If there's someone I didn't put in, I either considered them irrelevant, forgot about them, or didn't know whuch category to put them under. And I'm listing the person's type where their strength comes out more than the others. For example, I'm pretty sure Beowulf is very powerful. But he's known for being a support-type and it stated that his true strength comes out when he combines his powers with his comrades.
