Loboans is very muscular, tall, has dog-like back legs, stands on his back legs, and has a face and muzzle that looks like a Mexican wolf's face and muzzle. It also has many animal-like tendencies.
In Ben 10: Evolutions there are a few slight changes about his body. His eyes are now green instead of violet and can grow quills on his back.
Loboans has enhanced strength, speed and agility; supposably being able to lift approximately 500 lbs and run over 70 mph. In addition to Benwolf's formidable claws, fangs, and muscles, he can emit a ultrasonic howl if the parts of his quadra-hinged muzzle is opened and a shout is let out. He can also do a jump attack by using his claws to slash the air.
Even being stronger than a human, its strength is still less than those of Fourarms. It can also be affected by many other normal attacks. Ultraviolet light may blind him. Benwolf is colorblind so it is hard for Ben to distinguish anything but black and white, it is only an issue when trying to figure out what is around him when looking straight on. A loboan finds it hard to resist animal like tendencies, such as hunting rabbits
