I'm not sure that ticks all the boxes in the OP. Reckless attack with GWM and PAM do a lot of damage but that can be done on a vengeance paladin with his vow, and the paladin will have the better armor class to avoid hits instead of resistance, and better saving throws, and a healing pool to replace the hit points / damage reduction, and some applicable spells in the list.
2 feats when 3 ASI's are all that's available also hits ability scores. Were you thinking variant human?
Zealot is a strong choice but "can also use his brain and social skills to overcome problems" seems a bit lacking. At least the paladin also has charisma to for that area. Zealot is more like "can tanks some hits" and cranking that up to 11 then ignoring the other listed qualities other than damage.
Fair enough. I may have concentrated to much on the "Juggernaut" aspect as I found the total list of requirements to be all over the place. I'll try again. Although I will say I'm currently playing a Zealot with 14 Wisdom, Perception, Survival and Insight proficiencies. With no Ranger in the party he is the best at spotting ambushes, tracking, and figuring out who is lying. All of which is using his brain and the last one is useful in social encounters.
Anyway I'll suggest a few more based on the OP:
Thanos: Rune Knight Strong, Tough, Armored and uses magical items to augment his abilities
Kratos: I still think we are talking about a Zealot here
Arthas (Warcraft): Oathbreaker Paladin. Conquest Paladin or Hexblade could also work
Hulk: Bear Totem Warrior or Berserker
Geralt (The Witcher): Monster Hunter or Eldritch Knight
Kenpachi Zaraki (Bleach): A guy also not known for his brains or social skills btw: Zealot or Conquest Paladin (for the Fear Aura)
Thor (Marvel): Eldritch Knight using Lightning Spells, Tempest Cleric, Storm Herald
Reinhardt (Overwatch): This is an interesting one. I'd go Cavalier.
Venom: Warlock fits the fluff, and Hexblades are Tough Warlocks.
Shao Kahn (Mortal Kombat): Strong Tough and uses magic, another EK here?
Achilles: Spear and shield, blessed by the gods. Oath of Heroism maybe, possibly also a Zealot?
Hercules: Known for huge feats of strength Bear Totem warrior might fit here or could just be a race with powerful build.
