you cannot catch a Pokemon without a ball...however you can get Pokemon through trades or from another trainer in the game
This is impossible without the use of cheat codes, unfortunately. Only the Master Ball can catch Pokemon without fail.
not without a gameshark
Use the Master Ball if you need to catch a Pokemon without fail. I'd suggest using it on a legendary, though - don't waste it on a common Pokemon.
You get their health really low and use a ultra ball the best
Lower it HP till it turn red and keep throwing ultra ball at it.
Of course, a Master Ball catches any Pokemon without fail, Legendary or not.
There isn't a way to do it. You can just try to weaken the pokémon and put it to sleep.
Yes, you can catch Dialga without a Master Ball. Dialga can be caught with any kind of Poké Ball but Dusk Balls and Ultra Balls would be the better options.
by throwing a pokeball or other Pokemon catching capsule!
You can catch Pokemon without fail if you use a Master Ball. A Master Ball has a 100% catch rate and is recognised by the "M" on the top half of the master ball. Some people say if you throw a normal pokeball an holding L, R and Select it will have around the same catch rate as a master ball though I tried it and it doesn't work.
first you must hurt him and then you can catch him with ultra ball but he may use recover then you must hurt him again then you can catch him with ultra ball and 5% possibility to catch him with pokeball
when you find that Pokemon if you have a master ball with you use a pokeball and you will capture it
