Albert

Albert is an antagonist in many Talking Games, frequently Breaking the Fourth Wall, and reminding characters that they are, indeed, fictional. He is the Arch Enemy of Trebla.

Origin
The earliest known use of "Albert" was in a Club Penguin card game, someone said "You know, we're just cards being controlled by hands," and then someone else said "You're being like Albert Card!" and from then on, Albert has been used as a term for breaking the Fourth Wall.

Siblings
In most of the earlier Talking Games, Albert was thought to have many siblings, Including, but not limited to, Albert Card, Albert Talking Game, and Albert Pokémon. In a later game, Po figuered out that all of Albert's siblings were actually one person, with the ability to cross Universes. Po almost apprehended Albert, but he escaped into The Void before he was caught.

It is also speculated that Trebla is his twin brother,

Misconceptions
It is often thought that Albert is the primary antagonist of all Universes, but that is not exactly true. While Albert and Trebla are usually portrayed as main Villan and Hero, respectively, Albert has not done much evil to be labeled as such. While his constant breaking of the Fourth Wall can be annoying, there are much worse evils out there.

In Lucid Dreaming
Though Alberts antics are usually bad, in Lucid Dreaming they can help quite significantly. Albert has been known to spontaneously appear in dreams, saying "You know, we're just thoughts being controlled by minds," effectively informing the dreamer that they are, in fact, in a dream, therefore helping them achieve Lucidity; And if not, at least they know all the events in their nightmares didn't happen.
