A Main Character

Zack Underwood is the main Protagonist of World of Light with shows Hut likes.

He is very kind and willing to help others, even if he’s afraid of a lot.

Zack is also very loyal to his friends, including Phineas Flynn, Ferb Fletcher, Cat Noir (Adrien Agreste) and his girlfriend Melissa Chase.

He was the only fighter able to avoid getting captured by Galeem (although it was later revealed that Melissa, Phineas and Ferb managed to escape mind control).

Powers.
When he’s in his regular form, Zack has a Murphy’s Law Blaster, which allows him to shoot Murphy’s Law anywhere.

He can change into his LumberZack form, gaining an axe and allowing him to deal damage to enemies simply by singing his bands hit song “Chop Away At My Heart”.

As of chapter 6, also known as “Going Separately”, he uses Jedi Phineas’s magic Stormtrooper blaster to transform into Stormtrooper Zack, giving him the armor and the blaster, which was used to free Big Nate Wright from Galeem’s control.

Relationships.
Melissa Chase: Due to previously knowing her before Galeem’s attack, they are very close. They are a couple, which caused Zack to be concerned when she was vaporized by Galeem’s beams in the first chapter.

Cat Noir (Adrien Agreste): He and Cat Noir have become good friends after Zack managed to convince him to fight back against Galeem’s control, and they became better friends after Zack gave Adrien’s Kwami Plagg some Camembert cheese.

Charizard: Zack and Charizard did not get off on the right foot due to Charizard using his fire attacks on him a lot while Cat Noir and Melissa were off fighting. They became decent friends after Charizard was freed from Galeem’s control.

Skidmark: Zack and Skidmark haven’t interacted much.

Phineas and Ferb: Due to knowing the duo before Galeem’s attack, they were already good friends. Their friendship grew when Phineas and Ferb saved the group from Pistachion Power Man in their giant robot.

Bridgette: Zack has not interacted with her whatsoever.

Nate: Even if having just met, Zack was impressed by Nate’s toughness after he took a blast from Stormtrooper Zack’s blaster.
