:Frown: I should kill Articuno or leave him alone?
well you cannot say for sure articuno will be uncatchable from the rumours i have heard and the plans for this game is that legendaries will be available also atm there is no possible way to catch articuno or other birds you can only battle them. After battling them they fly away and will be available at another point of the game all legendaries with base stats of 601 or lower will be available probably this is only rumours i have heard do not get your hopes up, but there is a light :).
