Chronians are a species from the planet Chronia.
The Chronians were planning to conquer Earth, the Chronians were freed when Eon used the Hands of Armageddon to open a time rift between Earth and Chronia, but the Chronian invasion was sent back when Max deactivated the Hands.
Chronians are able to manipulate time at its base level, allowing them to accelerate, reverse, or halt the progression of time in their immediate vicinity. They can backfire on them if their powers weakens Chronians and speeds up their aging process.
The name "Chronian" comes from the name "Chronos", the name of the Primordial God of time from Greek and Roman mythologies.
