.g is a very unique Pokémon because of the fact that it has two sprites and three different Pokédex entries. .g may display the player's name multiple times in the bottom of its Pokédex entry.
In all three possible Pokédex entries, the height and weight are different: 23'0" (ca. 7 m) and 880.6 lbs. (ca. 400 kg.), 81'64" (ca. 26 m) and 2054.5 lbs (ca. 930 kg) or 81'80" (ca. 27 m) and 2056.1 lbs (ca. 930 kg).
Its species varies as well, it can be (player name 11×), (player name 6×), or a long string of glitched characters.
Although .g is part Bug-type, it doesn't learn any Bug-type moves.
