Krüger Helga competes for Germany's junior boxing team in the World Jr. Boxing Tournament, fighting alongside Führer Skorpion. She acts as Skorpion's assistant during matches, employing specialized techniques designed to reflect opponents' attacks back at them. This combined fighting style establishes them as formidable adversaries against Team Japan. Following the tournament arc, Helga shifts allegiance, joining the World Jr. Union. This coalition, which includes former rivals like Napoleon Baroa, Führer Skorpion, and Shadow Jun, forms to challenge the Twelve Gods of Greece, a group of Greek junior boxers surpassing the strength of the official Team Greece. Her participation in this alliance marks narrative progression beyond her initial antagonist role. Helga incorporates a national stereotype reflecting her German origin. Her primary narrative function remains tied to the international boxing tournament setting and the subsequent team-based confrontations.
