Over the last few months, the source codes for various Pokemon games have leaked online through 4chan, allowing dataminers to discover hidden secrets that never made it into the game's final product. Pokemon Diamond and Pearl's source code leaked back in May, and dataminers have now discovered some of these same secrets.

Presented by the Pokemon historian, Dr. Lava, some new leaks for Pokemon Diamond and Pearl reveal some of the sprites of Pokemon used in the games' beta versions. Viewers can see Garchomp's sprite, Rotom's sprite, the sprites of Legendary Pokemon, and the sprites of dozens of other Pokemon.

The accuracy of the look of the beta sprites varies to that of the canon designs. Pokemon like Garchomp and Togekiss almost look and feel nothing like their counterparts. Beta Garchomp's entire color scheme differs, and it takes a more rounded appearance than the final version. Beta Togekiss looks a lot more sinister than the bright-eyed final version it turned into.

Giratina follows this same pattern: Its beta version looks like it could be a Fairy-Type legendary dog rather than the deity of anti-matter. As for Arceus and Rotom, Dr. Lava describes them best, calling them "placeholders," as they don't really look like seriously considered designs. Some fans point out that Arceus' beta would work if it were some kind of mysterious, Lovecraftian-horror Pokemon.

Out of the four rarest beta Pokemon revealed, Darkrai's design is the only one that looks similar to the final version. The majority of the collection of regular Pokemon also seemingly look like their final versions. If one were to look at them alone without the side-by-side comparison Dr. Lava provided, it would still be fairly easy to tell which beta designs go with which Pokemon.

There are also some instances of scrapped gender differences or how the looks of some Pokemon would vary depending on whether or not they're male or female. Pikachu's gender differences made it into the game more or less, but Wobbuffet, Espeon, and Chimecho ended up entirely scrapped. Had Espeon's been kept, it would have been interesting to see if Game Freak did the same with the other Eevee-lutions.

Dr. Lava alludes to having more beta versions to post on his Twitter, but these are it as of this writing. However, other Pokemon game beta leaks include the infamous Space World demo of Pokemon Gold and Silver and some evidence for Pokemon Yellow having a counterpart called Pokemon Pink.
