The seventeen-year-old future version of Betty as seen in the series finale of Atomic Betty, The Future Is Now!, who will presumably be the "all grown up" Atomic Betty in this series.
Atomic Betty Redux is a recently announced series currently in production. Atomic Cartoons made the announcement via their updated website in June 2016. The show was expected to come out in 2010, but all references and mentions were removed.
Details are unknown at this time, but it has been revealed that Betty will be "all grown up", which could mean she'll either be a teenager or an adult. She first appeared in the episode The Future Is Now!. It was the last episode before the original series "Atomic Betty" ended on January 29, 2008. [1]
However, all references to this proposed series were removed from Atomic Cartoons' official website, and any news haven't been heard since.
