I just noticed I forgot to give you the trivia for them before. Better late then never:
Shinx: -Shinx bears a resemblance to a hoax Pokémon that was created on April Fool's Day 2005. -Shinx's English name was originally thought to be "Spinx" because of a low quality photo with its name on it. -Shinx is the only Pokémon with a base stat total of 263.
Delcatty: -Delcatty and its pre-evolution are the only Pokémon that can obtain a Normal-type Hidden Power through their Ability Normalize. Not only that, they are the only ones who can have this permanently. -As of Generation V, Delcatty's EV Yield (1 HP, 1 Speed) is unique.
Zorua: -Zorua was first revealed with its evolved form, Zoroark, in the March 2010 issue of CoroCoro. -Zorua and Zoroark are the only two non-legendary Pokémon to be event-exclusive, discounting Rotom's alternate forms in Platinum, and Phione, whose legendary status is disputed.
Purrloin: -Purrloin was seen first in the Pokémon Sunday special episode preview in September 6. It was later removed from the same preview, much like the revelation of Zekrom's secondary type earlier. -Purrloin is the only Pokémon that has a base stat total of 281. -Purrloin has the lowest Attack stat of all Dark-type Pokémon.
