Aldrin Pesky is Maggie's older 16-year-old brother of Disney's The Buzz On Maggie. It appears that he is well-liked at school and is possibly dating Dawn Swatworthy, one of Maggie's enemies.
As the star jock in many sports, but mostly in football, he sometimes becomes vain and selfish. But as he points out to Maggie, he has practiced long and hard to earn this fame, while she is always cutting corners on the road to success. Of his siblings he seems to tolerate Bella the most and was visibly upset when she went missing. Like Maggie, Aldrin is selfish and only thinks about himself and what he wants but not like her, he cares about his family and friends.
- His name is a reference to Buzz Aldrin, an astronaut.
