Sebastian is a recurring character in Best Friends Whenever and he's also the main antagonist of Season 2.


Sebastian is a young arrogant Nobleman from 1522. Although they have never met, he and Daisy have been betrothed for two years. When Shelby and Cyd inform him that Daisy wishes to break their engagement, he will not release her from their arranged marriage easily.


He is egotistical and vain, and is a bully towards others. He is also misogynist.



He and Daisy had been betrothed for two years. In It's Not Ye, It's Me, he lost Daisy in a battle "to the death" with Shelby and Cyd (fortunately, Cyd spared his life).

Shelby & Cyd

When he had first met them in Daisy's time he was arm wrestling Cyd and later he and Shelby (dressed as a man) were fighting to the death until Cyd intervened and successfully defeated Sebastian while Shelby knocked him out



To be added.


  • He has a birthmark shaped like Italy.
  • He was betrothed to Daisy when he was fifteen and she was thirteen.
  • Sebastian's actor Barrett Carnahan also played Spencer on K.C. Undercover. Sebastian is similar to Spencer in that they're both arrogant bullies who make fun of the "new guy", who is really the main female character disguised as a man. Both end up fighting the disguised female character, and at the end, both characters find themselves schooled by a woman.
  • His actor also portrayed Link Evilman from the Nickelodeon series The Thundermans.
