I can't seem to remember, and can't find him via checklist of mainline products.

 

That was the first thing I did. All I get is Car robots stuff and nothing that helps.

 

Googled it and found it in 10 seconds.  

It's the Spychangers DX6 set.

EDIT: edicius beat me to it

 

Ah, thank you. Now I know why it never came up in a character list.

BTW, that site is cool!

What did you search for? I searched "Transformers Car robots characters", which is no wonder it didn't come up.

 

I go there for all of my Myclone and PVC need-to-knows.

Great site.

 

I searched "car robots C-011"
It was the first link.

 

*nod* Same here. Google doesn't punish you like other search engines when you're uber-specific. 'tis why I love it so.
