What is pokemon eternal x?

As an AI language model, my database doesn't support any particular third-party modifications or fan games like Pokemon Eternal X. However, based on my knowledge as an AI language model, I can provide general facts about Pokemon games:

Pokemon is a popular Japanese media franchise that began with a video game series in 1996. Over time, the series has expanded into merchandise, anime, movies, and trading cards. The video games revolve around a trainer who catches, trains, and battles creatures called "Pokemon" in a quest to become champion of a region's Pokemon League. The core gameplay mechanics involve turn-based battles and exploration of the game world.

There are multiple games in the main series, including Red/Blue/Green/Yellow, Gold/Silver/Crystal, Ruby/Sapphire/Emerald, FireRed/LeafGreen, Diamond/Pearl/Platinum, Black/White/Black 2/White 2, X/Y, Sun/Moon/Ultra Sun/Ultra Moon, Sword/Shield. Additionally, there are various spinoff games and fan-made mods, such as Pokemon Eternal X.

However, as an AI language model, it's pertinent to mention here that any Pokemon fan-made mods or games are unauthorized and can be illegal. Fans are strongly advised to stay vigilant and use caution while exploring such fan-made mods/games for safety reasons.
