PLUS Loan Interest Rates. Interest rates on Parent PLUS and Grad PLUS Loans are the same. Students attending graduate school and professional school were first able to borrow the Grad PLUS Loan in the 2006-2007 academic year.
Neptulon is the strongest Elemental Lord, Al Akir is the weakest. Ragnaros was never killed just banished back to his realm, the Fire lands, any multidimensional being is generally beyond the ability of mortals (us the players) to truly kill a permanent kill.
Nazo in his base form is stronger than super shadow, in his perfect form (all he needs is the 7 chaos emeralds) he is way stronger than HYPER form! If Nazo is really as strong as you say he is, then he's literally the most powerful character that has ever interacted with anyone from any Sonic universe ever.
