Gengar with cool moves

[Water Pokemon Master]

Is there a chain to get Gengar to know Mean Look, Destiny Bond, Perish Song, and Crunch?

[Toothache]

Gengar can't learn Crunch. Mean Look and Destiny Bond he learns by levelling up. As for Perish Song, breed with Misdreavus.

Are you sure there is no possible chain to give Gengar Crunch?

[Bad Pikachu]

Gengar can't learn Crunch at all.

Darn...I was really hoping he could. Thanks.

[Frostweaver]

not really... Gengar doesn't benefit from Crunch besides to defeat other Gengars, which can be done through Shadowball already. You already have thunderbolt, giga drain, ice punch, fire punch and psychic and your disposal already for special attack... isn't that enough?

Not at my local Gengar Compitition.
My neighborhood holds Gengar Trainer battles, and I wanted mine to be Unique. They also have contests, (we trade them to R/S)
Then we battle 6 Gengar Battles, all Double Team. So it's Gengar-Gengar vs. Gengar-Gengar, each battle has 3 subbatttles, cuz 2x3=6.

Anyway, I guess I'll just have to stick with Shadow Ball like everyone else.
