Gravelord Bloonarius

Gravelord Bloonarius is a Boss Bloon in Bloons TD 7 that was introduced in Version 28.4. It is the fourth Boss Bloon to be in Bloons TD 7. It works similarly to both Bloonarius and Lych, with resurrecting fallen MOAB Class Bloons, going invisible and spawning a Lych-Soul, spewing and scattering Bloons, however, it also moves at the speed of 1.2, higher than any Boss Bloon besides the DOOM Bloon. It also saps buffs from your towers, as well as healing when towers are sold. Further revisions were made in Version 29.0.

Properties
Gravelord Bloonarius is noticeably faster than every MOAB Class except the DOOM Bloon and the DDT, however, it also has extreme health, and has many gimmicks. The normal bloon spawns on each Gravelord Bloonarius spawn round are modified. Round 40 has 6 Ceramics (as opposed to 1 MOAB), round 60 has 6 MOABs, round 80 has 6 BFBs and round 100 has 18 DDTs and 12 ZOMGs. For every RBE, it scatters some bloons, and when every skull on the bossbar is reached, it spews bloons, becomes invisible and invincible, reanimates fallen MOAB Classes, and summons Lych-Soul.

Visual Appearance
It looks similar to Elite Tier 5 Lych's sprite, but also has swampy details on the sprite. The sprite has more fins, and more chains the the regular bosses. It also creates a green aura, similar to a 3-0-0, 4-0-0, or 5-0-0 Monkey Sub. It also has an open space with a propeller, similar to Bloonarius.
