The Guardian Star summoned his mount, making Eren see another new species of this world which he hadn't seen before.
It was an infernal beast that resembled a fusion of a dragon and a colossal wolf, with skin beneath his scales that appeared like molten lava.
Its scales are a deep obsidian black with glowing veins of crimson and gold that appeared to be alive. Its eyes were filled with darkness, sharp like a demon waiting to devour everything in its path if offended.
On its head were two curved, obsidian horns that arched back, accompanied by a unique crest that looked like it had been carved on the horns with a material even harder than the horns.
Though primarily a ground beast, the Infernal Beast possesses wings that could unfurl to glide over short distances or to leap great distances.
Eren had to avoid the tail of the beast which had sharp spikes coming out of it. He was sure that if it touched it even lightly, it was going to hurt real bad.
