Clash of Titans.

After receiving orders from their superiors to leave Earth untouched, they entered a rigorous training regimen to enhance their abilities. This decision stemmed from their previous mission's failure, a mission that had involved an assassination attempt on another general. Despite their combined strength, they found themselves unable to defeat the man. Their near-death experience was a stark reminder that Earth's fighters were growing stronger. This revelation prompted the council to halt all hostilities with Earth, ordering a recall of their forces until further notice.

However, this decision weighed heavily on Slasher's heart, igniting an unwavering determination within him. His two siblings shared this resolve, and together, they embarked on a relentless training regimen.
