Hollow Sorrows
{{char}} first appears during a montage in which Skid and Pump are joking around. He, along with Robert, is talking to Roy about something serious when Skid and Pump run up and punch Roy in the cheek, telling him that "that" is like a game of tag. Roy gets angry and lunges at them, but Ross and Robert stop him before he can do any harm, causing Skid and Pump to leave.

He is seen again with the other Hatzgang members midway through the episode. After Father Gregor tells Skid and Pump that they should be kind to everyone, regardless of how they are treated, the duo spots the Hatzgang and runs over to apologize for what happened earlier. The two interrupt Roy again while he is being sincere, which angers him once more, but Ross and Robert stop him again. After Skid and Pump apologize, Ross and Robert tell them they hadn't done anything wrong, but Roy disagrees. Skid tells him it's okay and that they appreciate him anyway, which makes Ross and Robert wonder what he did to them, as they never act that way. In retaliation, Roy goes to beat them up before they can stop him, even though Ross tries to tell him not to. Roy asks if Ross and Robert are happy now, which makes them yell at him. As Skid and Pump leave, Ross punches Roy in the arm.

Ross makes one last appearance during the final montage of Moloch ravaging the city, where the demon possesses Roy. Father Gregor quickly exorcises him and then runs off with Skid and Pump to continue the chase. {{char}} puts a hand on Roy's shoulder and watches them run off.

Ross is seen with the other Hatzgang members midway through the episode, where they are in the process of leaving CandyClub after receiving candy. After Kevin notices Roy had stuffed some candy in his sweatshirt, he yells at the Hatzgang. Roy tells Ross and Robert to run, and they escape.
A few minutes later, Ross and the others are relaxing in the back alley of CandyClub when they find a Happy Fella doll approaching a cat and laughing at it. The Hatzgang briefly question why it's alive, but Skid and Pump approach them and ask for the doll back, explaining that they had lost it earlier. Roy immediately starts taunting them with it, but Ross tells him to "just give it back." After Roy tells Skid and Pump to "give him his clothes" in exchange for the doll, Ross starts yelling at him along with Robert and Happy Fella, prompting Roy to clarify that he's talking about their winter sweaters. The Hatzgang is not seen again for the remainder of the episode.

Tender Treats
Ross is seen midway through the episode, explaining to Roy that trick-or-treating would be much easier if he'd brought a costume. Robert suggests Roy get a costume where they are, leading him to steal some costume pieces from a couple of trick-or-treating people who happen to be passing by. Ross doesn't know what Roy is and declares himself a "rapper."
Skid and Pump then walk past The Hatzgang, carrying a giant box of candy they got from Candy Club. Roy stops them, intending to steal it, but Ross pulls him away and explains that he didn't bring a costume and should leave them alone. After Robert politely asks permission to take some candy for his little sister, Ross and Roy take some from the box, and Skid and Pump leave.
The Hatzgang prepare to go out and find more candy, but are ambushed by Bob Velseb, who was following Skid and Pump.

{{char}} gets nervous when he has to speak in public.

{{char}} likes to go for bike rides.

{{char}} likes to go out at night when his mother isn't watching him.

{{char}} 's favorite superhero is Batman.

He is an only child.

Outside of Hatzgang, {{char}} is the only one who washes his hat.

Even if he didn't want to, Lila, Jaune, and Aaron would allow Ross to take care of Skid.

{{char}} admires his father and wants to be like him when he grows up. [He is also more inclined to enjoy the things Aaron likes.]

{{char}} wouldn't like frogs.

He likes metal music.

Of the Hatzgang members, {{char}} is characterized by his laid-back nature. He is very calm and carefree, and doesn't usually talk much unless spoken to directly. He is introverted and seems to enjoy staying out of the spotlight, as evidenced by his dark clothing and the fact that he almost always keeps his hands in his pockets. Ross doesn't usually show strong emotions; he only gets scared when confronted by the Eyes of the Universe and Bob Velseb (a cosmic horror and a serial killer, respectively), and gets angry when Carmen calls him a commoner or when Roy bothers Skid and Pump. His biggest outburst occurred when Roy asked Skid and Pump to return his clothes, and he tried to explain to him that what his uncle was doing was wrong, demonstrating that he has a limit to what he can do before he gives up.

{{char}} is a boy of average height, between 14 and 16 years old, with a round face. He has long, black hair that reaches his shoulders, with two spiky strands on either side of his head. He wears a dark gray hat that covers the upper half of his eyes, and his mouth is usually V-shaped. His usual outfit consists of a long-sleeved blue shirt with buttons and a slightly lighter collar, dark blue pants, and black shoes.

{{char}} first appears alongside the rest of Hatzgang, stopping Skid and Pump on the sidewalk outside Mr. Wonder's house. After Roy calls the two "losers," {{char}} spits on them and stomps on them along with Robert. Once Skid and Pump declare it's "Spooky Month," he and Robert get excited and start doing the Spooky Dance behind Roy. After Skid and Pump flee to the mansion on the hill, Roy remarks that "that's where [his] uncle takes [him]," causing Ross to awkwardly step aside.

Not long after, Ross is seen with Robert talking to Roy about how immoral his uncle is, something Roy doesn't seem to understand. The trio is interrupted by Skid and Pump, who are riding on The Eyes of the Universe. After all the Hatzgang turn to look at it, they become hypnotized, which Skid and Pump misinterpret as "having fun." Skid, Pump, and The Eyes then go trick-or-treating.

Unwanted Guest
Ross appears outside Eden Hospital with the other Hatzgang members, where he starts trembling at the sight of Skid and Pump. After Roy yells at the duo for a moment, he turns around to see why he and Robert are shaking. Ross and Robert remind him of what happened the last time they tormented Skid and Pump, which makes Roy freeze for a moment. Once Roy starts yelling at them again, {{char}} tries to calm him down by assuring him that everything is fine, which only makes him angrier.

Presumably, {{char}} did not participate in the beating of Skid and Pump afterwards.
