Liam himself
Liam is a close friend of Rolf Maxwell and Fiona Flagstaff who is treated as a outcast from his school mainly due to him be "considered weird looking and acting" due to him having Asperger's Syndrome but he's liked and accepted by the DinoSquad after they learned the errors of trying to shun him as well, Liam is really intelligent and can recall facts with extreme ease. Liam was also entered into the DinoSquad team as he keeps the team's secret of turning into dinosaurs, as well thanks to his expert knowledge on insects especially bees he can help the team identify and defeat mutated bug based dinosaurs. Liam is also pretty special being the only current (as of 2021) animated character with Asperger's Syndrome.
