No one knows. If they actually faced off, it would lead up to cataclismic events that puts the entire world at jeoperdy.
i think kyogre is most strong because fire dosent hurt water but water hurts fire.I think that Kyorge is stronger because Groudon does have a grass type move (Solarbeam) which can take out Kyorge. But Kyorge has lots of water type moves so it can take down Groudon easy.

no you just need a groudon/kyorge
in the emmbered tower once you have kyorge and groudon
if saphire, pwn kyorge and the doors should open. if ruby, pwn groudon and doors should open. if emerald, wake up rayquaza to get him to stop kyorge and groudon from fightin.
you go back to the cave where you caught groudon/kyorge
Sadly, you can't, you can only catch groudon, but, if you get both, you can catch rayquaza!
you trade kyorge from heart gold and go back to the place you caught groudon
catch the 1 then trade it over to the other game then battle the other with the 1 u have (.E.G. catch groudon trade it over to sapphire and batte kyogre using groudon,or do it the other way around)
you get groudon by trading then go to prof. oak and he will give you the jade orb to catch raquazza. if you guessing where raquazzas at hes at the embedded tower just like kyorge and groudon
to get raquaza you must beat red at mount silver PS at the top of mount silver. then get your new starter Pokemon from proffeser oak. then go to mr.pokemons house he will give you the red orb (if you have soul silver but blue orb if you have heart gold then go to the embrered tower on the way to the safari zone when you go there you will see groudon if you have the red but kyorge if you have the blue orb once you capture groudon/kyorge try to get kyorge/groudon off your freind then take them both to prof oak he will give you jade orb go to embered tower he will be there
You simply cannot. When you catch Groudon, Prof. Oak will tell you you cannot catch both Pokemon on your own.
