Angel, or Angel Bunny, is a male rabbit and Fluttershy's pet. He is somewhat spoiled and bossy towards Fluttershy on occasion; however, he does care about her and actually displays an intention to help her stand up for herself. Most of Angel's actions are played simultaneously with instrumental jingles.
Angel is first introduced in The Ticket Master, where he snatches the tickets to the Grand Galloping Gala away from Spike and gives them to Fluttershy. When Fluttershy is too shy to explain why she wants to attend the Gala, Angel thumps her hoof with his hind leg impatiently, making her explain herself. He later appears in Golden Oak Library, making a salad for Twilight Sparkle while Fluttershy cleans and tidies, in order to persuade Twilight to give the extra ticket to Fluttershy. She tries to tell Twilight that she was cleaning up because they were good friends, before turning to her rabbit friend, whose stern look reminds her of the original intent of providing a special favor in order to receive a ticket.
In Dragonshy, Angel is seen in the opening happily eating a carrot until Fluttershy comes about and warns him to not eat too fast. He then refuses to eat at all and later shows Fluttershy a big black cloud in the distance. Later, when Spike announces that he will look after Fluttershy's animal friends, Angel hops on Spike's head and stomps furiously. This causes Spike to flinch and have all the animals around him scurry away. At the end of the episode, Spike catches Angel just to drop him on his head to make a note to Princess Celestia.
In the beginning of A Bird in the Hoof, he reminds Fluttershy to go to Princess Celestia's welcome party until she remembers and then convinces her to go despite her nervousness. The scene makes a reference to the White Rabbit from Alice in Wonderland, with Angel apparently possessing a pocket watch that he uses for calling Fluttershy's attention to the time. Fluttershy then quotes the White Rabbit from Disney's Alice in Wonderland saying that she's "late for a very important date." After Fluttershy repeatedly thanks Angel for reminding her, he shoos her outside every time she returns to thank him, even going so far as to lock her outside.
Angel is one of the bunnies who get their legs elongated in The Return of Harmony Part 2, and when the rabbits stampede over Twilight Sparkle, the corrupted Fluttershy congratulates him and says that she's very proud.

In Putting Your Hoof Down, Angel has a much more spoiled and short-tempered personality. He is shown to be very picky, wanting a salad perfect to the last detail instead of the carrot salad given to him. At the end of the episode, Angel still refuses to eat the plain carrot salad Fluttershy had previously given to him and throws a small tantrum when the now assertive Fluttershy doesn't give in to his demands as she normally does. Instead, Fluttershy uses the "Stare" on Angel, who immediately calms down and reluctantly proceeds to taste a slice of cucumber. He finds the taste to his liking and rapidly devours the bowl's contents.
From Hurricane Fluttershy onwards, he returns to his much more sympathetic and supportive attitude towards Fluttershy. In the aforementioned episode, he comforts her after she runs away from training and oversees her own personal training as her coach.

In Just for Sidekicks, Fluttershy asks Spike to petsit for her in exchange for a large jewel. Neither Spike nor Angel is happy with the arrangement, but the former goes along with it anyway. Angel is apparently fond of having his tail fluffed a certain way, and doesn't trust Spike to get it done, spending the whole episode with his tail in curlers. He also shows genuine affection for Fluttershy, nuzzling up against her as the girls are saying their farewells. He spends much of the episode tormenting Spike, running away from him constantly, and eventually ending up on a train to the Crystal Empire. Angel tries to reunite with Fluttershy as they're boarding the train for home, but Spike recaptures him. He then attempts to blow their cover when they're trying to hide, but changes his mind when Spike admits his faults in neglecting the pets throughout the episode, and even finally getting his tail fluffed. Angel even retrieves Spike's last gem and feeds half of it to him so that his growling stomach doesn't give away their hiding spot.
