When you equip a Nano in the appropriate group (a B Nano against C enemies), you'll gain a boost to your attacks, in addition to the nano's own special abilties. A is inherently stronger than B, B is stronger than C, and C is stronger than A. The enemies you face are divided into three groups, which were called A, B, and C when I played.

You can carry three at a time, and each one has three special abilities to choose from. Nanos are intrinsic to the combat system. In this case, there are 'Nanos.' When the evil green slime attacked, they managed to capture many iconic Cartoon Network characters, and created slime-based dopplegangers, dubbed 'Fusions.' Whenever you defeat a Fusion (your standard Boss fight), you're granted a Nano, which is essentially a mini-version of the character, that floats alongside you. Of course, a children's experience wouldn't really be complete without a whole mess of things to collect. You'll go to your guide (one of the major Cartoon Network characters) occasionally for missions and the like, and be rewarded with special equipment that only followers of your particular sect will have access to. Instead, you'll be choosing a 'Guide,' which works sort of like a profession trainer in World of Warcraft. You'll also be tasked with collecting equipment, armor, and weapons (both ranged and melee), which will change your character's appearance.

Most of the standard MMO tropes are here -– players can group together to beat quests, grind for currency and experience, and trade amongst themselves.
