Yes.
yesz it can
No it cannot not even using a TM
To enable your Pokemon to learn Frenzy Plant, you must visit the Move Tutor on Route 228. Obviously you must have obtained the National Pokedex. Note that only Venusaur, Maganium, Sceptile and Torterra can learn Frenzy Plant. As for Pokemon Diamond cheats, I do not have any.
look online and search for online pokedex
There is no TM yawn. Only certain Pokemon can learn yawn/hypnosis/sleep powder/etc.
Pokemon cannot learn Yawn in Pokemon Silver.
Yawn is not taught by a move tutor it can be learned by some Pokemon such as Snorlax also Slakoth and Slaking.
Snorlax, and a few other ones...
See the related link below.
Kadabra will learn it not sure when.
No, not all Pokemon in Diamond can learn Hyper Beam.
How does riolu learn aura sphere in pokemon diamond version?
After you relese the three Pokemon, go there and catch it. The best method I know, is get a Pokemon and get it to learn Evador, weaken it to 1 HP, have a Pokemon that knows yawn, and get to battling!!!! Use those two moves, snag it with a ultra ball and you might get it!!!!!!!
In Pokemon diamond many Pokemon can learn flash for eg. Electric Pokemon such as Pachurisu Pichu and Luxray all (eveloutions) and yeah just experiment and see what can learn flash!
Keckleon Mightyena and oall the pokemon learn using a TM.
Yawn is not a TM.
