Okay-okay. I'm sorry Nobel but, man, I got a bit of a bone to pick with the character.
Let me get this straight...he's a man that is tall, INCREDIBLY strong-don't deny it, able to wear basically tank armor without reactive technology (Even some jousting armor-armor that is smaller than Lion's-required the wearer to be, not only on the horse, but on a
draft horse to move, since the user could not walk in it) and is harder than steel.
On top of this, he has heightened senses and is educated. He has overwhelming combat capability (I assume you mean with his armor on) and can SENSE DANGER (again, I assume) more accurately than the natural instinct most possess a little of. He also knows a lot of various little bits of trivia about random topics.
Now for his disadvantages:
Is a lone wolf and is too big to hide.
If that isn't over-powered, I don't know what is.
Now...I wouldn't throw this character away-despite what some guys out there believe with WAY over-powered characters, you can tone them down to be reasonable characters without trashing their general idea, so I ain't going to be that asshole that demands it be taken down. :P
Here's what I recommend:
-The guy, at 8'7, is huge. Like, 'HOLY F**KING S**T!!'-huge. We don't want an invulnerable character, so I'd say put him down to around 6'6-7'2, so he's still unbelievably huge but not two inches shorter than
the tallest man ever in our world, and tone down his armor A BUNCH. Here,
this guy ought to give a good example of how he would look...except much better-looking.
-Give him heavier armor than normal but not too much armor. Think a good set of jousting armor,
like this or
this. What you could do is look for a picture of normal armor that looks like that or a little heavier or you could actually
go for a set of jousting armor and add that 'wow' factor of someone fighting in such notoriously-heavy armor, while sacrificing a larger amount of mobility.
-Unless it is magical or blessed in some way, the 'harder-than-steel' material has no basis behind it. It has to have a downfall, whether it is heavier (dear-god that would be hilarious with Lion's armor XD), or way more expensive than normal due to it being forged with a special material or magic. But, even with this armor, he should still be vulnerable to attacks with blunt weaponry and well-placed piercing attacks from something like a sword or longbow (within 100 yards).
-He likely had to buy his armor, If you want full plate armor of good quality, I'd be sure to provide a reason in the backstory for how he afforded it. This should be easy as long as you discuss the situation of his knight order. Keep in mind, the king made him leader, each of our characters are going to likely know a lot about the order already and it's hard if
we know hardly anything about it.
-You gave him a six-foot long blade. To compensate, I'd be sure to mention that he can't attack as fast as someone with a normal weapon, despite his size. Also, to get rid of further balancing issues, he should perform sluggish enough to be classified as
slow compared to a normal man when using his weapon and wearing his armor.
-Unless it is magic ability, seriously dude, get rid of the supernatural senses of danger. Your guy is human-let me remind you.
-In fact, if he uses a helmet with his armor or the armor goes up behind his head, like the original armor (for some UNGODLY stupid reason) I'd recommend putting down that he has decreased ability to look around.
-His shear size makes him a big target. He is likely to take the brunt of almost every ambush and most enemies of normal fights would choose to overwhelm him with numbers.
-I recommend you add to his advantages 'he is quite possibly the most intimidating person anyone's ever had to fight...like...ever'.
-When you put his weight down, it's probably around ~280 lbs. or something without armor. Around 370 lbs. for while he wears the heavy armor I assume you want. Again, this depends on the amount of armor you want for your character. For reference, think of this: the United States Marine Corps' optimal weight is around 165. After bootcamp, most weigh in at close to 200, if not more. That would be an average-sized guy after immense amount of training. Now add 1 1/2 to 2 feet of height on there.
-You never explained what a 'Human Wight' is. Be sure to explain his race in the profile.
Well, that's my two-..uhh~
ten cents on the matter. I seriously recommend making your character less...God-is the only adjective I can think of that fits. The points I mentioned should get rid of any ridiculousness of the character while still keeping him the most powerful out of any future characters (while still having everything being acceptable, so it
is completely reasonable! :P).
