Strategies
He is classified as a Giant Robot, but is till vulnerable to backstabs, has much more health and is normal size.

He should not hit you with his syringe gun or he will restore health on hit.

He cannot arc his syringes due to his AI but can still shoot you from a medium range.

Stages

 * 1) He starts off alone and fights you with his syringe gun, killing anybody close enough. (NOTE: Don't try to corner him, also for some unknown reason, this last stage has significantly more health than the rest.)
 * 2) He heals a Titan Demoman and will heal him with the Kritskrieg. Once he has Ubercharge, he will momentarily increase the Damage of the Demomans "Nuke Pills" and will destroy anybody close enough to the projectile. (NOTE: Try to destroy the Demoman first, then him, he does not have a way to protect himself, only once in a Blue Moon does he use his syringe gun.)
 * 3) He heals a Titan Scout with the Quick Fix. Once he has Ubercharge, he will momentarily have knockback resistance and will instantly bring his health and his pockets health back up to full. (NOTE: It is important to destroy him first then the scout)
 * 4) He heals a Titan Heavy with the Stock Medigun. Once he has Ubercharge, he will become invulnerable to any form of damage. (NOTE: It is easier to destroy the Titan Heavy first, for some unknown reason, this last stage has significantly more health than the rest, once the heavy is dead, he will pull out his syringe gun and will do the same amount of damage like the first, but he does not retrieve health back.)
