Stitch in the Cosmos Bragg and Twang

As promised, here's more info about Twang's past as well as revealing vis rival.

Bragg – Also known as Experiment 145, she is very, well, braggy and conceited, not caring about others except for her own personal gain. Similarly to Twang, after being found a "tame" experiment, Bragg was offered a job as a recon officer. She immediately accepted, enjoying the idea of getting fame and glory. Bragg soon found out that it was harder then she thought and started to become jealous of her "twin", Twang, because of how quickly ve ascended the ranks. In an attempt to get Twang "accidentally" killed, she suggested to the leader of the relations diplomatic team to send vim to the Intergalactic Mafia base. However, Bragg became frustrated when ve started to and from the base, so she decided to follow vim, only to discover that ve was meeting Amalgamate. Seeing this as the perfect opportunity to get rid of Twang, she reported the event to the diplomatic team leader, labelling it "an act of treason punishable by death". Once more, Bragg became frustrated with Twang's ability to survive so well, but, this time, she slipped up by accidentally admitted that she had tried to sabotage Twang multiple times. When the diplomatic team leader found out about this, the leader had her stripped of the rank she had earned and put her on probation for a year. Now that she's off probation, Bragg is hunting down the one that she views as the one who made her lose job as well as the one that she has declared her rival: Twang.

Twang – Also known as Experiment 021, ve is very meek, quiet and doesn't accept praise easily due to noticing how people acted/reacted to either receiving praise/seeing other get praise. After being discovered as an intelligent and "tame" experiment, Twang was offered a job at the Galactic Federation as a relations diplomat. Seeing as ve had no other choices, ve accepted and soon climbed the ranks due to vis strengths at being very calming and persuasive. After a year or two into vis career, Twang was assigned to make contact with the Intergalactic Mafia, which was rumored to be run by a very powerful experiment. So, doing vis job, ve arrived at the Mafia's headquarters... only to meet a very attractive 600-series experiment who just so happened to be the leader of the Mafia: Experiment 621, also known as Amalgamate. To say the least, Twang fell for Amalgamate the moment ve saw xem. So, ve kept on visiting Amalgamate, kind of forgetting this was an enemy of the Galatic Armada. And, it went on for months until Bragg caught vem in the act. She threatened to tell everyone about vis "affair" with Amalgamate. When Twang refused, Bragg exposed their relationship to everyone and, unsurprisingly, ve was almost arrested. Notice the word "almost". Ve managed to evade capture and sought refuge with Amalgamate. And they've been together, evading the police ever since. Twang's main rival/antagonist is Bragg.

As a note, the reason why the two are "twins" is because, after Twang was created, Jumba decided to use a similar design to make Bragg, making them look extremely alike.
