The moment the ring disappeared, his wings appeared, allowing him to stay in the air for a few seconds before he decided to descend. He had observed the Shadow Guards, and even without the system, he knew they were now Mutants. Their aura was several times stronger than the last time he saw them. The current version of them wouldn't need even ten minutes to deal with one of the Overlords.
"Why are you guys bowing down?" Karsha was startled to see the Shadow Guards, even Ayarr, go down on their knees and bow when he descended. He was taken aback by their sudden action. He was from Earth, and practices like bowing down to people were only common in countries ruled by a monarchy; in some cultures, it was regarded as a form of greeting.
When someone bows to you, it symbolizes respect, but in most cases, it implies superiority. Karsha didn't know which applied here, so he was taken aback.
