The reason to think they might be possible RS units is because you don´t use the base units to get the omni evolutions. They are completely different. Alfa is now a fire omni unit and Zevalhua was said to be an earth omni unit. You will recieve the 2 as omnis after beating their trials, the base unit earned from previous trials will remain untouched.
