Description
The Tracker is an enemy only encountered in Ultra Nightmare Mode, debuting on Wave 25 with highly increased 
health and 
shield.
Upon its debut, it spawns along the Aerial Juggernaut, having bolstered health and shield, making it a dangerous threat for low-DPS defenses. Tracker also has an ability which makes it stop in place and shoot a tower with a yellow laser. Despite being an intimidating ability, it deals barely any damage with a low damage penalty.
Appearance
The Tracker is a large humanoid with red skin and clad in metallic armor along with a headset.
It wears metallic boots with rising brackets that reach to the upper shins. The legs are covered by reddish-brown pants. Its waist is covered by a belt with a red pocket and gray accents on its bottom, along with having a spare piece of metal in-between its legs. It wears a brown shirt which is under a metallic chestplate, with a under-part on its middle and two slightly extending parts on its right and left. A small square-triangle fusion with three red dots is on its right, with three black slits on its left. It also wears two black pauldrons. On its head is a headpiece with extending goggles with a protrusion on its top, having a yellow tinted eye-pieces. On top is a small "box" with a red dot, and a grip extends around its head, which is bolted down with two large dark-white nails. On its back is a mechanism with a slight dip into a lighter gray pool with two red dots. A protruding box is on its right, having a red range-field like mechanism, with two dots and two sloping lines. An antenna and three paired yellow wires are attached to its back, with one of the three wires having black tape. Another wire sticks to its head.
