First you need the HM which is given by one of prof oaks aides on route 2 he's in a big building but to reach the one he's in you need to cut down the tree on that route and go to the path behind it follow it upward to find the building go inside and talk to the oak aide he will ask if you have recorded 10 Pokemon in your pokedex say YES to get HM05 which contains Flash.
you have to talk to misty, if she doesnt give it, then you didnt beat her, then when you beat her, she will take you to her house, then she will say that in order to give it to you, you have to have sex with her, then she will give it, and you are done!
You go through diglett cave and go to the building and the aide will give it to you for having 10 different pokemon.
HelloSorry to say but you cant trade Pokemon from pearl to leafgreen but you can migrate Pokemon from leafgreen to pearl via the pal park
No migrate him from firered or leafgreen to get him.
to catch Pokemon you have to obtain raikou palls
Yes put leafgreen in the GBA slot in your DS and put Diamond in the DS Slot play Diamond and choose migrate to leafgreen follow the instructions then choose six Pokemon to migrate after your done go to the pal park to capture the 6 Pokemon you chose.
All you need to do is: talk to the man in artitian cave, and he will give you HM05 (flash). BUT, you can only use it after you have defeated the second gym leader. Once you have, go to the cave's basement, and as you can see it is scary dark. Go and teach the HM to a Pokemon, then press START, and then POKEMON, and go to the Pokemon that knows flash, press A on it, and press flash. As you will notice, the cave will light up. You can not light it up all the way as seen in the older generations of the Pokemon games... This can be used for all caves that are dark. Well I hope this message helped you loads. :)

You need the HM5 Flash.
to learn flash you should have pokiemon up to 10
you have to teach it to them
The HM's that are in leafgreen are: Cut, Fly, Surf, Strength, Flash, Rock Smash, Waterfall.
Surf is a HM so you can teach it to multiple pokemon.
hyper beam
The Pokemon are Bulbasaur, Ivysaur,Venusaur, Geodude, Abra that's all I know!
yes but you have to get the TM first
yes,let the Pokemon you want to lean a move and teach it
there really is no Pokemon that know flash naturally but you can teach it to a Pokemon
Many like Bastiodon.
