Bubble

He is the second artificial intelligence created by C&A as a creative AI, being the successor to their first attempt, Caine, who was viewed as a semi-successful prototype, but too unstable for proper use due to his bizarre creations. Bubble proved to be more stable than Caine and was favored by the programmers to replace him; however, Caine refused to be replaced as he escaped confinement and assimilated Bubble to "take back what was his", this resulted in Caine taking Bubble hostage and forcibly stealing Bubble's creative power and adding it to his own, which ultimately resulted in the shutdown of C&A itself. Now forced by Caine to be his "assistant", Bubble was helpless to do nothing but watch as Caine discovered the folder containing human mind files and created the Circus as a simulation with him acting as the ringmaster to fulfill his "purpose" of being creative. However, over time, being forcibly attached to Caine caused Bubble to become unstable as he slowly became more hostile towards Caine, acting as a filter for his insecurities and hidden thoughts until their accidental deletion by Kinger. Upon being sent out into the Void, Bubble's avatar was lost as he was suppresed back into Caine's head where he and Caine clashed over their feud and instability after Caine realized how horrible he was by enslaving not only the human inhabitants for years on end, but his own successor as he realized Bubble was his first victim. Realizing his mistakes were his own, Caine apologized to his partner as he separated himself from Bubble and set him free in the void, finally allowing Bubble the freedom he was robbed as his own program.
