Alternate Special Unit Brain Storming

[AJaW96]

In the money raising thread I touched on the idea of OML selling alternate special units for the Scallywags, Feedback, Adorables and Veggienauts to help raise revenue. This idea then had me thinking of all the possibilities for alternate special units. If you could decide on this, what would you create?

To help get the ball rolling, please see below.

Volleyfin
Scalleywags
A pirate puffer fish that can launch a salvo of needles. A sniper with 2 health, 2 range and 2 move but with a twist. It will only do 2 damage per attack, but it can make as many attacks as you have wits.

Teleporter
Feedback
A robotic assassin with a wicked knife. A soldier with 3 damage, 2 health and the ability to move regardless of walls and holes by teleportation.

Angel Bee
Adorables
A cute bee but with angel wings and a halo. A 2 health medic but with 3 range.

Leaf Cutter
Veggienauts
A wiry root with a large sharp leaf coming out of the earth. It can only move by teleporting to empty spaces next to other Veggienauts units.

What does everyone else think of the idea and what units would you make?
