Retainer is a male character who competed in Open Source Objects.
Due to his lisp and a history of unfortunate interactions, Retainer's used to people ignoring him and talking over him, and often assumes ill intent (against himself in particular) even when there's none. He tries to remedy these issues by being vocal, and actively talking over others to make himself heard. Rude to those who he believes slighted him, he can veer into inconsiderate and impatient, and often isolates himself and cuts off ties with people.
Retainer is a pink retainer with a grey, metal rod of sorts around him. He is armless.
Episode 1 - "Who the hell recommended Glowing Heart"
Retainer first appears in the challenge, with three balloons tied onto his rod. He impatiently awaits Roulette Wheel's solution to the challenge, speaking simultaneously with Coin. Too alongside Coin, he realizes that getting down while being armless would prove difficult. He fails to get Organic Fruit & Grain Bar's assistance, and he later finds similar unhelpfulness from OSO Novel. After silently arguing with Coin, White Dango chomps Retainer's balloons, making him land safely.
Episode 2 - "Your Opinion is Invalid"
Retainer pairs up with Roulette Wheel for the stacking challenge. Nail Clippers attempts to pair up with him, but he rejects her due to what she did to Incense Holder in the last episode. Retainer does not fall off of Roulette Wheel, making the pair safe from elimination.
