I've been playing Skyrim again recently and now I thought about the KND in the Elder Scrolls series (mostly Skyrim cause that's the only game I played in the series, lol).
A few KND characters if they were in Skyrim (that I can think the best builds for them):
Chad (Numbuh 274): Nord, basic warrior build. The most basic build he can ever have, sword and shield, heavy armor, with a little bit of healing magic. His Battle Cry ability makes enemies flee for about 30 seconds, would probably use that to heal up and regain some stamina while they flee. That's all I got for him basically.
Rachel (Numbuh 362): Khajiit, stealth build. She used to be a spy for the KND so it wouldn't be surprising if she did a stealth build (also she would carry some invisibility potions just in case), she's skilled in lockpicking just to unlock a door, deactivate a trap, or unlock a chest/safe to get the adults' plans. She would use her own claws or bow and arrows if she's in a fight, yeah I think she ended up getting some lessons in two-handed when she became supreme leader because her sign weapon looks like a two-handed weapon. She wears light armor for more efficient sneaking, makes less noise.
Lenny (Numbuh 0.4): Redguard, unarmed build. I think it's obvious what build he would do, brawler's gauntlets are basically boxing gloves, but since the brawler's gauntlets don't do anything other than give you extra unarmed damaged I decided he would also do some shock magic, also invest in some healing and alteration magic just in case. Lenny wears heavy armor since he can take more hits while he punches. Adrenaline Rush (the Redguard's ability) would help with stamina regeneration if he's in a tough situation where he needs it badly.
David (Numbuh 0.2): High Elf (aka Altmer), battlemage build. You might as well have a mage in a KND sector. He would help his teammates by healing them and conjure an atronach for help in battles. Would carry a staff just in case, his weapon of choice would be a Bound Battleaxe (there are no spears in Skyrim, sorry). His Highborn ability allows him to regenerate his Magicka if he doesn't have any magicka potions and uses it as an emergency magicka regen. He has a Amulet of Akatosh for magicka regeneration if he already used his ability and only has a few or no magicka potions. David can enchant armor, weapons, and jewelry for his teammates or other operatives. Heavy or light armor, it really depends.
Bruce (Numbuh 0.1): Orc, dual wielding build. No nunchucks in Skyrim unfortunately, so I have to give him war axes as substitute. He has light armor so he can move faster and take advantage of of the Wind Walker perk (50% stamina regeneration in all light armor). His Beserker Rage ability allows him to take half the damage and deal double the damage if he's facing a really strong enemy or multiple enemies. Is skilled at smithing, will make and improve weapons and armor if asked, he often works with Alessandra if he wants to smith or improve something.
Alessandra (Numbuh 0.3): Orc, two-handed warrior build. Her weapon of choice is always the great sword, she is skilled in the blade. Her armor of choice is heavy armor so she can take more hits while she swings her great sword. Like Bruce, her Berserker Rage ability is useful in battles against strong or multiple enemies. She's skilled at smithing like Bruce, they work together to make good armors and weapons for other KND Operatives.
Constance (Numbuh 0.5): Argonian, assassin build. A silent but deadly operative, they won't notice she's there until it's too late. Skilled at archery, daggers, alchemy, and stealth (basically anything that assassins knows). Makes strong poisons, paralyzing, and invisibility potions, can make some magicka, stamina, and health potions for her teammates. Knows every poison, paralyzing and invisibility ingredient in the assassins' alchemy book. She's not great dealing with frost due to frost being an Argonian's weakness but give her frost resistance and she'll be okay, even giving her frost resistance potions or the ingredients for frost resistance would be enough. Since she has water breathing, she can go underwater for long periods of time to hide or retrieve something. She would use her Histskin ability as an emergency health regeneration if necessary. She wears light armor since it's recommended for a build like this.
The KND in the Elder Scrolls universe would be wild.
I based Lenny's build on my current build which is the same as I described here except for the fact my build includes my character being a werewolf. Would Lenny be a werewolf if he were in Skyrim? Maybe, it depends.
That's all I got to say here (possibly for now). Y'all probably didn't know what I was saying here, maybe ya do but I don't know if there's KND fans who know or at least played the Elder Scrolls series or just Skyrim like me.
