yes u can catch a mewtwo. u need to go to cerulean cave and roam around until u reach the centre. there u talk to mewtwo and battle it(save before fighting in cae u kill it).this catching of mewtwo helps but take notice that u catch it with a great or ultra ball. first i caught it with a great ball but then forgot to save it.so the next time i had to use my master ball cause i was bored and irritated. now my team is:
1.blastoise lv100
2.mewtwo lv100
3.zapdos lv100
4.tyranitar lv89
5.magmar lv88
6.snorlax lv96
save your masterball for the legendary dog
1.squirtle-raikou
2.bulbasaur-entei
3.charmander-suicune
Yeah it is possible to catch kyogre with out wasting your masterball you wont have to use it until you see latias and latias requires you to use your masterball.
weaken it and put it to sleep
you can, the catch is fairly easy even without a masterball although I woul use ultra balls if you arent going to use a masterball. I you knock out reshiram without sAVing before hand you can try again after the credits at dragonspiral tower
A fleeing legendary pokemon
try using dusk balls
the strongest pokeball is the masterball. the masterball can catch any Pokemon out of the 493. it doesnt matter what kind of Pokemon it is, the masterball can catch any Pokemon.
Use something like mean look to keep it from running, then catch it like you normally catch a legendary.
No.
Use a quick ball and hope- but if it doesn't work it will flee
the masterball is for any Pokemon you want, it can catch them without fail ( it will ALLWAYS work ) . you are supposed to use it for mewtwo though. :P
no
Use a masterball,parilize it,constently huck balls at it,damage it.
