Trivia

• Ulrich is, by far, the most muscular and physically developed member of the group. A few fans have nicknamed him "The King of Spandex".
• Ulrich, like most of the others, uses a skateboard to travel to the Factory.
• Ulrich despises Sissi, or, at least, just doesn't like her, mostly because she is a selfish, spoiled brat and is always chasing him.
• Ulrich's last name (Stern), Odd's last name (Della Robbia), and Jeremie's last name (Belpois) can be heard in Exploration.
• In The Chips Are Down, Ulrich was temporarily banned from the team after Jeremie and the others found out about him activating a time reversion. He was brought back into the group after he confessed that his actions were selfish and disrespectful. There is a dramatic irony in this, as others of Team Lyoko have used the Supercomputer to their advantage.
• Ulrich was on the Kadic soccer team in a few episodes of the first season, most notably Zero Gravity Zone. In the second season, there is no mention of the team or Jim's coaching job, so it's likely that the team was disassembled.
• Ulrich was the only one seen in virtual form in the pilot, Garage Kids
• He is William's rival.
• He took down the Kolossus all on his own.
• In the episode Hard Luck he is seen in green boxers.
• Ulrich is the only one gain a new weapon (his extra katana) in the fourth season; the other members of the group received theirs in the 2nd-3rd seasons (Odd gaining over 10,000 lazer arrows, Yumi gaining an extra fan, and Aelita's energy fields)
• Interestingly, in season one whenever he was devirtualised, he was not shown coming out of the scanners. The only exception to this is in Killer Music.
• He played the keyboard in the Pop Rock Progressives.
• Other than William, Ulrich is the only member of Team Lyoko who has not piloted the Skid.
• He saves Yumi from falling into the Digital Sea multiple times.
