M6 is one of my original transformers. The body/shell he currently has is really his second body. His first body was his original Guardian form (it's a long story) but I haven't done any designs for it yet until now. I'm still working on the design look.

I wanted him to be feral looking, like a predator or monster. His alternate form would be similar to a jet, but with some avian qualities.

The Guardians are original concept created by a friend of mine. We are merging our transformers universes together along with someone else's to make one big epic alternate universe. All of our characters were created in alternate universe settings. My own was mostly based on G1.

Here is a bit of the history, for those who care/are bored enough to continue reading.

A looong ass time ago, the Guardians were created. Their purpose was to be the protectors of all the aspects of Primus. They were near immortal and extremely powerful. M6 was an aggressive Guardian, choosing to act first and destroy threats before they happened. Many races and planets were wiped out by him, but it was all for the greater good of Primus.

There is much more history, but I'd be a sea of text. I'll just say M6 payed for his overconfident and destructive ways. Karma is a bitch.
