Spencer Voorheis

Spencer Voorheis, better known as Dad Voorheis or just Dad, is one of the main protagonists of Boastgusters. He is the adopted father of Kye and main character of Part 1. A famous inventor and martial artist, he gave up on his quest to be the strongest to raise his new son.

Personality
Dad is very intelligent but also very full of himself. He tends to overestimate his abilities and run his mouth. Over time, however, he has softened this trait significantly, and he is greatly filled with remorse for how people such as Bradled Lor Starcutter have suffered because of his actions. Once he adopts Kye, he also takes the role of a supportive father figure, who often restricts Kye from doing things such as creating life.

Part 1
Part 1 opens on Dad when he is a young child. He was taken care of by his parents for a bit, and even watched some TV, like Chronicle of the Mufutt Conflict. At some point he is cast out into the streets, where he lives a lonely life. One day, after petting an emaciated cat, he goes to purchase a comic book. This comic book is an issue of Faraday Cage, and shortly thereafter, the character of Faraday Cage appears in real life to Dad and teaches him how to use Chromosomes.

Over the course of his aging from child to adult, he would continue to master Chromosomes and eventually be hired at Nile.net. On his first day of work, and after a stressful presentation with Shelly Nardompson, it turns out that a tournament is being held. Wanting to prove that he is the strongest, he decides to fight in it. One of his coworkers, a Tanuki named Pocky, forms a small rivalry with him.

The next day, he attends the tournament and meets Bradled, a prominent member of the Assassin's Guild, who he partners up with because the tournament is duos. He watches the fight where Pointy Demonboy and Band-aids the Coffer face off against Chadley, who Dad is jealous of because he doesn't need a partner. After this he and Bradled take on Hurt and Kleiner, and though it looks like they're going to lose, they end up achieving victory due to the latter team's romantic complications. Then the two watch the fight between Pocky and his Chromosome Golem Rocky, and the jesters Jotele and Ligle. After Ligle murders Pocky, Dad flies into a rage and jumps into the tournament, but Bradled quickly takes him aside and tells him part of his backstory. Ligle escapes without a trace.

They then watch Alfon and Eduardo's fight with Gon and Kon, and after the former blows the latter out, they watch Jotele go up against Chadley. Then, they fight Eduardo and Alfon, and Alfon is revealed to be a Chromosome Golem like Rocky was, and not actually Eduardo's brother. This emotional revelation allows Dad and Bradled to win this fight. The two of them then go up against Chadley, and after Chadley kills Bradled, Dad unlocks Weeaboo Rage Mode and accidentally kills Chadley, albeit inadvertently.

At work the next day, Dad meets with his boss, Jiffy Bizus, who congratulates him on his tournament win and promotes him. Dad takes umbridge with the fact that Bizus doesn't care about Pocky dying in the fight. When he goes to his computer, he receives an email from Eduardo and Alfon about their place of work, the military facility Lone Star Base.

One lonely night, Dad finds a basket on his doorstep containing an infant Kye and a note from the mysterious B.O.I.S. Having always wanted to be a father, he takes the baby in and starts to raise him as his own.

Between Part 1 and Part 2
At some point, Dad teaches Kye something about Chromosomes, and learns the Uber Summoning Technique. He also meets Joey and learns that his family was killed by Yahtzee.

Part 2
Dad is drafted into the Second Vietnam War in a three-man cell with Frederick Von Freek and Cynthia Horowitz.

When the three of them raid the capitol of Vietnam, they encounter the leader of the Vietnamese war effort: Hanz the Salamander. In a brutal battle, Frederick Von Freek kills Hanz using the same technique (the Ray of Shame) that killed Pocky. Dad recognizes this, and Frederick removes his face to reveal that he was actually Ligle. But then, Ligle takes his face off and reveals that he was Freddie Freaker, God of Destruction, the entire time. After a foreboding message about what he's going to do to Joey, he disappears through the floor and leaves just Dad and Cynthia alone.

After the war, Dad and Kye train in their backyard. Though he wastes some time with the kitties in the brush, he eventually comes out because Chadley returns due to some contrived, unstated reason, and Dad punches him into the sun. Dad then goes inside and greets Celes Voorheis, his biological daughter.

Part 3
Dad arrives briefly at Judkins Middle School to give the Fellas a warning about how Kye can get when he is angry, and also give him his lunchbag which has an excruciatingly detailed drawing of a plague doctor on it.

Part 4
Kye and Dad train together in their backyard, before Dad teaches Kye how to use both the Uber Summoning Technique and Weeaboo Rage Mode, though the latter takes the majority of the day for Kye to master.

Part 5
Dad teaches a curious Kye how to create life using Chromosomes, and gets mad when he creates Archagent Everlasting and Super Stoog. He resolves to make Kye take care of Archagent, but since Super Stoog can't even move, he doesn't worry too much about him.

When Kye returns from Costa Rica, Dad chastises him for being sad over Archagent's "death" over lunch.
