Dialga learns Time Realm at Lv 90 A nice lady makes Dialga learn Drago blast When you catch him he knows Roar Of Time
teach it dig or other ground type moves.
Dragon and Steel Moves
thunder punch, what else?
Well it really depends on what you are doing and what moves they have. At the moment I have a level 100 Palkia (Moves- Surf, Spatial Rend, Aura Sphere, Earth Power) that is my favourite and the better due to the fact Dialga's level is 88 and the moves i taught are mostly crap (moves- roar of time, earth power, cut, strength). They both do a good job of smashing other Pokemon. I'll get dialga up to level 100 (teach it some good moves) and vs Palkia. I'll get back to you on this one. Yeah I did this and Palkia SMASHED Dialga. But I think it still doesn't matter because you will rarely be versing hard Pokemon.
Jolteon is not one of the best electric type Pokemon considering the only thing good to teach it is an electric type move although you should teach it strategy moves along with an electric type move, moves like Toxic, Helping Hand would be good to teach it and Sand Attack.
Fighting and Ground type moves are most effective against dialga, since it is a dragon+steel type pokemon.
Arceus has the best stats in pearl Dialga is the best for your party. Somehow teach him Draco meteor and roar of time. Best attack in Pokemon ROAR OF TIME!!!!!!
dialga would win giratina is week to dragon type moves
tigi tigi tigi tigi
the orb is for dialga to boost his steel and dragon moves
Feed best pokeblocks to your pokemon, Teach best moves for the contest your entering and just use the right moves at the right time.
His best moves are blizzard teach it to him hydro pump ice beam and (rain dance body slam or calm mind your choice) in my opinion.
