1. All-powerful, psychotic, and cosmic form of Jean Grey from the X-Men
2. To go insane with power
3. To become destructive and bloodthirsty
1. My favorite X-Men story is when Jean Grey became Dark Phoenix.
2. Now that he's the boss, he's turned into a total Dark Phoenix.
3. She ripped through that house like Dark Phoenix through the cosmos.
