Hi Steriaca,
I think you made a typo on the cost of the characteristics. A speed of 5 would cost 30 points and an endurance of 55 (rounding off...) would cost 7. My total for the characteristics was 249 but I did it by hand.
As for the two multipowers, they look fine as far as I can tell. I have a couple of suggestions:
For the power transfer gauntlets should the drain/aid effects have a time adjustment? The way it is currently set up Power Crusher would lose 5 points per turn. Personally I would move the effects down one or two time increments.
The original Power Crusher could also drain/aid Dex and Speed. Clearly that's up to you. Given that he needs to grab to make the drain/aid work, strength is clearly the critical characteristic for the build.
In the original build to do a 12DC attack he would have to transfer a fair bit of strength first. If the gauntlets are the source of the power transfer does it make sense to charge endurance for the powers? Perhaps, in your version, the gloves also have an endurance reserve?
Looks good!
