can chemo use slippery? and since it does require a roll, can it be used to trigger shake-off?

as near as i can figure the answer would be "yes" but i want to make sure.

Chemo doesn't fulfill the prerequisites for Slippery (Combat Reflexes, Defend, or DV of 18 or more).
However, I guess Slippery and Shakeoff would be a valid combo... Why not try it with Colossal Boy?

I'd go with Shake-Off + Armor Piercing on Chemo. You deal penetrating damage to all adjacent figs at the beginning of your turn, and if your break away roll is successful, you deal an additional click of penetrating damage.

Armor Piercing doesn't fit the bill for Penetrating Damage as defined in the DR PAC preview. AP simply prevents Damage reducing effects from reducing the damage dealt to less than 1, while Penetrating damage can't be reduced by powers or effects that reduce Damage Dealt. I realize in your example the distinction is irrelevant, but for most other situations it is.
