Alex Peters

Alexander "Alex" Gabriel Peters is Jo's adoptive second-oldest brother in the Fighter series.

Description
T''he middle child of the Peters' kids and Jo's second youngest brother. Despite being quiet most of the time, he will fight and stand up for himself and his family in dangerous situations. ''

Physical Appearance
Alex is a young, 11-year-old boy with blond hair, grey eyes, and fair skin. He wears T-shirts with graphic designs, athletic shorts, and sneakers most of the time.

He is not physically seen in Our Time to Shine, but he is implied to have grown into a 20-year-old man who is trying to work up the courage to ask his girlfriend to marry him.

Personality
Alex is used to being overlooked as the middle kid, which is probably why he's quiet so much. He doesn't really play a major role until the sequel, where we see much more of his protective side towards Luke, as well as his bravery, where he yelled at the ghost to get away from his brother before unwittingly attacking him.

Powers/Abilities
Ferrokinesis: has the ability to move metal with his mind. Like Jo, this power is purely linked to his emotions, which corresponds to his intelligent and creative personality.

Hand-to-Hand Combat: more of a free-style fighter, but still adept due to living on the streets.

Above-Average Intellect: as mentioned in the first book, Alex is much smarter than most kids his age, being able to due high school math and chemistry already.

Jo
While their relationship is not explored much until the sequel, it is abundantly clear that Jo and Alex share a close bond, as when he couldn't remember his last name, Jo let him have hers, showing her empathy for orphans and letting the boy into her family.

However, in Breaking Chains To Form Bonds, Jo has an outburst where she declares that Alex "isn't [her] brother, anyways", causing Alex to break down emotionally. This heavily hints that Alex isn't really her brother by blood, but rather her adoptive younger brother.

Luke
Alex has a older brother-younger brother relationship with Luke, as seen in the first book where Alex shields him with his own body to protect him from falling debris. In the sequel, Luke runs to him after Sam had died for comfort, and later Alex protects his little brother from being harmed further by the black ghost (later revealed to be Jacob).
