Luka Doncic has described Zion Williamson as "a different beast", the like of which the NBA has never seen before.

Williamson, the first overall pick in the 2019 NBA Draft, had back-to-back 30-point games for the New Orleans Pelicans prior to the All-Star Game in Chicago this weekend.

The teenager has scored at least 20 points in eight of his first 10 NBA appearances - with five-time MVP Michael Jordan the last rookie to achieve such a feat - and is averaging 22.1 points after returning from a knee injury that delayed the start of his much-anticipated debut season.

Doncic will face Williamson in the Rising Stars Challenge on Friday when Team World face Team USA and the Slovenian has been highly impressed by the Pels forward's adaptation to the NBA.

"You can see he's a beast," Doncic told reporters.

"What's he played - 10 games? He's averaging like 25 [points].

"He's a different beast. I don't think we've seen a player like him. He's going to be an amazing player."

Should Williamson continue to put up huge numbers, he could succeed Doncic in winning the Rookie of the Year award.

The Dallas Mavericks star has enjoyed a fine sophomore season too, averaging 28.9 points, 9.5 rebounds and 8.7 assists.

Along with reigning MVP and Greece international Giannis Antetokounmpo and Serbian center Nikola Jokic, Doncic is one of several international players currently starring in the NBA.

"There's a lot of international players that are really good," Doncic added.

"That's what it shows in this All-Star [Weekend] - there's a lot of international players.

"The world can see that we can play basketball too."
