Sam Peters, Jr.

Hayden Derek Peters is Jo's second-youngest brother in the Fighter series.

Description
''Jo's third youngest brother and the most hot-headed. Despite being just a fifth-grader, Hayden knows how to hold his ground and fight, even if it means sacrificing everything.''

Physical Appearance
Hayden is the sole Peters' kid to inherit both his uncle's black, inky hair and hazel eyes. He also has pale skin and often wears shorts, a blue hooded sweatshirt, and worn-down high tops.

Personality
Hayden is described by Jo as hot-headed and impulsive when it comes to fighting, but this later shows to be helpful when it protects him, Luke, and Alex from getting crushed by Nathan. This seems to stem from his protectiveness, as seen when a bully brings up the subject of his late mother and he attacks him.

He is also shown to be angry at the fact that he has Nathan's powers and that he's an orphan, as shown when he runs away into the forest to figure out how to take his uncle down.

Former Powers/Abilities
Light/Dark Elemental Powers: Hayden inherited his uncle's powers (lightning and shadow manipulation) but also has light powers combined with them, making him a fearsome opponent and a powerful elemental. This combined strength also makes him a lesser victim to corrupt, unlike his brother Josh.
 * Shield Generation: is able to generate a shield of light/darkness by pure willpower. The emotion known to trigger this power is still unknown, but it's thought to be protectiveness.
 * Weapon Generation: is able to create weapons by will, such as a dagger, spear, or rod.

Swordsmanship: is shown to be naturally adept at fighting with a sword during the battle against Nathan

Hand-to-Hand Combat: since Hayden is prone to start and end fights, he is increasingly skilled with street fighting tactics along with defensive and offensive fighting tricks

Current Powers
Ghost Powers: as a spirit, Hayden harbors common ghost powers.
 * Intangibility: Sam cannot be touched and is able to phase through walls
 * Levitation: Sam is able to float above the ground as a ghost
 * Invisibility: Sam can become invisible to the human eye if he wills to
