And then I launched my counterattack 
in order to destroy the human world.
.ثمّ شننتُ هجومي المضاد من أجل تدمير عالم البشر
Dann habe ich einen Gegenangriff gestartet,
um die Welt der Menschen zu zerstören.
Y entonces contraataqué
para destruir el mundo humano.
Y entonces contraataqué
para destruir el mundo humano.

E poi, lanciai un contrattacco
per distruggere il mondo degli umani.
E então lancei meu contra-ataque
para destruir o mundo humano.
А затем я напал в ответ, чтобы
разрушить мир людей.
