I'm trying to remember the name of an anime I watched back in the mid 2000, it was possibly made in the 90s.
The premise from what I remember was post-apocalyptic world where planet Earth has been completely destroyed and now people live on other planets. There are these 7 or 8 special marbles/gems that give their user super powers/special abilities. Also these marbles/gems if collected and used together can bring back planet Earth.
There is one particular character that had white hair about ear length and used the green coloured marble/gem which was placed in his eye socket.
