Isaac and Ischke Waalenberg

Isaak and and Ischke Waalenberg are the youngest heirs of the Waalenberg family. They are Sonneknige. Like Gunther.

In Black Order, they followed Gray and his team, they were called by their grandfather to eliminate the team.

They were on the eye sight of the Sigma Force team.

They were genetically spliced with hyena DNA. Their grandfather was interested in eugenics and had tested so many changes for embry os. He had produced a pair, them, that was considered perfect. He had added DNA from hyenas, an act compared to cross-poollination. This explained the ability to communicate with hyenas. This ability was used to kindap Marcia Fairfield while maintaining the cover of a lion attack. In addition, while Gray made an attempt to escape, he had kicked her down into the wils while a eugenics-grown-hyena, grown to 5 times a nomral size, was able to stop on command and gleefully listen to Ischke, behaviour Gray compared to how a dog reacted to a human.
