The Doc now has his support ability, Steroids, which, I've said before, raises the attack damage of a friendly organic unit, but damages that unit as a side-effect. The effect lasts for 2 turns and you can stack it.
As usual, the work-in-progress, playable demo is available at http://anomalousunderdog.herobo.com/Unity/DZZPrototype.html
Weird thing is he can raise damage of a unit even though the guy uses a gun to attack. Then again, the Marine of Starcraft also uses a similar idea with their Stimpack ability, and they use guns too.
