Amadioha is the powerful deity (or Árúsí) of thunder and lightning in the traditional religion of the Igbo people of southeastern Nigeria.

His primary roles and associations are:

1. Justice and Vengeance: He is first and foremost a god of divine justice. He speaks through thunder and strikes with lightning to punish evildoers, avenge the oppressed, and enforce moral and societal laws. Oaths are often sworn in his name, with a broken oath incurring his deadly wrath.
2. The Sky: He is sometimes referred to as Igwe (sky) and is considered the “Owner of the Sky.” He is often depicted as the enforcer of the laws established by Ani (or Ala), the Earth Goddess.
3. Love, Peace, and Unity: In some traditions, he is also invoked for benevolence, prosperity, and the collective will of the people.
4. War: He is a warrior deity, often invoked for protection and victory in times of conflict.

His symbols are typically a white ram (a common sacrificial animal for him) and the color red. He is often compared to other thunder deities like Shango of the Yoruba people.
