It was a glorious moment, full of enthusiasm that all the children screamed for, when the boy (Kantaro) raised his necklace to the sky to summon the magnificent JUNGAR!, and flew to enter his chest where he and Jungar would form a superpower to confront the evil aliens.
The Arabic dubbing is good; very expressive and in-sync, but that's the case of most Arabic dubbed cartoons of that time. However, I believe that the episodes did not rely on accurate translation from the original show; but rather it relied on guesses to fill the parts.
Apart from that, Invaders from Space aka Jungar is definitely one of the greatest children's series you can watch in your life.
