AVP did say something about the Tulcas Autobot:
It is true that I was becoming frustrated with the seemingly endless requests for naming of very minor participants in the war. You asked very nicely, though, and I am feeling wistful about the end of our time together, so I will endeavor to answer.
The first being you speak of is called Headcannon. Very literal, is it not? He is a mighty warrior, but he is also a fan of the many plays of Crosscut. He often would write his own "botfiction" about the characters and situations Crosscut would explore.
