Admiral Bucock from the free planets alliance is memorable too. He is an experienced military man who has seen many battles. His leadership and his relationship with Yang Wen - li add depth to the story. Also, Oberstein in the galactic empire, with his cold and calculating nature, is a character that leaves a strong impression.
Reinhard von Lohengramm is surely one of the most memorable. His ambition and military acumen are remarkable as he rises through the ranks of the galactic empire. Another is Yang Wen - li from the free planets alliance. He is a brilliant strategist who often has to fight against difficult odds.
Siegfried Kircheis is also very memorable. He is Reinhard's loyal friend and confidant in the galactic empire. His unwavering loyalty and sense of justice, despite the often - corrupt environment of the empire, make him stand out. Then there's Julian Mintz, Yang's protege. He is young and full of potential, and his growth throughout the story is quite engaging.
