|“||When mortals meet me, they call me... the Grandmaster! When we part, they call me... sorrow!||„|
Grandmaster is an extremely sadistic and manipulative individual. Best known for his obsession to manipulate life forms into playing his games on life and death, Grandmaster is rarely pure sadistic mastermind as he enjoys of creating games and to watch the "players" die or fighting for death.
In addition, Grandmaster is a highly intelligent and ruthless individual, as he is enjoying from attempting killing or just killing life forms without remorse. More than that, Grandmaster is also a pure megalomaniac as he gloats about the vast power that he has in the games. Also, he is a tyrannical and pure evil individual as he obsessed with conquering the universe and controlling his games with an iron fist.
In addition to his chaotic and evil personality, Grandmaster is an extremely childish being as he just enjoys from making games of life and death just like as a 6 year old boy enjoys of playing in action figures.
Grandmaster was part of the Elders of the Universe - godlike beings that represented the eldest species of the universe, they were also largely sole survivors of their respective species and had cosmic powers comparable to beings such as the Watcher.
Like all Elders Of The Universe the Grandmaster is kept immortal only due to his fixation on a particular subject: in his case games of chance - if he should lose interest in his obsession he would weaken and die, he alongside a number of his fellow Elders attempted to kill Galactus at one point, theorizing that in his death they would be reborn as gods in the new universe (despite already having semi-godlike powers): their plan was foiled by the Silver Surfer and several other heroes.
