Xander

You've almost guessed it! The city in "Screechers Wild" is called Zephyr City (or Zephyr City). It's where the main action of the series takes place, and "Ultra World" is the virtual world from Season 5.

Here's some basic information about the city where it all begins:

Status and Atmosphere: This is a futuristic metropolis and the acknowledged capital of screecher battles. The most prestigious championships are held here, and the winners become true stars.
· Main Arena: The most important competitions take place in the Air Arena, which is arguably the main stage for the racers.
Role in the plot: Brothers Xander and Ringo came to Zepher City to fulfill their dream of becoming racers. In the first seasons, they try to rise to the top while also protecting the city from villains like Dr. Odis and the Dark Alliance.

But the "Ultra World" from Season 5 is something else entirely. It's a virtual space built jointly by humans and Screechers. The brothers enter it through special equipment to investigate mysteries and battle on a whole new level.

Level-headed and calm: Xander acts as a mature strategist, in contrast to his impulsive younger brother Ringo.
· A goal-oriented leader: He is focused on winning and knows how to think through a battle plan down to the last detail.
· Kind and loyal: Despite his seriousness, he remains kind and always supports his brother, despite their differences in character.

Given the frame-up storyline, his resilience and leadership qualities likely showed up even stronger in Season 5: he remained composed to face the accusations and relied on Ringo's loyalty, who alone didn't turn on him. Adult Xander became an even more formidable protector this season.

This episode is called "Fake Xander" (the first episode of Season 5). As soon as the brothers enter the Ultra World and become Ultra Guards, a villain appears who uses a double to discredit his older brother. Everyone around him stops believing Xander, and only Ringo, as you said, stays by his side and tries to restore justice. Unfortunately, the sources I've found don't provide the exact name of the guy who pretended to be Xander in Season 5. All available information about the series mainly covers the first few seasons, and Season 5 only provides general plotlines about the brothers and the races. The storyline involving the setup and the double is not explored.

Where can you try to find the answer:

· Fansites and Wikis: Search for Russian or English-language wikis on Screechers Wild — they might have detailed descriptions of the episodes.
· Watching the episode: The surest way is to rewatch the first episode of Season 5, "Fake Xander." The villain's name should definitely be mentioned in the dialogue or credits.
