A few examples that go beyond Anakin:
- Ahsoka Tano and Ezra Bridger were both 14 when their stories began.
- Younglings are aged 4-8; so the ones who go up against Hando and his pirates are probably 7-8 years old. While they struggled, they didn't necessarily struggle more than an adult would have - they were starting characters going up against others.
- Zett Jukassa was 10 when he died. He was that bad-*** padawan killed on the temple bridge in front of Organa during the Jedi Purge. Sure, he died, but he managed more than most of the masters.
