Naugus

Naugus is a new hero in Thermoxin's Bloons Tower Defense 7. He can crystalize up to three bloons at the speed of a 2/0/0 Alchemist Monkey, which pops 1 layer and freezes them in place for two seconds. If crystalized bloons have the lead property, however, the bloons move backwards and attack other bloons until all of its layers are popped.

Levels
Naugus will start upgrading himself every round upon placement. He earns more XP each round to unlock his next upgrade irrespective of how many bloons he pops. His upgrades can also be immediately bought with cash, though the amount of cash required to purchase the next upgrade will typically increase as the upgrades get higher, making self-upgrading an important element for his overall power.

The following are the upgrades and their costs of upgrading without XP:
 * 1) Naugus is a powerful crystalmancer, a power he uses for his own benefit.
 * 2) Attack speed increased by 10%.
 * 3) Unlocks Posession.
 * 4) Hypnosis - Naugus can hypnotize one tower within his range at a time, which gives them the effects of a 4/0/0 Alchemist Monkey 's buff. He will automatically target the tower with the most money spent on it. If another tower has more money spent on it, Naugus will switch his hypnosis to that tower, immediately ridding the other tower of its buffs.
 * 5) Range increased by 10% and gains camo detection.
 * 6) Crystal Spikes - Spawns a cluster of spikes underneath the strongest bloon on screen every 7 seconds. This cluster is the size of a 0/0/1 Ice Monkey 's range, has infinite pierce, and deals 15 layers of damage.
 * 7) Initial crystalization deals two layers of damage.
 * 8) Five bloons can be crystalized at once.
 * 9) Hypnosis can affect two towers at once, while still targeting the towers with the most money spent on them.
 * 10) Unlocks Crystalline Slave.
 * 11) TBD
 * 12) Crystal Spikes triggers every 5 seconds, and deals 25 layers of damage.
 * 13) TBD
 * 14) Hypnosis can affect three towers at once, and has unlimited range!
 * 15) TBD
 * 16) TBD
 * 17) TBD
 * 18) TBD
 * 19) TBD
 * 20) Crystalline Spell can affect Z.O.M.G.s and D.D.T.s, and lasts for 20 seconds.

Activated Abilities

 * Posession - Posesses the strongest tower nearby, fusing their powers together. Attacks have benefits from both Naugus and the tower currently posessed. The posessed tower can not be upgraded during this time, however. Lasts for 7 seconds, and has a cooldown of 30 seconds.
 * Crystalline Slave - Casts a powerful spell on the strongest bloon on screen (not including the Z.O.M.G., D.D.T., B.A.D., or D.E.A.T.H.), and causes it to reverse direction and attack all other bloons in its path. Lasts for 10 seconds, and has a cooldown of 45 seconds.
