First

Hm. Let's see how powerful Shade turns out to be. He's already pretty close to an idealised character. Three beautiful mares as his personal harem, but not like those EvilBad stallion rapists cause he's totally nice and they all just love him like that, bigger in the sack than the big canon characters, one of the few "pure" heroes left, feared by the bad guys, able to teleport...

He may need something to balance that out at some point.

7879716 don't worry, he's no Gary Stu, future chapters will show how much he's lost over the course of the invasion.

I'll be curious! Though, it should be noted that having a "tragic backstory" doesn't really count as a character flaw, for example.

7882709 I won't spoil anything but it's not your cliche "Tragic Backstory" you hear so much about. The only real bad stuff that's happened to him happened during the invasion. I'll flesh it out in the next few chapters.
