Summary
Cait Sith will be the last playable character to join the party inFinal Fantasy 7 Rebirth. He won’t be the last of the main cast to join though, as Cid and Vincent are in the game too. Visually, Cait Sith has changed from the original game, as he mostly runs around in his cat form now.
Cait Sith still uses Megaphones inFinal Fantasy 7 Rebirthand the Moogle he rode constantly before is now a summon in battle. Now, eachMegaphone weapon inFinal Fantasy 7 Rebirthhas an ability attached, this is how they compare to each other..

For those sensitive to spoilers, some of these entries may reveal the location of Cait Sith’s weapon.
7Roll O’ The Dice (Yellow Megaphone)
Roll Them Bones And Inflict Damage
Cait Sith will start with two Megaphone weapons when he joins the party inChapter 9 ofFinal Fantasy 7 Rebirth. His standardized one, theYellow Megaphone, is like his Buster Sword. It will give him the Roll o’ the Dice ability to use in battle.
Roll o’ the Diceis like a retooled version of one of Cait Sith’s Limit Breaks from the original game. Cait Sith will toss dice and damage will depend on what numbers they land on. Sometimes the attack can be devastating and other times it can fall flat.

6Fortune Telling (Iron Megaphone)
Perform A Random Attack
TheIron Megaphoneis the other default starting weapon for Cait Sith. With it, he can learnFortune Telling, which produces a random effect during battle. Most of the effects are based on damage, so it plays similarly to Roll o’ the Dice just a bit more flashy.
Fortune Telling is slightly the better of the two attacks, although they are both based on luck. They both function better than the randomness Cait Sith produced in the original game, which is a nicegameplay change forFinal Fantasy 7 Rebirth.

5Lady Luck (Gjallarhorn)
Land A Critical Attack Easily
In theNibel region ofFinal Fantasy 7 Rebirth, players can find the Chocobo Sage to get their aquatic Chocobo. Later, he will give players a side quest called Esoteric Secrets of the Elders which involves getting tufts of Chocograss. If players get 45 tufts of Chocograss, then the Chocobo Sage will reward them with theGjallarhornweapon for Cait Sith.
Gjallarhorn will teach himLady Luckwhich is a party-based buff ability. This will increase everyone’s critical hit rating, meaning that it will be easiest for characters to land a critical attack for a lot of damage. It’s Cait Sith’s only support ability.

4Moogle Kaboom (Red Megaphone)
Turn Moogles Into Living Bombs
Cait Sith will always enter battles as just the cat version of himself. Once a single ATB bar is filled, players can summon a giant Moogle for Cait Sith to ride. Even after summoning it, Cait Sith can hop off and the Moogle will act on its own accord, sort of like a decoy.
With theRed Megaphoneweapon, acquired in Gongaga Village, players can learnMoogle Kaboom. This will turn the Moogle into a ticking time bomb that will explode upon impact. Players can summon a replacement Moogle during the same battle, so it’s not a big dealfor Cait Sith.

3Moogle Mine (Resounding Megaphone)
Launch A Bunch Of Mines To Stagger Enemies
There are actually two Megaphones that players can obtain in the Gongaga region. The second is in the Gongaga Airstrip, called theResounding Megaphone, which is where playerscan meet Cidfor the first time.
It will teach Cait Sith theMoogle Mineability, which will randomly launch a bunch of mines around the battlefield. Enemies that step on a mine will have their Stagger meter increased as they take on damage too. Cait Sith must be riding the Moogle to use this ability.

2Moogle Magic (Crystal Megaphone)
A Secret Way To Summon
TheCrystal Megaphonecan be obtained in the Cosmo Canyon region. It has theMoogle Magicability attached to it, which Cait Sith also needs to be on a Moogle for this one. It will use a Summon ability at random, depending on the Summon Materia equipped by Cait Sith.
For example, withthe Summon Shiva, Cait Sith can use Heavenly Strike or Icicle Impact. Cait Sith can use Moogle Magic multiple times in battle, but every time he does, there will be a longer cooldown time, since these Summon abilities are very strong.

1Moogle Knuckle (Golden Megaphone)
A Simple But Impactful Punch
Cait Sith’s final weapon, theGolden Megaphone, can be obtained in the Shinra Mansion. It can be unlocked during the mission wherein he leads Barret and Aerith around the vicinity. It will teach Cait Sith theMoogle Knuckleability, which is another one that requires him to be riding the Moogle.
Moogle Knuckle is a simple punch attack that is less flashy than Cait Sith’s other moves, but the impact this punch has on enemies will be critical, and it can Stagger them too. Captain Falcon would assuredly be jealous of this punch and Cait Sith would fit into theSuper Smash Bros.universe rather well. He’s certainly a better fit than the gloomy loner that is Cloud, who did get intoSuper Smash Bros. Ultimate.
