BumbleBee is the "little brother" of the heroic Autobot faction, constantly striving to prove himself in the eyes of the taller, stronger robots that he respects - especially his leader, Optimus Prime.  A favorite bright yellow outfit anyone would live. Not to be confused with actual bumblebees, bumblebee from transformers is much tougher.
 
You may assimilate and become bublebee himself, but maybe that is a good thing.
