Fanon:The Mad Doctor

The Mad Doctor is one of the Lesser Sons that can spawn near the Fortresses as miniboss. Created by Kacperlupa.polska.

Design
The Mad Doctor is a bigger Injector, but he also has two barrels on sides of lance. His liquid constantly changes colors.

Attacks

 * Injection: He quickly charges at the tank and gives it Slowed, Poisoned or Blinded for 5 seconds.
 * Pills of Doom: Shoots out ovular bullets that deal big damage despite being, well, not quite big.
 * Medicine: He gives himself Hasty or Strength for 20 seconds. Has a 1% chance of giving Invulnerable.
 * Unstable Substance: He shoots out color-changing bullet that explodes after 1-3 seconds or contact with anything.
 * Experiment #538: Spawns a big durable green minion that changes its type every 5 seconds. Can be:
 * Smasher with two Battleship spawners,
 * Twin Flank with one barrel instated of two on one side,
 * Hunter with trap launcher on back.

Trivia

 * Yes, yes, it only truly uses his lance during one attack, but couldn't find a better attacks that fit that 'Mad Doctor' theme.
