This is how it all started.
Delilah,a young Green wolf full of adventure and love one day came along and met three members of a gang called Team Galactic,Saturn was impressssed with Delilah's skills as a trainer,she had joined Team Galactic only recently,she had helped them in new missions that they planned with Saturn as the new leader now.
One day Delilah went out to go and search for her Lucario,Blue,Blue was raised from a egg Delilah received from Riley,Blue has grown strong and is loved by Delilah so much,but then Delilah had stopped and felt a strange energy surrounding her,then she closed her eyes using the power of her Aura energy from being with Blue for a long time,after Delilah opened her eyes she saw nothing but then got a glimpse of a Pokémon,this Pokémon was unlike any other,it was Arceus,the god of all Pokémon.
Arceus appeared before Delilah,and said to her "you have been given another strange energy,a power that will let you become a certain animal forever,you can no longer be humans anymore" Delilah was surprised from hearing this,Arceus then continued and said "choose the friends you want to take with you,you are going to continue living life with them and and in a different place,no longer in Sinnoh.
Delilah had chosen her friends,then Arceus released a energy unlike any other and Delilah was then transported and saw she was in a differnet place now that didn't look like Sinnoh or any other region at all,and she saw her friends as a creature she knew of known as wolves,then Delilah looked and saw she was one too,so then Delilah realized that her and her friends now live life as wolves and so will she,delilah will now miss all of her Pokémon,but that wasn't until Blue and her other Pokémon appeared before her,and all of her friend's Pokémon appeared as well.
Delilah suddnely realized that she will agree to living this life,she was made Alpha now and she made Saturn an Alpha as well so what she did was that in order to have someone take there place as new Alpha leaders for when they are gone they planned something but didn't know just yet,that wasn't until Arceus appeared and said that they wouldn't die and that they would all live forever,but Delilah insisted on still wanting to have a child though to atleast build the pack even more,and she even gave the pack a name....The Galactic Wolf Pack.
