Vault of the Gameverse says, "While fighting regular groups of enemies, Captains can show up at any time which is super cool. I’ll be in the middle of this huge war, destroying twenty, fifty, seventy enemies and just when I’m enjoying being a complete badass, some Captain will come in and slap the crap out of me. Then, I’m facing a huge army of common enemies with an all new boss type. But that’s not all, often times in larger battles, more than one Captain will show up. It’s nuts."
