machina maw

Machina Maw is Rikku's special dressphere. It's made of three parts: Rikku, Crusher-L and Smasher-R (or Crusher-R and Smasher-L). It's specialized in physical attacks, and with the right stragedy it's supposedly a real killer.

Description: Special Dressphere harnessing the power of machina. Rock and roll with Break Missile or crush your competition with Vajra. It's smashing, baby!

Acquire: Part of the storyline. Find on the Oasis while liberating LeBlanc Syndicate's uniforms.

Opinion: Everyone keeps saying what a killer Machina Maw is. I'm not really into these special dresses anyway, but I haven't killed a thing with it. Yet. It's big and nasty-looking and has the right abilities, but I don't know...

Mascot

The mascot dressphere is special, because all the girls have different abilities like with the trainer outfit. And you have to obtain an EPISODE COMPLETE at every corner of Spira in order to acquire it.
Rikku's mascot is the Cait Sith and the attacks are more status based. She can have fun with poison and berserk and zombie and all the fun stuff.

Description: I don't have the dress myself, so I can't get the description from the game! *wail*

Acquire: On chapter 5 get an "Episode Complete!" on all areas of Spira, then go to the Celsius, do some stuff (still a bit fuzzy on what stuff) and the dress is yours!

Opinion: I haven't got hold of this one yet, but it's supposedly one of the best dresspheres. I'd like to see it one day...

thief

Thief is Rikku's default dressphere, and quite useful for being a default.

Description: Attack with speed. Stop fiends in their tracks with Borrowed time or help the party hightail it out of battle with Flee. You'll steal the show in no time!

Ability Description
Attack basic attack
Steal steal item from enemy
Pilfer Gil steal gil from enemy
Pilfer HP steal HP
Pilfer MP steal MP
Borrowed Time cast stop on one enemy
Sticky Fingers always steal items from one enemy
Master Thief steal rare items
Soul Swipe cast berserk
Steal Will one enemy flees from battle
Flee party escaped from battle
Item Hunter icreases number of items dropped by fiends
First Strike strike before the enemy
Initiative raises party's luck striking first
Slowproof protection against slow
Stopproof protection against stop

Thief steals just about anything, helps the party from tough battles with Flee and lots more. Although the dressphere concentrates on agility, it's strength, defence and magic defence are still on the better side. It's not very strong but neither is it weak.
