Imagine still thinking Venus is Top 5 Swordsmen or that He is Zoro's Main Opponent
I already said before, don't expect too much from Gorosei, They are more like a Talking Weapon of Mass Destruction
But when it comes to Combat Skills, Weaker SHs can handle them
I mentioned before that Imu might probably be Defeated by Usopp
And Five Elders by Non-Monster Four SHs (Franky, Robin, Brook, Nami & Chopper)
They have Stats of Top Tiers or Beyond, but when it comes to a Duel or Combat Skills, They aren't as Strong as People think
It's also possible that their Numbers are Reference to Thousand Sunny's Dock System, so They might actually be able to Fuse
That would result in a Very Overpowered Monster, but Separately, They aren't even above Seraphim
