To improve the Ulmanator's top speed, Ulmar removed all unnecessary components from the vehicle. Unfortunately, that included the brakes
In the Animation, right in the very first episode of the Secrets of the Lost City, Ulmar gets out of his comfort zone for a more social interaction — and to show off with his Ulmanator — as one of the competitors of the Perithon, the huge racing event across all of Perim through different territories of all Allied Tribes to celebrate the victory over the M’arrillians. Comes into play, the Perithon Racer.
At first glance, the Perithon Racer might not seem much of an improvement being mildly more power and resilient but, looking beyond the deception, Ulmar becomes a renewable and virtually limitless source of damage, just needing to rest for a bit until fire up his UnderWorldly flame. And if that’s not enough, as long as he doesn’t make them sentient (again), he can still wreck enemies with a Gigantroper.
