As we know, Hoid will be the protagonist of Mistborn era 4, but he is ridiculously overpowered right know.
List of Hoid's powers:
- lightweaving(old Yolen magic & being bonded to a Cryptic)
- Healing(stormlight, possibly Yolen magic)
- Agelessness(Yolen magic?)
- Lerasium Misborn
- Fortune(more old Yolen magic?)
- Surgebinder(he will probably have sworn at least 4 oaths by era 4)
- Worldhopping(by technology or unknown magic?)
- Extensive knowledge about the basically everything(not really a power but hey, knowledge is power right?)
- Ability to speak multiple languages(unless he wastes his time learning a new language everytime he worldhops to a new planet, he probably have some access to Connection)
- Some form of defence against people in other realms(Kelsier got hurt when he tried to touch him in the Cognitive realm)
- Probably have some form of knowledge on Forgery and probably have a bunch of Breaths and unkeyed metalminds stored away somewhere
Brando Sando(yes that what I call him in every circumstance, regards from r/cremposting) probably needs to do something to Hoid or the rest of the Cosmere to actually provide challenges to Hoid
Possible solution 1: Hoid get a major power downgrade before era 4, possibly by the hands of those 17th Shard people who are trying to find him in SA(forgot which book). Or everyone in the Cosmere gets a major power downgrade(maybe due to something major happening with the Shards?)
Possible solution 2: Either all of the main characters encountered in era 4 will be just as overpowered(fighting against people just as old as Hoid or maybe even a Shard) as Hoid or technology has advanced to the point where it can substitute magic(Fabrials, unkeyed Metalminds, maybe even some Elantrian made stuff)
