Samantha "Sam" Lasair
Age: 19
Occupation: Student
Height: 6'0"
Weight: 180 pounds
Eyes: Blue
Boisterous, headstrong, and extremely impatient, Sam is the Aleks's childhood friend as well as unofficial "leader" of the quartet, primarily by virtue of being the first one to spout an idea and overwhelming enough in personality to push the concept through. Has a great dislike of bullies or people who abuse others, and a quick temper to boot, though this has often caused her friction in general life. Has always loved flashing a toothy smile wherever she goes, which only increased in her Kaiju form with its vastly larger fangs.
In a bit of a rock paper scissors paradigm, her evolved state has incredible strengths as well as weaknesses from crippling overspecialization. Her bodies focus on Energy control makes her a living WMD and artillery piece, with the ability to lay waste to anything she hits, as well as extreme physical power to deny anyone trying to close the distance with her; Unfortunately, as her body grows and specializes in each level, her agility proportionally lowers, making her have difficulty with extremely fast or small targets. In essence, this means that Katt could easily evade and whittle Sam down from mid-distance, Sam could decimate Lyn with her destructive power and shrug off her attempts to overpower her, and Lyn could rushdown and demolish Katt.
