Lee Shenlon is a 12 year old student at the Singapore Institute of Technology alongside his friends Christopher Lo and Ali Pajeel. He is also a member of Team S.I.T. Genius with Chris and Ali. He somewhat resents Chris as his rival and strives to become better than him, because he does not want to live in Chris' shadow. He is the heir to the Lee family, and as such feels he must be perfect in all aspects of his life, including Vanguard. He sees his teammates as enemies rather than comrades, and thus, feels he must be better than them. In episode 100, he admits that even though his teammates are his rivals, he still respects them and even admits to them being his friends.
