>>95530781There was GL in the previous episodes, the same one as in this, it's just the first time he does anything and is voiced.
For example, pic related - it's an episode when Amazo attacks the league, Hal is taken out in a few seconds, others in a bit longer, and Bizarro saves the day.
On the other hand, Aquaman not only didn't appear yet, but wasn't even mentioned. I'm worried.
