Slyvia is a monkey assassin mercanary that was payed by the bloons to track down and kill the Super Monkey. She is the main boss of Zone 6 in my conception of Bloons Super Monkey 3. But as well, after reaching Rank 75 on my conception of BTD6, she has a 50% chance to replace Hyurandi on Round 100 for Advanced Tracks. She has a variety of attacks that vary in each game.
