Jar

Jar is a host throughout the Roleplay Rumble series in both Roboty's Roleplay Rumble, RRR: Monotopia Beta, and RRR: Monotopia.

Personality
Jar is a very sardonic and pessimistic person, but also selfless and caring towards those she cares for. He is very mellow and chill, sometimes even downright apathetic, showing little emotion and he makes sure to remain distant from most others. However, there are times where she does open herself up, mainly towards her rival-turned-best-friend, Box. He is typically a kind presence, but due to his blunt and reserved nature she can easily come off as rude.

Roboty
Roboty and Jar were originally shown to have a very one sided friendship. Jar seemed to detest Roboty while Roboty viewed her positively - possibly his only relationship like this. After a few episodes of RRR he was officially made a co-host by Roboty with their dynamic remaining static.

However, things took a turn after Roboty was crushed by Pillar. Jar, due to her relationship with Roboty, knowingly avoided recovering him and instead hosted the show by herself. However, once Roboty was recovered by Box, his toxicity in his dynamic with Jar was made apparent as he immediately attempted to turn others against her. Although, once Jar came back after the volcano eruption, they made up and seemed to be on better terms.

As the show neared its end, their relationship began to deteriorate. After Box and Roboty got into an argument that led to Box leaving the show, Jar began to reflect on his own relationship with Roboty and he soon realized how downright cruel Roboty was towards him. This led to Jar leaving the show with Box and the permanent end of his friendship with Roboty.

Right before the impending war began, Jar and Box returned to help the rebellion fight against Roboty. Jar was careful about avoiding Roboty's clones and even Roboty. Unfortunately however, Box was killed during the battle. After a talk with some of the other rebellion members (primarily Trans Flag and Goldfish) led to Jar feeling even more motivated to defeat Roboty. As the battle reached it's end in space, Jar helped protected everyone and gave Monokuma the chip to kill Roboty, leading to Jar's former friend and arch-rival's demise.
