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.
Dwebble and Crustle
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.
Swablu and Altaria
Munna and Musharna
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 for unknown reasons.
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.
Old Fire-type Starter Pokémon
Scrapped Nuclear Pokémon
Originally, Pokémon Uranium was a Gen III (RSE and FRLG)-styled game. Then it evolved to the Gen IV style (DPPt and HGSS) and finally adopted the Gen V battle interface and Gen VI battle mechanics.
There would be a mode (announced shortly after Burole Town) where Pokémon would race in a similar fashion to Pokéathlon. It was scrapped in a later beta.
