Blair Wind
The Iron Avenger
Also considering that this is a big city, the battlefield works for me. I can use Crystal to create jetstreams along the streets to push back characters and disorient them, mixed with fire this would be really devastating. Also along other streets I could use other types of atacks like water, or earth dust storms, which would also have lightposts hitting his characters causing distoriention. Once DB makes his first set of dupes and is in control, I can move him into one of the buildings and use it as a breeding ground and set up camp along very many other buildings letting all my dupes rush into battle once their set up.
Also considering the fact that RM is on the ground and were around the buildings, Crystal and her army can create an earthquake making all the buildings collapse on him.
Really energy absorption makes most of Lp's attacks useless
my gravity makes most of his troops much slower,
my jetstreams will move him back, and mixed with fire it will have an added devastation factor
and I can set up breeding grounds with some stationary guards with a few Powerhouse and Crystal copies protecting DB's and their coping
and my earthquakes will make RM immobile.
