OP is incorrect about several things. 1. Killing ANY boss at least once will cause him to spawn from then on. 2. You only EVER need to kill one boss. Killing bosses after he shows up the first time doesn't 'reset' him, or increase the chance for him to spawn. 3. He can show up in ANY mission. Tower, regular defense, or nightmare. 4. The number of missions you do is irrelevant. He can show up in 3 missions back to back if hell feels like it. Or he can show up once every 50 missions. It's TOTALLY random.

Just wanted to dispel some misinformation.
