CELIBI IS NOT IN RUBY, SAPPHIRE, OR EMERALD. IT IS NOT, WAS NOT, AND WILL NEVER BE IN RUBY, SAPPHIRE, OR EMERALD.
You cannot get Kyogre on Ruby. You either have to trade it with someone who has Sapphire or emerald, or get sapphire or emerald. Sorry...
No, it is impossible to trade from crystal to ruby/saphire/emerald. The games are incompatible.
Emerald by far
From what i heard you cannot get KYOGRE in ruby.
you really should get emerald cause Pokemon ruby and Sapphire are separate and emerald is those 2 put together so instead of getting ruby and getting groudon just get emerald and you can get groudon and kyroge and newer Pokemon
you cant trade from ruby,sapphire or emerald you can find it in the safari zone in ruby sapphire or emerald
ruby, sapphire, emerald, fire red, leaf green
