CENTINEL-Suits are special battle suits worn by the Wonderful Ones.
When they transform, they change into a reinforced outfit called a “CENTINEL-Suit.” This suit was developed at the CENTINELS Central Science Laboratory. 40 years of warfare with the invaders have brought one improvement after another to this suit, and it continues to evolve even now.
The suit that is currently in use is the 3rd Generation model, which sports the “Unlimited Form,” a special armed form that allows the wearer to temporarily remove the limiter in cases of emergency. As a special battle garment, it only takes "three billionths of a second", stated by Laurence Nelson, to transform into the CENTINEL-Suit.
Unite Morph allows you to materialize certain objects by combining your teammates. The object data required to unite is recorded in each suit, the more members that join to your aid, the bigger the object will be. The basis of Unite Morphs lies in formation.
In gameplay, drawing various shapes will create different types of Morphs that you can use to create weapons, or bridges and other useful tools. Such as a Glider, Bridge, and ladder. Creating Bridges and Ladders is know as the "Wonder-Liner". By using the Wonder-Liner, it allows you to form your team into a straight line, and it's primary use is to overcome obstacles. It also has a secondary use, such as finding secret areas. Sending a Wonder-Liner into a Wonder-Toilet will unlock a special item, but only if enough are sent it, which will be signified by the top bursting open, and a sound.
There are, however, limitations to both the CENTINELS suits and the Unite Morphs. Once the wearer of the CENITNEL suit comes close to a full impact with his or her body towards an enemy, his or her CENITNEL suit may automatically disappear or become damaged. This goes to the example of the Unite Gun. This also comes with the combat against enemies or obstacles with different types of fighting mechanics (e.g., spikes, faster speed), where several of the Unite Morphs are not affective.
