Surprise

Surprise is a Pegasus pony and a member of the aerial acrobatics group, the Wonderbolts. She first appears in The Ticket Master. She is not named in the show, but she is named in merchandise.

Design
Surprise has the same coat and mane colors as Lauren Faust's concept art of Pinkie Pie based on a G1 Pegasus mare also named Surprise, as a female Pegasus from the IDW comics' who appears in a flashback as a filly resembling G1 Baby Surprise and as Pegasus mare Breezie from the fifth wave of mystery pack toys and collector cards. Surprise also shares her mane and tail style with "Blaze".

Depiction in the series
Surprise first appears in Rainbow Dash's imagination in The Ticket Master alongside Soarin and "Blaze". Rainbow imagines herself impressing the Wonderbolts that they let her join. She later appears in The Best Night Ever, once again in Rainbow Dash's fantasy of flying with the Wonderbolts as well as in the Wonderbolts' VIP section at the Grand Galloping Gala.

Surprise, with her mane a darker shade of yellow, appears as one of the Pegasi fighting against a monstrous Spike in Secret of My Excess, alongside "Blaze" and "High Winds". Spike traps her and her fellow Wonderbolts inside a water tower. Near the end of the episode, when they're finally freed, Surprise trembles with fear before striking a heroic pose and flying off with "Blaze" and "High Winds".

Surprise later appears with her usual mane color in Rainbow Falls, watching the Cloudsdale cheerleaders.

Depiction in the comics
Surprise appears in the IDW comics', on pages 18 and 19.

Merchandise
A miniature collectible of Surprise, called simply "Wonder Bolts pony", is included in the Cloudsdale Set with Rainbow Dash and Gilda the Griffon. A list of Wonderbolts on page 34 of Little, Brown's My Little Pony Friendship is Magic official guidebook My Little Pony: The Elements of Harmony includes the name "Surprise" without specifying Surprise's identity. She is identified on her Enterplay collectible card game card α #50 R, which gives her the description "One of the more elusive members of the Wonderbolts, Surprise has never been seen in public without her uniform on. Her teammates all say she is an absolute blast to hang out with."
