User blog:Steven Bomb 17/Shadow Pokemon

I've been thinking about Shadow Pokemon and Nihilego lately. Now I know that Nihilego came after the Shadow Pokemon where made but this is an in universe theory so we can pretend that little rule doesn't exist. So there was something that didn't make sense to me about Shadow Pokemon, now I can believe that closing a Pokemon's heart might cause a dark aura and will make that Pokemon lash out at everyone. But why does it give shadow moves? These are moves that can hurt every type but why do shadow Pokemon gain them? Well let's look at Nihilego, these Ultra Beasts can bring out the full potential in anyone who it injects with neurotoxins. What if one got through an Ultra Wormhole and Cipher found it? They discover the neurotoxins can help with their plans but due to the fact that too much neurotoxin can cause their victim to become comatose and they only want to protect Nihilego so they modify it. The first few prototypes are a relative success, a few bugs in their programming but nothing further modifications can't fix. The second set is better though they still have the problem of opening their hearts. With Shadow Lugia they perfected the process just enough so that the Pokemon can't be purified. The purification chamber is able to combine the regular process with a procedure that takes out the neurotixins.
