Hopping any efect thats grants him the ability to transfer damage to higer points Metal Men.

Where's the Mastermind to any Metal Men definition? Eratta!

Oh yeah, that's a gross omission from him. On Metal Men teams, he cannot Mastermind to ANYBODY, since the cheapest Metal Men are at 25 points, and you can only transfer to lower point characters.

I pulled one that had a Hitler stache, is that normal??? Needless to say, Doc Hitler will be on my Hydra teams.

has been discussed extensively in another thread - we're hoping for a zero cost ATA for Metal Men which allows them to treat other Metal Men as lower cost (either for Mastermind, or for Leadership, or just ... lower cost for any purpose).

I absolutely love the metal men, but Doc's mastermind is completely worthless, and I'm very upset about it :(

Normally when I see mm on a figure that costs 50 points or less I think it's a waste.
This is no exception.

Doc Magnus + Tin/Mercury = Support piece with healing minimum of 2 for 50pt. Also, no mention of unique modifier here, so could he get up to max healing without even making the d6 roll? Just a thought.

Regardless of how many Metal Men are near Doc Magnus, he would only get +1 bonus for the healing. When using support, there is a minimum, but there is no maximum. Doc Magnus still has the potential to heal for 6 clicks. Crit Hit (+1), Roll a 6 (+4), and near a Metal Man (+1).

Obviously he's built for his theme, but Mastermind now allows him to treat not only his Metal Men but any Scientist as a Mastermind soak - and he can then heal them for their act of loyalty and sacrifice with his Support! Altogether, 25 points is ok for a decent healer who can hide in cover and not get punked.
