I've drawn Talos a couple times already, and he's actually one of my tops in favorite OC characters of mine. His personality is just so fun!!
He's a big strong guy, pretty darned tall, and he's a warrior. Also, a very formidable fighter who refuses to back down.
But despite that, he's also got a huge soft spot and shows immense kindness to those he's on friendly terms with. Especially children, who all love him and look up to him. He absolutely loves children (in a parental sense darn it!) and becomes a gentle, fun, and wise soul around them.

When he fights, he tends to keep a calm, witty and arrogant air to himself, unless it becomes a really intense fight. At that point, he'll stoop down to taunting and laughing, since he loves the adrenaline rush.


Expressions in order from left to right:
Concern, Kindness, Intense fight, flirtatious (doesn't happen often), amnesia (yes he gets this at some point) and a new personality he develops later while he has amnesia.
Hard to explain that last bit, but basically in the Searing comic I made a long time ago, Talos was killed by a spear to the neck. I decided this didn't actually kill him, but put him in a temporary coma and caused some minor paralysis. When he woke up he couldn't remember anything, and wound up traveling with an old charr warrior who happened upon his nearly dead body after the searing began.
