Serra was born as Karnage and Helias newborn daughter, raised in an army group where she was taught guns and weaponry. Everything changed when Karnage turned into a big scum, then turning from his own army for power from Nexus making him strong he destroyed the entire army base. Serra seeing this was not expecting or hoping this would happen. To make a long story short, she have spent her life as a shy, normal dino, she didn't really have any goals or strength, just support from others, including Kore her friend like sister. As time grew more and more, she began to grow more and more stronger, training testing her limits, gaining new power beyond that. Everything she did just to lead to this moment where she had so much confidence that she became the most strongest (and overpowered) being in the world. That and plus starting a new life, being with a new bf, and starting a new family which one day she would influence everyone to stay strong, being more stronger and more better with no regrets.
