Grimlock ♥ Ultra Magnus

It explains a lot: why he wanted to take over Latveria, how he got involved with the magic arts, and a lot of why he acts as he does. 

It is not however a flawless telling of his past: it's a little bloated, and while you don't really need six issues to tell this story, it's also not such a problem that I got bored enough to abandon this.   In fact, most of this is interesting, it's just that certain scenes go on for too long: the explanations about his mother at the beginning are one example I can think of.  

There are also issues that are glossed over.  Doom's insistence that Richards messed around with his data, for example, confused me.   Most of the time Doom is extremely logical, so this jump to a conclusion felt far-fetched and incongruous with how he'd been built up as a character.    If this had been told from multiple points of view, or even third person omniscient, you could get some balanced views on why this happen and explore this incongruity in a way that was satisfactory.  Of course, Doom is going to show some emotion, but this is told from his point of view, and he's deluded himself into thinking he's unemotional. 

Even with these flaws, it's a good read.   Doom is a complex character, and while I'd like to see an origin story that does deal with these complexities head on instead of glossing over them, this is what I had to read.
