It is not known to evolve into or from any other Pokémon, despite its close resemblance to Goomy. However, while CyberGoomy is not necessarily an evolution of Goomy, it is known to be a Goomy that has been equipped with "high tech weaponry."
No method exists to legitimately obtain CyberGoomy in-game.
CyberGoomy appears once in-game as a Pokémon used by Elite Four member Wilson and is one of the so-called "Six Kings" of his team used in the Hall of Masters. Not much is known about CyberGoomy aside from the fact that it was synthetically created, as described by Sir_Willis_CMS in the data given from the "Hall of Masters Laboratory Records":
CyberGoomy, the terminator. Regular Goomy equipped with high tech weaponry. Very dangerous, though completely normal without equipment. Extremely dangerous, even more so without equipment.
Because CyberGoomy cannot be obtained by the player, it is not possible to obtain a full list of the moves it is capable of learning. However, there are a few moves that are known from the player's Sigil Hall battle with Wilson.
