Aetna is a destructive angry robot lady. She is 18 feet tall and the sister of Ionia. She was built by Medusa and Pulsar. Her destructive rages led her to be shunned by the peace-loving Hallas faction. She has her own faction known as 'Aetna's Disciples'. A little humour based on the fact that local orthodox priests used to yell religious things at her. Moody, brooding, angry. Has internal furnaces and fire cannons. Has chimneys on her head that belch smoke.
