Tyranitar is one of the most strongest pokemon in the game (in my book that's true its ok if you dont like him) A lone tyranitar with the moves earthquake rock slide crunch and fire blast or flamethrower can take on a lugia ho-oh entei and raikou and mew and celebi and mewtwo and the legendary birds. to get him go to the building next to the celadon casino with 8888 coins. the clerk will give you a lv 40 larvitar for 8888 coins(the one to ure right). Note: if you're worried you are not going to get the gender you want then save in front of him.
