I thought the coolest abilities were the evolved forms. My personal favorite is the Biological's Predator Form, especially with its 100 focus regeneration per turn.
OK so Wraith form for me is the best, with the increased speed, means higher burst damage (piercing) electro bolt + wraith = 7000+ critical hits.
I've tried out every other form and i would have to say my second favorite is the guardian form. because guardian form + ice wall, and 20,000 (around 600 in vitality + android armor) = 1 damage per turn.
with the combo forms, I feel that biological's is the best because of toxicant form + predator form which couples to around 10000 damage in one turn, this is also achieveable with psychological, but the build is really horrible because you end up losing 600-700 hp a turn
