Four

The CJV languages require a counter or classifier for 'person'. That is, 'four champions' must be expressed as 'four-person champions'.

Mongolian has no such requirement. However, the number дөрөв döröv 'four' must add an -н -n to link to the following word.

The Vietnamese adds a dynamic aspect to the title, capturing the upset at the emergence of a fourth name from the Goblet of Fire.

Champion

Champion is translated with different nuances at each translation.

The Chinese-language translations emphasise the notion of the four as 'fighters' or 'warriors'.
The Vietnamese and Mongolian literally interpret champion as meaning 'winner' or 'titleholder'.
The Japanese interprets the word 'champion' as meaning that the athletes represent their schools.
