In Pokémon Deluge, some Pokémon may look different than normal. These Pokémon are: Metallic, Ghostly, Shadow, Dark, and Shiny. (Listed most common to rarest, normal Pokémon being first of course, since normal Pokémon do not have an ability). Each type of Pokémon has a special ability.
Cannot be effected by status like burn, poison, confusion, sleep, and freeze. This ability is nullified by Shadow Pokémon.
When a Ghostly Pokémon attacks, they have a chance of making the other Pokémon flinch. This ability is nullified by Shadow Pokémon..
Metallic and Ghostly abilities do not affect this type. IE: Metallics can be affected by status if the Shadow Pokémon has a status move. Shadow Pokémon won't flinch from Ghostly Pokémon.
Every attack that hits the opponent has 25% more power to it.
A Shiny Pokémon has 25% more HP. IE: A normal Pokémon has 400 HP but a Shiny Pokémon has 500 HP.
Unlike the others, there are all kinds of colors for shinies. Shiny Pikachu has its specific color, but as you look at something like Riolu, you can see a difference.
The ability of Mirage pokemon changes depending on the opponent's type. 20% more attack against Dark. Gains 20% HP against Shiny. Copies the ability of Ghostly and Metallic pokemon when fighting against them. Onfacing Shadow pokemon, it transfers all its ailments to the opponent (If your pokemon is poisoned, it heals itself and poisons the opponent). And finally Mirage Pokemon lose 10% health against normal pokemon.
These Pokemon have 50% more HP and 50% higher chance of critical hits.
