Elementals

The Elementals are a group of evil masks who have the power to manipulate a particular element and cause chaos across the world. Their only appearence is in Crash Bandicoot: The Wrath of Cortex where they gave Crunch powerful abilities. They are only able to be imprisoned if you have five Elemental Crystals. Dr Neo Cortex used them as a power source for Crunch when he was brain washed and still evil.

Quick to anger with a head full of rocks and grumpy, Rok-Ko is the Elemental mask of Earth. He controls such earthly forces as earthquakes and landslides to name a few. He seems to be the most childish of all the elementals, giving juvenile fight threats to Crash Bandicoot. The only witnessed powers he possesses are causing rocks to fall from the sky and protecting Crunch with a rock sphere

Wa-Wa

Out to flush the world clean and rebuild it as he remembers it, this stick-in-the-mud puddle is the Elemental of Water. He has a militaristic personality, and has a typical american general's accent. His powers (as seen) include transforming crunch into suspended water, and creating balls of ice. He can also bestow the ability to create energy waves.

Py-Ro
Voiced by: Mark Hamill/Toshitaka Shimizu (Japan)

The strongest and the most evil of the ancient Elemental masks, Py-Ro controls the element of Fire. His temper is known to go off like a volcano when pertubed. He has a somewhat calm personality, that is somewhat insane. He, as expected, has an affinity with fire. He can conjure fire, from the ground or as a wall, and transforms crunch into a load of smouldering rocks in his form.

Lo-Lo
Voiced by: Jess Harnell/Masaru Ikeda (Japan)

This crazy joker could be a real blast at a party if he didn't always blow the house down! Lo-Lo is the Elemental of Air, and has dominion over the the forces of wind, lightning and atmosphere. He can create electricity at will, and can transform crunch into a huge, genie-like entity that can throw electricity. He has a somewhat effeminate personality, and is quite arrogent.

 * They share the one game only trait with Von Clutch, Rusty Walrus, Zem, & Zam
 * Out of all of past villians, They never came to Dr. Neo Cortex's "little gathering" (which he calls a birthday party) in Crash Twinsanity. The others being Rilla Roo, The Komodo Brothers, Zem, & Zam, Though this is probably because they were imprisoned in The wrath of cortex

History
Like Aku Aku and Uka Uka, the Elementals were probably powerful witch doctors many years ago who put their spirits into magical masks when they died. They may or may not be brothers. It is unknown if they are related to Aku Aku and Uka Uka in any way.
