no only 2 legendaries are permittted to enter latios and latias

Use a teleporting one or just beat the elite four
I would recommend Ludicolo for its Rain Dish ability is very useful especially if you are in a double battle with a Kyogre.
You cant. You must have Emerald or sapphire (or use cheats)
I remember it is in a cave, where you rescue Kyogre. If you use flash, on the way to rescuing Kyogre, you will be able to see the HM lying on the ground in the same room as Kyogre.
U use surf then rock climb and kyogre should be there
for emerald, raquaza, groudon, kyogre, your starter pokemon, magnemite and wailord.
use dive to get to sootopolis and you can go in after you awaken rayquaza in the sky pillar to stop the battle between groudon and kyogre. After you do that, go back to sootopolis and talk to maxie, archie, steven and wallace.scott is champion
you just need to find it and beat team aqua.so you can go to Mossdeep city.
you can use it to awaken your pokemon in battle
SAVE THE GAME BEFORE GOING IN FRONT OF KYOGRE. Therefore, if you kill him, or die yourself, you can restart. To catch Kyogre, have a Pokemon that know Thunder-wave, and another one that knows False Swipes. (Thunder-wave paralyzes, and False Swipes can bring an opponent down to one HP without killing them.) Use Thunder-wave to paralyze Kyogre, and then use False Swipes. Bring it down to 1 HP, and then catch it. To catch it, I would recommend a NetBall or an UltraBall. (If the battle went on for a long time, use a TimerBall.) Another strategy is to use a Pokemon that knows Flash. (Flash lowers opponents' accuracy.) Keep using Flash until their accuracy can't go any lower. Then use NetBalls, or draw out the battle and use a TimerBall. But Flash is so Kyogre won't really be able to hit you. If you can, catch a Rayquaza (I may not have spelled it right), and use Outrage. Be sure not to kill Kyogre!
Weaken it to red hp, paralyze it then use many net balls or ultra balls.
