Darkrai = Dark-type, Fighting is super effective against dark.
Fire
flying type and ghost type Pokemon
The expert belt in Pokemon diamond and pearl increases the power of a super effective attack.
Flying and psychic
Occa berry.
The dark type is super effective against it, plus psychic can't hurt them, and the bug type is super effective, but it takes psychic attacks as a normal effective hit. I would suggest using beautifly or kricketune, since there isn't any murkrow in Pearl.
Kabutops is a water/rock type. Fighting and grass will be super effective. Grass is best as it is 4x super effective.
The strongest bug Pokemon are Shedinja its HP is 1, but only super effective moves will hurt him, its mostly unstopabble !!!!!
The main rare Pokemon in pearl is palkia

No. Ghost and Dark is super effective to Psychic Pokemon. Fire is super effective to Grass, Steel, Bug, and Ice.
