once or have action replay
i think five maybe but after you beat the Pokemon league you can battle him as much as you want at the fight area on weekends
after you beat your rival at battle tower he will reappear every so often
no there isn't. no trainers have scizor, dusknoir, electivire, magmortar or rhyperion. unless you use find a partner in the battle tower that might have one then no. parnters in the battle tower often use very rare Pokemon but the Pokemon you see in the fights are not recorded on to the pokedex.

"How do you quickly make a Pokemon's friendship with you higher on Pokemon diamond?"You should first give your Pokemon the item soothe bell, then you should place it in your party(works quickest if you put it in the first slot), and finally you should battle with it more often to quickly make your Pokemon's friendship with you higher on Pokemon diamond(or on any other game).Here is a list of things that you should avoid doing, as they will lower your Pokemon's friendship with you.:Let your Pokemon faint to often, let status effects linger(e.g.; poison, burn, paralyze, etc.), always leave it in the PC, and not battling with it.
Diamond dust is mythical and made up by the creators of pokemon!
Pokemon Pearl is a more ''girlier'' version compared to Diamond from my opinion and from most game reviews. Another difference is that the rarity of Pokemon which come out more often and which Pokemon hardly come out. I prefer Pokemon Diamond and I am a female so it depends on your choice.
you get them every so often in the Day care center in Socleon:)
Not at all. In fact, you don't even have to battle any of them (as often seen in speed runs).
Ask jeaves OR watch pokemon more often How do u beat a dinosaur on pokemon
Unown (often wrongly spelled as Unknown) is a Pokemon in the Pokemon series. If you catch one of every type, a new part of their cave will be opened.
Entei, Raikou and Suicine are often referred to as the Legendary Beasts or Legendary Dog pokemon. They aren't in Diamond, so you'll have to trade or migrate them. You can do this from the following games: FireRed/LeafGreen, HeartGold/SoulSilver and OmegaRuby/AlphaSapphire.
Battle with it a lot, and treat it good, like healing it often, medicine or pokemon center, and, just, give it a lot of attention Hope this helped :)
