looks a bit nasty.
be 3 spaces away, shoot, if you hit step in, brawl, if you hit they get tossed, then you run 3 spaces away.
let's say you toss the opposing monster onto a building with a hazard, that's 4 damage in a turn, barring any inconvenient skills. throw in spire or hit more than one building and you're really coking with gasoline!
I like it. somewhat gimmicky, versatile if you don't go for both of the attacks.
how does he seem? balanced? unbalanced? personally, I think he's pretty balanced. 4 speed without enough power dice (but when have martians ever had problems getting power dice?) HURTS, even with climb! and you'll be using those power dice to pull off the blast portion of your activation with such a low blast stat.
I want him.
