What should my skills/special/build etc. be for a PURE MELEE/UNARMED charector? please help me and i will apperciate any help gladly

I went with 9 Strength and 1 Luck for a no-crit build with Heavy Handed.

Amazing perks for any melee build include:

Super Slam
Piercing Strike
Toughness
Action Boy (The Mauler attack with Oh, Baby is a guaranteed knockdown from Super Slam, so more AP is godly)
Stonewall (gives you the DT boost as long as your melee/unarmed weapon is equipped)
Slayer

Stealth is an excellent compliment to close quarters fighting however it isn't a requirement, I recently hit level 30 with a melee/unarmed character and specifically stayed away from stealth. There are some greak perks out there, Super Slam is perhaps a little overpowered (especially with the mauler special VATS strike, yowzah) and Piercing Strike and Purifier are both excellent. Unstoppable Force is good, I'll admit it didn't come up as often as I thought it would but it was still useful. I never got knocked down often but if you have the free slot I'd still recommend Stonewall

Slayer is fun but by then I could already take on just about anything with little risk so it didn't have as much impact as I expected.

The only time my melee character has been knocked down was when I used Euclid's C-Finder while standing too close to the explosion. I took Stonewall purely for the extra 6 DT.

In my opinion stealth + melee is not fun at all. Also, I put my character with 1 per, 9 str, 9 end, and 6 agility. I got ED-E so perception was practically useless because of his perk plus he's basically a flying pack mule. You'll be making so much money selling all the guns, ammo, etc. you'll be able to buy the str, end, agility, and sub-dermal armor pretty early and still have some money left over. As for perks choose all the ones above and both ranks of toughness. This way even when your completely naked you'll have like 10 dt. For skill points put 5 into melee and unarmed each level and the rest into whatever you feel like at the time. This is what I've been doing and I have to say it is extremely fun, especially after you get the ballistic fist and Veronica with a Pushy, perfect combo.

S 7 (whatever you are planning add an extra point to compensate for Rad Child critical/deadly rad poisoning)
P 5
E 5
C 1
I 7
A 5 (melee doesn't need to use VATS as much, esp once you get Super Slam you can knock everybody down without touching VATS)
L 10 (nearly every hit will already be critical; no need for Finesse perk; no need for implant or Intense training)

Implants
STR +1
END +1 (neutral cost; END implant does not use up implant slot because it adds one more slot)
INT +1
AGI +1 (qualify for Silent Running)
PER +1 (qualify for Better Criticals)
Sub-Dermal Armor (+4 DT)

Perk Suggestions
Whiskey Rose (Cass companion perk, provides +2 STR and +4 DT to +6 DT by constantly drinking whiskey; if you take this perk maybe you can put one or two SPECIAL points less into STR)
Super Slam (requires Melee 45; allows you to wipe out large groups of enemies without breaking a sweat)
Rad Child (requires Survival 70; allows you to regen +6HP/sec to +8HP/sec if you stay at critical or deadly rad poisoning, 60-80 times more effective than Monocyte Breeder Implant)
Comprehension (permanent +20 science and permanent +16 each other skill if you find all the skill books; each magazine provides temporary +20 points)
Toughness x 2 ranks (+6 DT)
Stonewall (+5 DT vs. melee, also makes you immune to knockdowns)
Jury Rigger (requires 90 repair, makes repairing armor and super sledge much cheaper)
Piercing Strike(requires Unarmed 70; negates 15 DT on opponents)
Purifier (+50% damage with melee & unarmed vs super mutants, deathclaws, nightstalkers, ghouls)
Silent Running (requires Sneak 60, Agi 6)
Unstoppable Force (requires Melee 90; melee damage breaks through enemy blocks)
Khan Trick (free perk, requires passing Great Khan dialogue check)
Legion Assault (free perk, requires dialogue check with Lucius, 50 unarmed)
Ranger Takedown (free perk, requires dialogue check with Ranger Andy)
Scribe Counter (free perk, requires giving Veronica formalwear)
Meat of Champions (free perk, requires cannibalism and special quest)

Perks to Avoid
Intense Training
Educated (only 15 perks in the game, don't use one up to get a few extra skill points because you can use magazines for +20 points any time you need to reach 100 or pass a high dialogue check)
Here and Now
Monocyte Breeder Implant (useless)

Recommended weapons
Machete, Lead Pipe, Tire Iron (early game)
Rebar Club or Super Sledge (later game)

Aid
If you constantly drink whiskey, eat bighorner or bramin steaks and/or ant nectar, you can stack several STR bonus points (allowing you to keep your effective STR around 10, even with rad poisoning penalty) and the whiskey will give you +4 DT to +6DT if you have Whiskey Rose perk.

Tagged Skills
Melee (try to get to 45 quickly so you can get Super Slam)
Unarmed or Sneaking
Lockpick (never go above 64 lockpick because there are 4 Tumblers Today that will bring you to 80 and then you can use skill magazine for any Very Hard locks, same goes for Science and make sure to max out Speech (after finding all 4 Lying Congressional Style books) at 30-35 points below the toughest speech check you want to pass because you can use Naughty Nightwear + Party Mentats + Meeting People magazine to pass)

Yeah, unless your inside a building, stealth with a melee/unarmed build is a little difficult. You can usually sneak up on one enemy outside before the others turn and see you. Which means you maxed sneak just so you could get one free kill. Inside a building though, you can take them out without being noticed. Some enemies with a ten in perception are almost impossible to sneak up on though.

I guess the close combat + stealth combo isn't as devastating in FONV as it is in FO3, and here I thought I was avoiding an over-powered build
