Ragnir.
Ragnir is at the same time one the most powerful weapons out there and the cutest one and its literally since he is one of the few living weapons sentient through Zoan animation. If not for Shamrock Cerberus and possibly Shanks'es Gryphon I would say He Is The Strongest weapon at least on its own since there wasn't a Giant strong enough to defeat Him for centuries and even Loki had some trouble ultimately hitting Ragnir with all he got conq.infusion including to the point his old hammer broke into pieces. Only then Ragnir decided Loki is strong enough to be worthy of consuming Nidhoog Zoan fruit. Whatever he is the strongest or 2-3 seat at worst, Ragnir is the cutest weapon animated object in verse. That face with that cute little ears in base form, I can't 😍
