You Will Have To Battle Trainers Red And Blue In POKEMON SUN And MOON

Famous trainers Red and Blue will be waiting for you in Pokemon Sun and Moon! Professor Oak's grandson and the character you play in the first game will be ready to battle presumably in the late stages of the game, although it never really specifies in the trailer. 

In addition to that we also see the final evolutions of the starters (which we revealed in a leak last week), some more Pokemon, and special moves. See it all in the trailer below! Pokemon Sun and Moon releases November 18th.
