Underfeather/Chuck

Chuck is the older brother of Silver, the roommate of Bomb and a major character in Underfeather, who first appears in Finndin and continuously reappears throughout the game (At least in the Pacifist Route). His goal is to join the Mighty League by capturing a pig, and finally get more notice (and also get to get a shiny badge).

Appearance
Chuck is a short, perhaps biologically incorrectly shaped canary (Serinus canaria domestica). Being a species of 'Angry Bird', he has big eyebrows and also being optimistic, he usually grins a lot. He has a mainly yellow shade of feathers, with black tail and head feathers, and has orange feet.

Normal ("Ninja Costume")
For most of his in-game appearances, he wears his "Ninja Costume", which he obtained from a Rare Chest. It consists of a dark navy blue chestplate and navy blue underpants and a black scarf. A symbol that vaguely resembles the one of Papyrus's (The character he's based off of) is printed on his chestplate. There is also a sword and sheath attatched to the back of the costume that can be detatched. However, the sword is made out of plastic.

Befriending ("Battle Body")
Halfway during the date/hangout with him, Chuck switches to the secret costume that he wears underneath his ninja costume. He says that it is "Exotic", and was made for a costume party because he ran out of ideas Chuck says he got this off of a "Weird video game" (referring to Undertale).

Silver Date (Sup3r Sp33d)
During the "Date" with Silver, Chuck arrives with a costume reminiscent of ones worn in angry birds toons, with a sweatband, a scarf that is painted to look like fire and a chestplate reading "Sup3r Sp33d".

Birdsonality
Chuck is a charismatic and sociable bird who presents a confident and energetic view of himself. He works hard, and despite his arrogance, is kind of heart. He is optimistic and tries to persuade the pig even during the Genocide Route. He is also is shown to be reckless and unobservant at times, but is also shown to be smart and cunning, as shown when he tricks Red into befriending the Pig using reverse psychology. He is also shown to be overly protective of his sister, Silver, even claiming to break every single bone in Red's body (comedically) if he gets 'too close'.

He is shown to believe in others as much as he believes in himself. He had so much faith in his abilities that he waited outside of Eagle Mountain all night to be granted a position in the Mighty League. This caused Mighty Eagle to assign him to training with Red, (much to Red's annoyance). Instead, Red gave him cooking lessons.

He makes coconut dishes in his spare time, though many characters seem to think of it as not very good. One of these reasons is that he uses actual milk instead of coconut milk, as he learned from Red that it was 'rude to stare at another man's coconut' and couldn't take the pressure. He, therefore, cooks because everyone loves his cooking. He also loves puzzles and japes, as seen by the many 'ninja training courses' he prepares for the Pig when they arrive at Finndin. Chuck is also shown to be quite childish, taken to account the decoration of his room and other character's opinions.

Chuck is also very goofy and hyperactive at times, because he cannot control his speed. During many puzzles, he gets overly excited if the protagonist is making progress, and claims to have 'Gone totally beserk' when Red gave him Red Fruit juice to drink because there was a water shortage. He is not a typical 'angry bird', as he is only shown to get mildly annoyed at times when Bomb makes bad jokes. Despite his focus on getting into the Mighty League, he can be distracted and get off task quite a lot of times, such as leaving his puzzles to check his hair and the like.

Chuck is shown to be very prominent in battle, and uses a variety of tactical (but virtually harmless) ninja weapons in his fight.

Main Story
Some time before the events of Underfeather and the Angry Birds Movie, Red met Chuck and Bomb in an anger management class. Chuck was entered because he got into trouble with a police officer, as stated by both Bomb and Silver. After this, the Pigs invaded, and Chuck fought them alongside Red and Bomb and was deemed a hero. After the Birds' victory, he moved in with Bomb and Red when his sister Silver moved out, and after a while, Red also moved out to join the mighty league to help deal with the constant prank war going on. As a result, Chuck regularly visits Red and is close friends with Bomb.

Neutral Route
Chuck first appears in the Southern Snowdin forest, when he comes to check on his roommate, Bomb. After he discovers that Bomb hasn't reloaded the blue line slingshot in over eight days, he berates him and thus fails to notice the Pig hiding behind a pig cutout. He then starts a long monologue about his intentions to join the mighty league and get a shiny badge, but then gets annoyed that Bomb doesn't seem to understand fully. Bomb then makes some bad puns, causing Chuck to leave and telling Bomb to be on watch himself. Further on in the forest, Chuck meets the Pig for the first time, though confusing them for a piece of
