Honestly, I think Naruto would handle him with mid difficult. If you threw Naruto into D Grayman, he would be around the level of a General.
@JThree47605: how so? oh, and allen is also technically general level since his battle with tyki.Unleashed Tykki tore a whole in Allens ass, and I wouldn't put Allen at General level quite yet, Level 4 Akuma always gives him hell, most Generals could one shot L4 Akumas. The real reason I'm giving this to Naruto is because of the Nine Tails I just don't see Allen doing a whole lot of damage to Naruto
@YouFinished: BTW did you like apostille?sorry but wha?
