I cant kill Dialga

It'll also help if you'd tell us what your current team is. First off, you need to level up quite a bit more. I was at around level 65 when I beat Dialga. You also can get a bunch totter, and sleep seeds: to make Dialga fall asleep, and to confuse Dialga for easier attacks on them. If you have a fire and water type Pokemon on your team, I suggest you give them Flamethrower, and Hydro Pump. Just those two moves will do quite alot of damage on Dialga. Do all of this, and you should be fine fighting Dialga.

Hope this helps,

All you have to do is buy a lot of reviver seeds and if there isn't any, go to beach cave and come back and it will probably be there. Also dialga is a steel type so fire works great!!! -SonicSpeed32

If you die don't turn your game off, because you still keep your experience points.

I had a level 50 charmander and a level 50 squirtle and defeated him without any reviver seeds.I linked protect and flamethrower for charmander and protect and hydropump for squirtle.Piece of cake you can buy protect from the kecleon market or sometimnes find it in the hidden land or temporal tower dungeons.

get a tm f dig and use it on dialga the third time he should be defeated

I used a x eye seed then used energyball followed by giga drain my partner used water pulse then when dialga went back to normal in sight I threw another x eye seed the kept using the same move if you pick all the seeds up in the dungeons you stand a good chance of winning

I have a bulbasaur lv. 48 that knows seed bomb, vine whip, razor leaf, and energy ball. My partner is a piplup lv. 47 that knows hydropump, drill peck, bubblebeam, and whirlpool. Yet I still can't defeat dialga. Plz help.
