The Highbreed Commander's Mothership is the spaceship of the Highbreed Commander from Ben 10 Returns Part 2. The ship itself is around 100+ft tall. The engines are able to cut out mid flight to convert into a large laser cannon which the Highbreed Commander attempted to use to sterilise (destroy everything within a 5 mile radius) the area. Luckily Ben as Humongousar was able to destroy the ship after hitching a ride. Luckily Ben as Humongousaur was able to down this ship by punching a hole in it. This cost his grip however causing Ben to fall roughly 1000 ft, but thanks to Humongousaur's tough hide all Ben suffered was a scaped leg. The ship, including a crew of DNAliens and one Highbreed Commander, were lost in an explosive resulting from the ship itself falling from that height.
