I hope I'm not necroing or anythying but I'll put up an opinion. If this is Cole Macgrath vs Crackdown 1 Agent then COle would stomp.
But if this is Crackdown 2 Agent and the latest Cole then I might give the edge to the Agent. Insulated armor would nullify most of Cole's electric based attacks besides the Lightning Storm. Ice powers are nifty but the Agent can get out of it easily with his thrusters and wingsuit (flight).
Then the Agent has his Mass Driver that would lift Cole up and prevent him from moving. With a well placed quacker or flocket launcher Cole will get blown up to bits. It'll be worse if this is Evil karma Cole since his fire attacks will be useless against the fireproof Agent.
