Another of my animal-related early comic characters... Here is ThunderHoof! He was/is the sentient companion to the superhero Boreas (kinda a blatant rip-off of Thor I know heh) but ThunderHoof was special in his own way... his mane, fetlocks and even his breath were formed of billowous fog/clouds that could be used for obscurin' him an his rider... plus he had the ability ta store up and magnify the kenetic energy he could use from his hoofbeats until he could release it into massive shockwaves that cause easily rupture the ground or kick down most barriers... :)
