Lava Barf Eruptor
. The name itself gives you an excellent idea of exactly what to expect from this cute little clump of flames. It looks like it's the child of Mt. Krakatoa and it vomits molten rock. This little guy isn't just packed with attitude: he's built purely for offense, with a skill tree that features absolutely no passive abilities whatsoever. If you're simply out to cause as much pain to the forces of Kaos, this one might be your go-to Skylander.
Lava Barf Eruptor's primary damage-per-second attack is the Lava Blob, a simple projectile attack that has the fiery gremlin hurl chunks of liquid death wherever you aim them. As you level him up and purchase upgrades, these blobs increase in size, speed, power, and even number. This ability's growth tree culminates in an ability that has the hilariously campy name of Lava Blob 2: Barf Harder. Using this ability has Lava Barf Eruptor eat the blobs and regurgitate them. Naturally, this hurts much, much more.
Though Lava Blob (and its "sequel") may be your default weapons, you'll inevitably be using Lava Barf Eruptor's area-of-effect attack, the Eruptor. This attack is truer to the Skylander's namesake, as it immediately results in a pool of lava barf that is several times his size. Upgrading this ability results in a stunning display of pyrotechnics called Revenge of Prometheus, which adds the sudden appearance and eruption of several tiny volcanoes.
