Plants vs. Zombies: Siege of Zomboss/Bosses

This is the list of bosses in the game, which have special abilities that mow down yo plants! Also, all of the bosses summon zombies from the right of the lawn, except for the Zombot Gem Galleon, which summons zombies through boards that randomly get thrown over to the lawn, The Final Zomboss, which summons zombies through teleportation, and Giga-Football Zombie, which doesn't summon any normal zombies at all.
