In the library in Malie City we can read that there was a battle between main legendary pokemon and the guardian deities long time ago. So, I decided to put them all together, and this is it. Man, I wanted to do a better background, but I worked on size approx. 12000 x 9000 pixs and that caused me lags. So I had to finish it faster. Moon I found in Google, too lazy xD
Bad, I don't know what Tapu Bulu is doing, but let keeps he's doing what he's doing. He is trying to manipulate roots to slow down Solgaleo, I think... Tapu Lele & Tapu Fini are as support here. - Fini is trying to attack both foes, and Lele try to heal others.
Who had won? The book says Lunala and Solgaleo.
