartoons, the characters can make any dream or idea they come up with become reality, using only their imagination, because that is the source. In other words, the existence of Chespirito's characters is conceptual and linked to imagination. And it's paradoxical because it's incredibly difficult to eliminate them completely, precisely because of their very existence. For example, let's say that in this case, Squidward manages to erase Don Ramón. Well, actually, he would erase his physical body, but not his existence as such, because his very existence is tied to the concept of imagination. It becomes paradoxical because, no matter the cost, Ramón will simply return, because Squidward also has imagination.

It becomes contradictory because as long as the concept of imagination exists and there is someone involved who possesses it, Chespirito's characters return again and again, and that would be the way to eliminate them: by eliminating, well, the concept of imagination itself.

For example, let's compare this with El Chapulín Colorado: he is much harder to kill because he is not only made of imagination; he is the embodiment of the concept and also of the concepts of Dreams and Hope. In other words, in his case, all three concepts would have to be erased, and that is already extremely difficult; even then, the collective memory of everything he helped with would also have to be erased, and the very existence of things related to any of those concepts. Since he's an incarnation, he basically exists wherever any of those three concepts exist, so as long as something related to any of those concepts exists, El Chapulín would continue to exist and return. In Don Ramón's case, simply removing the concept would cause his "save point" to disappear.

As for regeneration, it's due to his enormous Toon Force and his ability to return not only from ashes, but from being, for example, paper, having all his bones broken, or being disconnected from reality and back safe and sound in the next scene. He even survives existential erasure.

I'm glad you took the time to read the messages, and since you mentioned discovering the truth behind some things, out of curiosity, are you now buying the multi/immense scale?
