A simple question with a not so simple answer

I had no idea that Transformers were so complicated...
When Doug got this "boo boo" (if you can call three stitches a simple "boo boo") I was told that I had to change his band-aid three times a day.
We only had a few kid band-aids left and I really prefer to not wear band-aids with popular cartoon characters on them so I did not want to run through the skin colored ones.

Hence a trip to the pharmacy section of a store was in order.
First Doug and I had an argument in the car about what type of band-aids he could get. He said he wanted Power Ranger band-aids (which I have a personal bias against all the kicking and hitting so I do not permit Power Rager things) and I was suggesting Transformer band-aids.
Well, wouldn't you know that they do not make Power Ranger band-aids and my boy who often "over-labels" or "over-extends" REALLY meant that he wanted Transformer band-aids.

He likes to choose which band-aid he gets and at least there are a bunch of different patterns in the pack. He has actually learned how to open the outer white wrapper on the band-aid.

However, of the Transformers pictured on the band-aids I only know two of them. There is a third one (I'm assuming it is an Autobot since the other two pictured are Optimus Prime and Bumblebee and I KNOW that they are Autobots) that is sort of grey/brown and apparently turns in to a motorcycle.

This lead to the simple question"Who is that one mommy?"

The answer...I had to "try" to look it up.
Did you know that there are multiple eras/worlds/interpretations of Transformers?
Did you know that there are sometimes multiple color schemes for even the same Transformer?
Did you know that most people who have sites with information about Transformers will describe the battle function of the Transformer and even the personality but not necessarily give information about the corresponding vehicle that the robot becomes?
Do you know that some really strange stuff comes up when you start trying to Google info about Transformers?

I did not realize that the Decepticons all became military vehicles and the Autobots tend to be civilian vehicles. I did not realize that there are multiple versions of the back story and arrival of the Transformers depending on which comic, TV show, movie, or toy series you are talking about. Who know? I certainly did not know prior to last night.

I really do not want to know how much time I wasted spent Internet surfing trying to find the answer. My best bet is that it "might" be the Autobot named "Groove" but I am not entirely convinced.
Perhaps if I somehow find some "spare" time I can do some more searching.
