Barbie's "family tree" has expanded over the years to include numerous diverse and multicultural friends. Teresa was among these, being depicted as Hispanic, Italian or Latin. She first appeared in 1988 in the "California Dream" line alongside Barbie, Ken, Christie and Midge (who made her comeback in this line). Christie had been Barbie's most featured friend at the time, being featured continuously in the playline since 1968. It wasn't till 2004, when Christie was discontinued after the "Really Rosy" line, that Teresa would become Barbie's most frequent companion after Ken.Since then Barbie and Teresa are still best friends.
Teresa has been seen in various Barbie-related media such as books, magazines, video games and movies such as "Barbie and the Diamond Castle," "Barbie and the Three Musketeers" and "Barbie in A Mermaid Tale", but she made her first appearance in "Barbie of Swan Lake" where she played the Fairy Queen. She currently appears in the web series "Life in the Dreamhouse", where she plays herself.
