The Master of Bloons, H.A.D.E.S.

H.A.D.E.S. Lord of Chaos and Death
No greater bloon exists, he is nearly invincible and is capable of wiping out entire monkey cities. Given the nickname "The Bloon from Hell" by the monkeys, this is one bloon you don't want to make angry.

(for his story, see Endless Bloons Tower Defence)

Statistics
H.A.D.E.S. has 3 different forms, which he switches between after taking a certain amount of damage

Flame H.A.D.E.S.
Flame H.A.D.E.S. (to the right) is his original form. This is actually his fastest form, moving at the speed of a Lead Bloon. It has 10,000 health, less than D.I.A.B.L.O. but it does have some cool abilities.

Spawn: Every time H.A.D.E.S. is hit, a pink bloon spawns where he is, but this cuts his speed in half for 0.2 seconds

Nether Gate: Every 30 seconds a BFB comes enters Morph: After taking 10,000 damage, he moves backward on the track for 5 seconds, then he transforms into his next form

Shield H.A.D.E.S.
Shield H.A.D.E.S. is the second form. In this form, he moves at the speed of a ZOMG and has 100,000 health. His abilities are all passive in this form

Sonic Pulse: Every 200 damage he takes, he disables all towers' camo detection for 3 seconds, and spawns a camo Lead.

Deflect: Every 5 hits, his shield deflects an attack

Morph: After Taking 100,000 damage, he he moves back to the beginning of the track and mutates into his last form

Shadowborn H.A.D.E.S.
The final, strongest form of H.A.D.E.S. Born from pure rage and greed, his power is nearly infinite. Only a true warrior will have the skill and bravery to Defeat him

Shadowborn H.A.D.E.S. has 5,000,000 health, making him the strongest bloon in the universe, but his speed is half that of a VANBOED. His abilities are unique, but he doesn't morph

Hostility: Every 50 seconds, it destroys your cheapest tower

Arial Assault: Every 75 damage he takes, he summons 20 camo lead bloons. However, he freezes for 2 seconds to do this

Demolition: Every 10 seconds he is alive, you lose a life.

[Passive] Extremeness: Anything that slows down bloons has no effect on him.

[Passive] Singularity: All physical attacks (darts, bombs, etc.) get sucked into the black hole and heal him by 1 health per attack

Rewards
If you are somehow able to defeat H.A.D.E.S., you will be rewarded with 5,000 bloonstones and 1,000,000,000 exp. You will still be able to play the game, but you can only fight H.A.D.E.S. if you have beaten a track in every difficulty, you can then fight him again there. But, he will only give 100 bloonstones and 100,000 exp.

Note: Beating H.A.D.E.S. will automatically make you exit the track.
