In Pokémon Infinite Fusion, Gible can be obtained by fusing two specific Pokémon together. Gible is a Dragon/Ground-type Pokémon that was introduced in Generation IV, so you will need to select two Pokémon from the first seven generations that can be fused to create a Dragon/Ground-type combination.
One of the ways to obtain Gible in Pokémon Infinite Fusion is by fusing Dratini and Sandshrew together. To do this, simply select Dratini and Sandshrew in the Infinite Fusion Generator, then click on the "Fuse" button to generate the Gible fusion.
It's important to note that the resulting fusion may not necessarily have the same stats, abilities, or moves as Gible. Instead, the fusion will have a unique combination of traits that is based on the selected Pokémon's attributes. Additionally, not all fusions will be viable or balanced for gameplay, so it's up to the player to use their judgment and select fusions that make sense and fit their gameplay style.
