Not much is known about Sid, except that he is the longest tenured employee in the Assembly Tower's history and that his hearing is not very good because he works in the noisiest part of the Hero Factory. He has once been interviewed by DJ Mak Megahertz on Hero Factory FM. However, the interview did not go very well due to his hearing impairment.
- It is believed that Sid's last name, "Asimo", is based off the ASIMO - a robot being developed in real life.
