IMPERIAL THOUGHT FOR THE DAY: SUFFER NOT THE ALIEN
The first stage of the Charizard line, it is at this stage, almost immediately after hatching, that training and hypno begins. Most Charmanders do not pass the harsh training, either being maimed or killed. Those that due survive however, go on to evolve in to its later stages.
The second evolution of the Charizard line, it is at this stage that this Pokemon first sees battle. It is usually given to Commissars, High Ranking Officers in both the Imperial Guard or Imperial Navy, or Space Marine Chapters, to further improve its abilities further. Its claws are known to cut through Carapace Armor with some difficulty, though it fails to penetrate power armor.
The final evolution of the Charizard line, and a powerful but rare beast. Charizard is rarely seen outside of Space Marine Chapters, it's temperament being too much for most people. However, those that earn its respect go on to be powerful beings indeed. Legends say that Primarch Vulkan himself owned one. Whether or not his is true, remains to be seen.
