Leo from trainee A said in his vlog uploaded on their youtube account that all Hybe trainees were going to be competing in a showdown. Trainees across all labels (BigHit Music, Pledis, Source Music, and KOZ Entertainment) will have a competition among themselves called Showdown, and it's the 6th Showdown already held. 

In the vlog, Leo said, "What's new for this Showdown is we perform with other labels trainees. That's new because we only did it among trainees in our company but now we have perform and compete with other labels trainees."

So before this competition, the competitions were only held amongst trainees under the same company trainees, but for this Showdown, they're all doing it together.

In these vlogs, both male and female trainees can be seen either waiting in the audience for their turn or up on stage competing with the trainee a members.

The trainees go through multiple rounds of rapping, singing, and dancing during the competition.

If you don't know Leo or Trainee A, then here's a quick rundown. Leo is a member of the a group of trainees under Hybe. They upload videos and vlogs of them practicing and many other things. Their Instagram is followed by many Hybe staff such as Bang PD/ Bang Shi Hyuk, Pdogg, Hissnoise, Slow rabbit, Chorong (sound engineer under Hybe), Lee ByungEun/Bangster (Hybe performance director), Lee Sun Kyoung (Visual Creative Director), Frants (Producer), Yeonhwa (Visual Creative Director), and others.

During a vlog, they discussed why Jihoon, a member of their team, couldn't compete in the competition. It was revealed that Jihoon's rank fell down, and was unable to perform with the other trainees. So it appears that only trainees with higher ranks can compete in this Showdown competition.
