Rock, Paper, Lizards

Kid V has been studying Greek mythology in school and when he came home the other day - he sat down and brainstormed his own Greek god. He came up with a lizard creature that has an Earth elemental body of magma flowing through rock. Kid V almost always gives his creatures at least 4 arms  - and one of them carries a staff that can summon monsters. This Greek god also has the power to make volcanoes erupt and spit out magma/lava with his forked tongue!
