Green Ghost

Green Ghost in Invincible refers to two different characters: the original male hero who was an original Guardian of the Globe and was killed by Omni-Man, and the current female hero (voiced by Sonequa Martin-Green) who took up the mantle and is also part of the team in the animated series, capable of intangibility and flight. The animated show introduced the female version first, leading to some initial confusion about the legacy, with the original male Green Ghost being a prominent member of the first Guardians of the Globe.
