I think the evil team will be a group that wants to make everything more technologically advanced. People who have no care about destroying habitats of pokemon. Why do I say this? In Native American Lore, there are a few different prophecy. One in which is known as the Whirling Rainbow Prophecy. I posted this in the Rainbow Thread before this one. But I will post it here as well.
"There will come a day when people of all races, colors, and creeds will put aside their differences. They will come together in love, joining hands in unification, to heal the Earth and all Her children. They will move over the Earth like a great Whirling Rainbow, bringing peace, understanding and healing everywhere they go. Many creatures thought to be extinct or mythical will resurface at this time; the great trees that perished will return almost overnight. All living things will flourish, drawing sustenance from the breast of our Mother, the Earth."
There was one before this prophecy in the same lore.
"At the beginning of this cycle of time, long ago, the Great Spirit came down and He made an appearance and He gathered the peoples of this earth together, they say on an island which is now beneath the water, and He said to the human beings, "I'm going to send you to four directions and over time I'm going to change you to four colours, but I'm going to give you some teachings and you will call these the Original Teachings and when you come back together with each other you will share these so that you can live and have peace on earth, and a great civilization will come about. "
These four color represent the rainbow. So the Islands may not get along. Also, the island in which is missing, one of the large Hawaiian Islands, could appear after the main storyline after it has been restored.
And now for the reason I think the evil team is what I said.
"In the time of the Seventh Fire, a New People would emerge. They would retrace their steps to find the wisdom that was left by the side of the trail long ago. Their steps would take them to the elders, who they would ask to guide them on their journey. If the New People remain strong in their quest, the sacred drum will again sound its voice. There will be an awakening of the people, and the sacred fire will again be lit. At this time, the light-skinned race will be given a choice between two roads. One road is the road of greed and technology without wisdom or respect for life. This road represents a rush to destruction. The other road is spirituality, a slower path that includes respect for all living things. If we choose the spiritual path, we can light yet another fire, an Eight Fire, and begin an extended period of Peace and healthy growth."
The 7th Fire is the 7th Generation of Pokemon.
I don't think this will be 100% correct, but I think this is what it will be inspired by. The start of this technology could be the man made island. Maybe the evil team destroyed the original island, and created a completely artificial island.
And I am not sure where it came from, but an art peace of a rainbow warrior depicts a Lion, a Dolphin, an Eagle and a Wolf.
