Tanya Spears' first appearance in Worlds Finest #23 and her first acknowledgment of the Power Girl identity in #26. She is described as one of the "most intelligent 17-year-olds on the planet" by co-creator Paul Levitz.
But in a big splash appearing in today's DC Comics, to announce her joining the Teen Titans in issue 5, she's been de-aged by editor Eddie Berganza to "just 16 years of age".
It may be just a year. But to Tanya that's a whole sixteenth of her life Eddie has just removed. Or seventeenth.
Depending on which state she lives in, that could affect whether she can vote in primary caucuses. or if she has reached the age of consent or not, both very important issues to a teenager. In New York, that's no and yes, respectively, but the Teen Titans do get around..
Someone sort this one out! It's important!
