Max is a young adult with a bushy hair and spiked nose. He is seen wearing a white coat and oval glasses, along with gloves.
Carlos is shown to have great persistence keeping himself awake for thousands of years in order to serve Luna.
Abilities and Skills
- Bodyguard: Before the Petrification, Max was employed as Luna's bodyguard.
- Shooting: Max seems to know how to wield a gun, pointing it at Taiju when he approaches too quickly.
- Handgun: A small handgun, unlike most of the other Americans' larger weapons. It seems to be at least partially concealable but quickly drawable.
After his revival, Max at some point became an employee of Dr. Xeno.
Max and Carlos accompanied Luna and Stanley through the forest. Carlos and Max tried to impress Luna with a display of strength by carrying the supplies, with her shrugging off their advances before Stanley tells her that she has to preserve her strength because she has a role to play. After gathering a good vantage point, he catches a glimpse of the Perseus and remarked that the science leader is nothing to Xeno. Max is nervous when Stanley insists on killing the leader. Moving the questions further, she asks why he needs her and the reason for her clothes, as Max thought it was because of Stanley’s preference. Stanley explains that he will send Luna to spy on the Kingdom of Science to draw out the science user for him to snipe him. Max is scared by Stanley's preparation for a sniper attack.
Max stayed at the vantage point with Stanley and Carlos and was worried about how Luna was going to integrate with the crew of the Perseus. Carlos was notably disturbed by Stanley’s eagerness to assassinate the science user of the Perseus.
Max would be petrified alongside the rest of his comrades as the petrification beam that was launched from America reaches South America.
Three years later, Max's statue is collected by Suika who was revived earlier. She places Max with her other collected allies.
After the revival of everyone else, Senku revives Max, along with Carlos, Chrome, and Kaseki. Max watched as Tsukasa and Hyoga later hunted several animals and used their pelts to make new outfits for everyone. That night, he and Carlos watched Luna attempt to flirt with Senku at the celebration. 
When Xeno is revived, he and Carlos agree that he might betray them but Chrome disagrees with them.
