After painting the Nexu for Imperial Assault, I decided to rebase the miniature (or all my Imperial Assault miniatures), as I am not a fan of the supplied flat bases.
Specifically, I used Games Workshop’s Citadel 50mm round bases, identical in size to the Nexu-bases from the Imperial Assault box, and made simple, unobstrusive grey bases with sand painted with a base coat of Skavenblight Dinge, a dry brush of Administratum Grey and some green Games Workshop flock.

The most difficult part by far was to get the Nexu off their old bases.

Fantasy Flight Games‘ plastic can be surprisingly tough to cut through and file off the miniature. The process even murdered my old Citadel clippers, after which I switched to proper tools to get the Imperial Assault Miniatures off the old bases.
