I don't know about you guys but does basing your minis sap your creativity, too? I hate having to do it.
Left: Khurasan Mantis, Right: GZG 6mm Bug
The "kermit-green" fellow on the left is going to be a Mantoid, a warrior breed of bug designed to complement the Formians who comprise the bulk of the bug's line infantry. Mantoids are fast, deadly, and motivated by instinct. Their predatory nature makes them great for use as shock troopers since they can operate ahead of the main force without needing to rely on contact with command for orders or resupply. Furthermore, they don't share the trademark weakness of Formian infantry in that they do not require a "brain bug" NCO to maintain unit cohesion.
The little critter on the right is a Mite. They are the guard dogs of the bug armies and serve a number of functions. They can aid in an assault, they can sniff out bombs or non-insect creatures, and they can dig small tunnels and holes to aid frontline infantry. Truly esteemable little creatures... assuming you're a bug. Otherwise they are foul, carnivorous pests!
