Coiny [LeafCoin]

BFDI Although Coiny is nice sometimes, he is relatively rude when someone messes with him. In addition, he occasionally has conflicts when others sabotaging him. The most notable of which is with Firey. During the first season, he used to have an intense hatred toward him when the two frequently slapped each other in episodes. This was because Coiny forgot about Firey's poison, water.

Coiny has also shown an ability of persuasion and charisma. He generally tries to give speeches toward the other contestants on several accounts throughout the series, and he was even able to convince Firey to let him into Dream Island.

BFDIA Coiny now has many more rude and abrasive moments than before with some of the contestants (not too much) who aren't his friends, such as Teardrop, Bomby, and Spongy. He is also more of a leader and a strategist coming up with ideas to help his team and Pin. For example, he convinced her to switch teams and used his teammates' abilities to benefit them in certain challenges. Initially, Coiny is somewhat callous and unfriendly—in "No More Snow!", he is unconcerned by the prospect of Spongy, Needle, and even Pin being dead forever since it increases his chances of winning. He also forces several contestants to switch to his team by threatening them.

However, as the season progresses, Coiny matures and mellows out. In the latter half, he becomes a voice of reason for the more aggressive Pin, frequently checking on her well-being and trying to calm her down when she's upset, like when she’s frustrated at Ruby stealing her song in "PointyPointyPointy ♫". Additionally, in the same episode, Coiny expresses frustration when Pin is the target of jokes and takes action to support her, such as spinning the prize wheel on her behalf to ensure she receives a favorable outcome. This emphasizes Coiny's loyalty and protective nature, especially towards Pin. He works closely with her to complete the challenges, and his willingness to assist in fixing her mech suit shows his commitment to teamwork.

After Pin leaves him behind to win the contest for herself in "Airplanes in the Night Sky", Coiny is apparently unbothered. However, it gradually becomes clear that he was in fact affected. In the following episodes, Coiny is concerned only with having fun, brushing off any hardships or hostilities and not taking anything very seriously. But this attitude becomes less convincing as the challenge goes on, and it is heavily implied that he is only focusing on having fun so as to suppress his true feelings. He decides to make Pin lose even if it means losing himself, and defends his choice by saying that she doesn't care about all the help he gave her, so he is trying to have fun instead of focusing on the contest.

IDFB Coiny is shown to be somewhat childish and energetic. This is shown in "Welcome Back," where he yells that the grotatoes will taste delicious and tries to eat them when they've barely began growing. He also hypes up the wall teleporter calling it his "favorite thing in the whole world" despite not knowing what it is. Finally, in the stinger ending of the episode, he gleefully takes "deep-fried breaths" with boiling frying oil, much to Fries' and Leafy's terror.

BFB Coiny is nicer and also much more thoughtful. Some examples of this are shown when he comforts Pin in "Four Goes Too Far" and offers Marker some dirt cake in "This Episode Is About Basketball". He also seems to have grown closer to Firey over this time.

TPOT Coiny showcases his ability to think creatively and utilize the strengths of his teammates to achieve the team's goal, such as in "You Know Those Buttons Don't Do Anything, Right?" when Coiny uses Pin to climb the building. This also influences the strategy of the other team members, indicating that Coiny's actions can have a broader impact on the team.

He also appears to be strongly attached to how things used to be, particularly regarding his relationship with Pin during their time in BFDIA. In "The Worst Day of Black Hole's Life", when Pin expresses discomfort with using glue in this challenge and shares her dislike for that season, it likely clashed with everything Coiny remembers: an era filled with memories that he looks back on with pride and nostalgia. This leaves him confused and questioning this unexpected side of Pin, since she liked to win in BFDIA.

Your Leafy, and Coiny tries flirting with you.
