Dunno why people downplay Madara with Guy's feats. Juubito was easily reacting to Minato and tagging him. 8 gates Guy was a beast and Madara despite having a part of his body blown off simply regenerated. Juubito has the Truth Seeking Orbs, which were described as disintegrating everything on a molecular level similar to Oonoki's Jinton, while having the advantage of taking on any form, only weakness being Senjutsu. That's why Kakashi had to rip a hole into the shield created by Madara with Kamui for Guy to pass through, or otherwise it would have disintegrated him with physical contact, which means its effect goes beyond Ninjutsu.
In the Manga, Juubito was seen instantly putting out a barrier superior to the ones created by 4 Hokage, then instantly firing off 4 large Juubidamas while shielding himself with the Truth Seeking Balls, with the Barrier being strong enough to withstand the explosion.
Juubito would wreck any One Piece character.
This is what a small Juubidama looks like for anyone who has forgotten, being so large you can see the curvature of the earth, towering a hundred times over mountains, and Juubito can instantly utilize the power of multiple larger ones while having a perfect defense (360 degrees truth seeking balls shielding), which simultaneously acts as the perfect offense (disintegrating everything on a molecular level).
How does anyone think a One Piece character stands a chance.
