Special Traits (Japanese: 通り名Special Titles) are a game mechanic in the Pokémon Rumble series.
Early on in the game, Pokémon do not have Special Traits. After reaching Chapter 3 (in Pokémon Rumble Blast), there is a chance that a Pokémon will have a Trait when they are recruited. Each Pokémon has a chance of having any Trait, though some are more likely to have a specific Trait than others. In Pokémon Rumble World, the probability of a Pokémon having a Special Trait is boosted by buying and upgrading the Special Trait Tree.
Some Traits are marked with a "+" or "++" after their name; this makes them more potent, with ++ being even more potent than +. Rusty+ does not occur, and all cleansed Rusty Pokémon will have a Trait+ (or a multi-trait in Rumble World). No Pokémon with a Trait+ can be obtained until the player reaches rank 30 in Pokémon Rumble World.
When a Pokémon with a normal Special Trait (not + or ++) faints, it will have a green gear under it prior to Pokémon Rumble World. When a Pokémon with a Special Trait+ or ++ or a Rusty Pokémon faints, it will have a pink gear under it prior to Pokémon Rumble World. In Pokémon Rumble World, all Pokémon with a Special Trait have a gold circle around them instead of a blue one and emit gold sparkles instead of blue ones. Characters with multi-traits have a red circle and sparkles, with the exception of the Epic trait which has a purple circle and sparkles. In either multi-trait case (purple or red circle), the camera will temporarily focus on where the character dropped.
In the Switch Menu, the name and Special Trait of a Pokémon with a single Special Trait are colored pink; Pokémon with multiple Special Traits, or those obtained by password, have theirs colored blue. Also, Rusty Pokémon will have their name colored brown, and Epic Pokémon will have their name colored purple.

Occurrence on Pokémon species
Some Traits are only found on certain Pokémon, or are simply more likely to be found on certain Pokémon than others. Most are based on the Pokémon's Ability in core series games.
Certain species, Mega Evolutions, and Primal Reversions have their own unique Traits. These are innate to the Pokémon in question, but are not directly shown like other Traits, allowing them to have any other standard Trait.
Desolate Land: Pokémon with this Trait are completely unaffected by Water-type attacks. This effect does not apply to enemies or allies. Exclusive to Primal Groudon.
Primordial Sea: Pokémon with this Trait are completely unaffected by Fire-type attacks. This effect does not apply to enemies or allies. Exclusive to Primal Kyogre.
Slow Start: Attack and Speed are halved until this Pokémon has defeated 10 Pokémon on the floor. Exclusive to Regigigas.
Wonder Guard: Attacks that would not be super effective against a Pokémon with this Trait will usually, but not always, deal no damage. Any secondary effects may still occur. Exclusive to Shedinja.
Trivia
In Pokémon Rumble World, one of the loading screen 'hints' states that it is possible to obtain Pokémon with traits that have three or four pluses. However, it is not possible to obtain these Pokémon through gameplay, and if such a Pokémon gets edited in, the game will freeze when its summary is viewed.
