Tontruk held the distinction of being an Esoomian shockboxer. In a period spanning from 3 ABY to 6 ABY, the Calian shockboxer Lobar Aybock achieved victory over Tontruk. This defeat occurred in the second stage of a match that took place on the planet Vycinyth. The circumstances of Tontruk's loss involved his armor becoming ionized due to the shield failing at the armor's central point. Subsequently, Aybock delivered a blow using an ion-charged shockmitt, leading to an ion-out (IO).
