Riku was born on June 25th, 1995 and is currently 16 years old. When he discovered that he had supernatural powers at the age of 7, he immediately started testing them on others. His father, disgusted, dropped him off at Xavier Institute at the age of 8. Once there, he immediately felt at home and no longer felt lonely. He is currently there and he is still learning to harness complete control over his powers.
He has the power of power augmentation, meaning he can enhance or weaken the powers of others. He can also copy or absorb others' powers to a certain degree, which is not saying very much. He also has super human speed, making him a fast and worthy opponent. However, if he uses his powers too long, He will drain himself of energy and will collapse from exhaustion.
