Just because i shinobi isnt top 10 material doesnt mean they're a fodder, they may look like fodders compared to obito/madara but thats just because of how powerful they arebullying a bunch of fodders, thats really badass
Obito's kamui speed is demonstrated this chapterNew tech from Obito...That is about it. That is something that I would have expected from Madara. I don't think anyone underestimates them, people just bash them because they are the bad guys and well...eventually they will be defeated.
Also, thats the largest katon technique shown in the manga, look at it compared to the juubi too.
