“Stand back. Cuz once I reach my maximum size... I'll be LIVING LARGE!”
Capital G

Capital G is the size changing superhero of The Justice Friends.


Capital G is a tall man of presumably African-descent with a completely bald head and a blue mask which conceals his eyes. He wears a red jumpsuit with white and blue streaks across his chest and a large yellow "G" in the middle. He wears a golden necklace and a pair of blue and red sneakers.


He seems to be a very bold and serious hero with great confidence in his skills and never tries to show fear or disappointment even if things have gone horribly wrong for him.


Capital G has the ability to change the size of his body by growing or shrinking. He may have super-human strength and endurance, giving him invulnerability to some forms of damage and levels of strength depending on his size. He was one of the few heroes summoned by Rasslor to represent his planet shows that he is one of the most powerful heroes on Earth.


  • Super Strength - When at full size, Capital G possesses the might of a giant.
  • Flight: Capital G has shown the ability to fly at least twice and he can even fly through space. It is likely he can only use this under special circumstances.
  • Size Manipulation: Capital G has the power to freely change his size, able to shrink to the size of a tooth or to the size of a skyscraper. However, his growth is limited and his "Maximum Size" is only about half the size of Badaxtra.

Episode Appearances[]


  • Capital G is voiced by Greg Eagles, who would go on to voice the Grim Reaper from The Grim Adventures of Billy and Mandy and the fourth/incumbent actor to voice Aku Aku from the Crash Bandicoot games from 2007 onwards, which all three has a Jamaican accent.
  • He is likely a parody of Marvel's Black Goliath and Giant Man, and DC's Apache Chief, due to all three having size-expanding powers.
    • His design and color scheme, on the other hand, is likely based off the Harlem Globetrotters.
