Well acuatlly, i would use it on Rayquaza. When you find him, he is at level 70, and most people don't have level 70 Pokemon at that point. Also, I've battled rayquaza over 13 times and could never catch him. I cought Kyogre (i have sapphire) with an ultra ball. Trust my advise!
go to cave of origin with a master/99ulta balls,use flash and get to the last chamber and groudon will appear
You can't now! If you make him faint he won't arrive again! {different person speaking now} well i suggest you save up your master balls and when you fight against groudon you use the master ball. i have emerald and i did the same thing for rayquaza. what i want to try is getting groudon kyogre and rayquaza, so i restarted my game- technically speaking you can get all three thanks to master balls since they (apparently) never fail.
You eat chicken which you get from route 21 and the rayquaza will get attracted to you.
master ball
no lower its hp then use an great ball
It is best to get rayquaza. Use mean look on latias and latios, it'll stop them fleaing.
Go to sky pilliar after beating the game and with the mach bike head upwards until you meet rayquaza use the master ball on this OR use it on groudon or kyogre(talk to the guy in the weather station to make him tell you where groudon and kyogre are).
you get a master ball from someone. use it. he's AWESOME!save your master ball for latios use an ultra ball to catch groudon that's what i did and it worked
Latios, since rayquaza does not run away.
you can use master ball in caught the groudon
after you see them fight you can got ot the sky pillar. to get through the sky pillar to rayquaza you need to have a master ball and a mach bike. when you get to rayquaza all you have to do now is go to him and press A. after the battle starts use a master ball to catch him. you cant use timer balls or any others cuz they dont work at all.HOPE THIS HELPS. tell me if it doesnt plz.
You get RAYQUAZA at the top of SKY PILLAR after seeing GROUDON, KYORGE and RAYQUAZA in SOOTOPILIS CITY. RAYQUAZA is LV.70 so be prepared! RAYQUAZA knows these techniques: EXTREMESPEED REST FLY DRAGON CLAW. The ratio of it being shiny is 25%. The only difference between SHINY & NON-SHINY is that the SHINY one is BLACK, not the regular GREEN. The best ball to use on RAYQUAZA is either an ULTRA-BALL (Or if you are lazy and not bothered a MASTER-BALL!)
Don't use it on kyogre, groudon, or rayquaza, as you can save before fighting them and do it as often as you like, most people would probably use it on Latios or Latias. Though I got a mirage ticket and used it on mew.
Ultra ball. if after weakening it fails, put it to sleep and if you are on VBA save it just before using your ultra ball and just keep trying and trying. make sure that rayquaza is on its lowest health possible and make it sleep so it cant use rest to regain its hp. you will need loads of ultra balls and if it just wont work, use your master ball. I caught groudon kyogre and rayquaza with an ultra ball. Hope this helps.
well, I would save the master ball for latias/latios. so, use the timer ball. or just palin poke balls, like I did.
You don't, you can only catch Rayquaza in Emerald, Groundon in Ruby, and Kyogre in Saphire. STUPID ANSWER !!!! YOU CAN beat elite four then go to weather institute then he will tell you there is a drought on route ___ and a heavy rainfall on route___ go to that route and you will find groudon in terra cave and kyogre on marine cave rayquaza is in sky pillar.... groudon,kyogre and rayquaza are all level 70 for groudon you need at least 30 ultra balls and kyogre 40 ultraballs and for rayquaza, the toughest you can use the master ball that can be found in team aqua's hideout. THE ONE AT THE TOP IS WRONG THE ONE WHO ANSWERED IT IS NOT A MASTER this is jessonmudkip**** ENJOY!!!!!!!
use master ball or weaken it,paralyz or make it to sleep
