There is literally no way he's weak

There could be

When was he stated to be as strong as nika

That panel doesn’t really show anything…

Ryuma wasn’t in kaido’s time

Ryuma power is unkown he could be weaker or stronger

Zoro will be above Mihawk

Zoro > Ryuma and Zoro over > Mihawk > Shanks

Or Ryuma > Zoro > Mihawk > Shanks

If Shanks with 2 arms was that strong why wasn't he the strongest swordsman? Did he fight with his hands or something

Reyuma has the power of joy boy. He the strongest sword man. PRIME mihawk? He in his prime bro.

Yea Primes in OP can be like 20 years long
