I don't think you can.
you need the blue orb which is only obtainable in heartgold
The best thing you can do is use a master ball or weekin it then give it a ubnormal weekiner EX/ poisin or sleep
it is the same as soul silver after you get your kanto starter go to mr.pokemon and he will give you the blue orb ''kyroge is at lv.50
you must first catch all the regis then go deep inside hippowdon temple until you find a portal that wasn't there before
Go to sotopollis and then to the cave of origin(this can b only done after beating Archie in the underwater cave where u found the submariene.)
lickilicky, the evolved form of lickitung
Starly, Pachuritsu, or Munchslax
Embedded Tower.
in the begining, the world was empty, and then came groudon and kyroge, kyroge made the oceans for water pokemon, and groudon made land for land pokemon. soon kyroge and groudon started fighting for more space and it eventually got out of control, then rayquaza came and stopped the fight with an extremely powerful hyperbeam attack, then kyroge and groudon fell into a deep sleep...........
