Random Kill Team

 A fun little group made up of various minis.

The Guyver

 Bio Booster Armor.

Combat Zone - Corpo Troopers

 Troopers from em4 Miniatures, older miniatures that have found a new lease in life as part of their Combat Zone range.

The Terminator

 Sarah Connor?...

RX78-2

 My local comic shop had an open build day, where they gave away basic entry level Gundam kits. I decided to have a go at a rusted damaged look.

Alternative Armies Rebels

 Random space troopers.
