Sera is a minor character from the 1985 animated series She-Ra: Princess of Power.
She-Ra: Princess of Power
When her teacher Serena was replaced by Tung of the Evil Horde and most books were banned for painting a bad light on the Horde, Sera and her school friend Bryan, who both loved to read, were quite dismayed. Serena offered to keep reading books with them at her house, even if it was not allowed by the Horde.
The Evil Horde's next move was round up all the children and take them to the Fright Zone for history lessons. When Bryan and Sera found out, they hurried to Whispering Woods to tell Adora, who thought the children were very brave for doing so.
After She-Ra and the other rebels stopped North Land from burning down and saved the children from being taken to the Fright Zone, the two children made their piece with their classmante Cory, who had helped the Horde at first, but learned the truth about them and had helped free Adora after she was caught. Bryan and Sera offered to help him with his reading skills and be his friend.
