DO NOT READ IF YOU DONT WANT SPOILERS FOR GOLDS ADVENTURE!!!! In the first episode, the gray guy called Gold "Calamity" because they are both Chaos Sprites. But, Inside of golds body is the chaos sprite named Calamity. He is the personification of chaos. Calamity has a tight hold on his body and has no intention of leaving. Eventually gold will have to face Calamity in his own mind. It will be a chaotic battle and could escape his head and go into the real world.

tel l me what yall think.....im trying to make my lore better... Calamity can talk to gold but chooses not to as he sees gold as Unworthy for inhabiting his soul. He didnt choose gold as a host; the Chaos itself punished him to, in his words, "That bumbling idiots head. Have fun with his idiotic thoughts, traitor". Eventually their relationship will better but its mostly one sided. Calamity tries multiple times to escape, but he simply can't; gold is too powerful in the Chaos force. Not even the Chaos knew he was this strong. Eventually he even surprasses the chaos itself.
