A Tank Toppler is a large, nearly spherical, bomb-like Unversed. Its upper body is pitch-black and its lower body is navy blue with red stripes. The two sections are divided by a red stripe around its waist. Its head is spherical with a tall antenna resembling a wick on the top of its head. Its head and the area around it is navy blue, and the area around its head has a red outline shaped like an eight-pointed star. Its arms are very short, nearly spherical, and seemingly useless. Their tips are silver and sport a short, silver rod. There is a golden valve on its upper back. The Tank Toppler's red eyes are set in an angry expression and a large Unversed emblem adorns its chest. It has been shown to inflate and deflate at will.
Tank Topplers are sturdy enemies, and can be a bit of a challenge to defeat if one does not use the proper strategy in order to do so. If these Unversed are hit from the front, they will glow red, swell, and finally become immune to damage for a period of time before exploding. In order to prevent this from happening, it is highly recommended that the player strike these Unversed from behind. Tank Topplers can also attack players by bouncing on them, or shooting gusts of air from their arms.
- Bounce: Bounces around trying to land on the player.
- Air Blast: Shoots gusts of air from its arms.
- Air Dash: Flies around, hitting the player.
- Self Destruct: If attacked from the front too many times, it will glow red, swell, and finally roll around, immune to damage for a period of time before exploding.
