They are not ayy lmaos, they met ultrabeast in the past and now they are free, so Aether decided to create a pokemon that can compete against the UB. One of the first pokemon was Type: Null, but it was a failure. Lillie and Gladion are Lusamine's sons, they witnessed the creation of Type: Null as well as the deaths and suffering of other pokemon, so they left. Aether is bad bc they are trying to stop what they did.
