Dragonize

In game description

The Pokémon's Normal-type moves become Dragon-type moves and their power is boosted by 20%.

Using Dragonize in Cobblemon

Abilities are passive and always active, so Dragonize costs you nothing to run. If it is marked hidden on a species above, expect it to be harder to obtain: servers differ in whether hidden abilities come from breeding, an Ability Patch, or events.

See the Pokedex for which abilities each species can have, and IVs, EVs and breeding for how to actually pass one down.
