This page lists content in Pokémon Uranium that was either planned to be in Pokémon Uranium but was scrapped, or content that was removed/changed.
According to a post in DeviantArt made by Twitch, Ultichim was supposed to be a mid-stage evolution of Chimical, however, it was not included in Uranium.
Bukial and Velbone lines
Two evolutionary lines were originally planned for Uranium's release-Buckial and Bucksaur, a Rock/Fire type line, and Velbone and Velociskull, a Rock/Dark type line. Given their Rock typing and dinosaur-based designs, it's likely these were originally planned as Fossil Pokémon. They were replaced by Glaslug, Glavinug, S-51, and S-51A.
Preyter and Preyuder
According to a post in DeviantArt made by JV and to info in the Pokémon Uranium Tumblr, there would be two Ground and Grass-type Pokémon Pokémon known as Preyter and Preyuder. They were scrapped and replaced by Corsola and Corsoreef.
Tinead and Zumbread
An official post by JV shows that there would be 2 Pokémon with unknown typings called Tinead and Zumbread (sometimes referred as Zubread or Zubrad). They were scrapped in a later beta.
Swablu and Altaria
According to a post in DeviantArt made by JV, the official Pokémon Swablu and Altaria would be in Pokémon Uranium. However, they were scrapped and replaced by the official Pokémon Misdreavus and Mismagius.
