Trikon

The Trikon were originally a trio of Alpha Primitives who were granted "near-human" intelligence by Maximus while he was imprisoned in Attilan in the mid-20th century. Maximus hoped to foment a rebellion among the Alpha Primitives on the way to ousting his brother, King Black Bolt, and claiming the throne for himself. The three Alphas exposed themselves to the Terrigen Mist and transformed into three floating balls of raw energy, calling themselves the Trikon. They led the Alphas in wreaking havoc throughout the city and freeing Maximus, allowing him to usurp Black Bolt's crown. During the battle against the rest of the Inhuman Royal Family, the Trikon blasted Medusa with an energy beam, sending her sky-sled falling from the sky and hard to the ground, inflicting her with amnesia. Black Bolt and Lockjaw teamed up to defeat the Trikon, as Lockjaw opened a portal to the Negative Zone and Black Bolt sent them through it with a whisper. As they went plummeting into the alien dimension, the Trikon vowed revenge against the Inhumans.
