Swain as the main character of Overlord is the first thing I think of.
My favourite anime is a hard one. Log Horizon, Serial Experiments Lain, and Nausicaa of the Valley of the Wind all rank very high for me so I will do those.
Log Horizon: Galio as Naostugu. He has the friendly big bulky tank demeanor down just right. Alternatively Viktor as Shiroe.
Serial Experiments Lain. Obvious choice here would be Annie as Lain for a couple different reasons. Young, Bears, not quiet like she seems.
Nausicaa is a hard one. Taliyah? That sounds about right. Similar attitudes and I think Taliyah would love to fly.
Of course I have to fit Taric into something. I am tempted to say he could fulfill Raki from Claymore. They both look beyond their expectations to see beauty within and protect that beauty even at the cost of their lives. Otherwise I would go with Yoshimura from Tokyo Ghoul. Though they have very different pasts and goals their mannerisms are quite similar. Yoshimura even looks quite similar to how I would imagine an older Taric.
