You meet that Cue Ball on Route 54 in Beta 4.xx after you go on this epic "Goku's DRAGON FIST" quest, haha.
After you touch the triangle, the "Bro-lic" Punch guys finally get to punch that big rock out of the way.
That entrance is Wrecktor's Gym because you can see a gym sign on top of the entrance.
----- This guy gives you HM Smash after you beat Wrecktor
Hello the cave is a dead end,the door is blocked,also the hiker saying it a trap cave is it true
Also,I have a very interesting event for you.When in Seijo we will be nearing our league
challenge,one mysterious cave will arise and a peculiar presence(one who saves you when
you lose)will waft around Ignite Heights And create a pathway for route E
The criminal egos atk (Transcend Flare)will open a gateway to that cave in route E
Unfortunately,They will be unable to close that portal,and Frozen,Inferno,Your Third Counterpart
and the hero will reach the cave,but separately.The cave's name will be Legend's Lair.
But you get its news late.All the heroic trainers are on the move(You can take some from
other hacks,custom,or Pokemon)but are crushed.When you reach there ,it is too late.
The Pokemon Keldeo and Victini are seized by Inferno and Frozen,and Your third counterpart
will be angry,He will challenge them both but lose,so he team up with you.But Frozen and Inferno
are nowhere to be seen,they fled.Then the police will think the hero scared them away and you
will be given bravery award but during the ceremony,the news will come,Taejo and Saejo
BOTH in danger.then one divine light will appear(same that peculiar presense)and tell
all the souls whose human form died in Uiyto will give you power to summon Zygarde.
But zygarde has condition,he dont trust your partner.So your partner(Third Counterpart maybe ZX)
will aburptly leave.You will take upon inferno and frozen and defeat them.The champion will
congratulate you,and leave.But you wonder,You have Zygarde one of most powerful
pokemon so no person will able to defeat you so you set on journey to find out.
Is This The TRUTH? (You can make an extra difficult game as a sequel)
The pokemon Required will be Keldeo,Victini and Zygarde.
Please tell me if you like this idea,it might be long difficult to script,solemn,
but i am sure it will be a great finale to your game.
