Moon Ho-joon is a South Korean professional Crazyracing Kartrider player and video game streamer.

Moon announced his retirement from individual competitions after winning the 2020 SKT JUMP Kartrider League season 1.

[3] In 2015, he collaborated with Jeon Dae-Woong, Kang Seok-in, and Jang Jin-Hyung to return to the KartRider League.

[citation needed] In 2020, he teamed with Park Do-Hyun, Choi Young-hoon, Bae Sung-bin, and Lee Eun-taek in the first season of the SKT JUMP KartRider League.

[citation needed] In the 4th Kart League, he had advanced to the 1st round final, then collapsed in the 2nd half of the game.

However, he succeeded in winning the third round and was considered a big three with Yoo Im-duk and Cho Hyun-joon, but came in third due to Kang Jin-woo's performance.

[7] The 8th league went straight to the finals, winning the first-round title over Kang Jin-woo and Kim Jun.

He swept the top spots in the long-awaited final, widening the gap with runner-up Jang Jin-hyeong to win an overwhelming victory.

Since then, Moon Ho-jun has shown his best skills during the round, but he has escaped from being unable to win and began sweeping the championship title.

In the final, people expected Jeon Dae-Woong to win the championship, which defeated Moon for three consecutive games, and Moon did not seem to be able to perform his old skills with a poor reputation, overturning all expectations and beating Jeon Dae-Woong and Yoo Young-hyuk after the middle of the final to compete against Park in the run-up to the championship.

[13][14] In the 12th league, despite being in the same group as Yoo Young-hyuk in the preliminaries, he recorded perfect again after a long time and won the winner's game, and was given a yellow rider.

In the final round,[17] the big three were in a close race with Yoo Young-hyuk and Jeon Dae-Woong due to the war.

Since then, both Yoo Young-hyuk and Moon Ho-jun have struggled and can't eat a few points, and have won seven times by finishing first in the last reverse lobby.

[26][27] It changed from the 16th league to a two-man game, and came up with a drastic rule revision, which calls for the use of reinforced parts (instead, the use of a carnation body with a set tuning condition) and the abolition of the hot rider.

At the beginning of the final, Moon Ho-joon and Shin Ha-neul were both sluggish, failing to stop Yoo Young-hyuk and Park Hyun-ho from playing, and Moon Ho-joon revived in the second half and tried to take care of the team by winning five consecutive first place, but Shin lost the title after suffering a serious slump of only 34 points out of 111 points.

[29] On January 10, 2013, he participated in the 17th KartRider League as a team called Mun Myeong-ju and Sailor Moon.

[36] However, Moon Ho-jun was given a green seed in the best-of-breed league as he advanced to the finals as the third-place finisher in the group, but in the 11th and 15th leagues, he lost in the second round to Jeon Dae-Woong and Yoo Young-hyuk and was expected to show better performance than the preliminary round, but ended up in third place in the final with quite a lot of ups and downs.

[37] In the pre-voting for the individual final of the dual race season 2, he was still considered the top favorite, despite his disappointment in the team match and supported by more than a majority of users.

[38][39] He teamed up with Jeon Dae-Woong, Kang Seok-in, and Choi Young-hoon in the 2018 Dual Race Season 3.

While Park In-soo swept the top spot with an overwhelming appearance in the semi-finals, Moon Ho-joon himself was eliminated from fourth place with his form jagged throughout the game.

[52][53] However, he left Startail in October 2014 and was seen playing KartRiders with Korean players such as Chinese professional gamers and Lee Joong-sun in association with Jeon Dae-Woong on an internet broadcast.
