The Zwerg Scandroid is a recruitable enemy found in Final Fantasy XIII-2. Its Monster Crystal can be acquired automatically in a tutorial battle in the main storyline, but unlike its partner in the battle, Cait Sith, it does not appear in normal battles in the Bresha Ruins, and can not be encountered again until Oerba 200 AF, two areas away from the Ruins.
The Zwerg Scandroid is one of the first two monsters that the player will tame, the other being the Cait Sith. Its ideal use is as an source of Sparkstrike for Infusion. As a Ravager, its stat growth is unimpressive; it will be very quickly superseded by other, more powerful Ravagers as the player progresses through the game. It only learns Lightning-elemental attacks. It can also be used to infuse Thunder when raised to level 8. Later in the game, Pleuston, which has Thunder at level 1, should be used instead.
Thunder has three advantages which Circuitron benefits from and therefore illustrates; it costs only one ATB segment, its damage is based on the magic stat, and is usable from range. Infusing Thunder can also add versatility to Monsters such as Blue Chocobo (wielding spells of two elements), as opposed to the strategy of covering all four elements with multiple monsters.
