As the title suggests, I've been searching for an anime I wanted to watch when I was in elementary. I remember it was on Toonami. Its plot is based on mecha-like anime, and the main character accidentally acquires a device that turns into a suit with a wolf theme and aura in the background, similar to Power Rangers.
The main character had no helmet; instead, he had white headgear. His suit was red with some white from head to toe, and his hair color was also red. The anime features other characters who have similar devices to the main character. I only remember that two of them had a three-headed snake and a bird-like mecha.
There were five in total, including the main character, working for an organization to fight wild monsters (I don't remember whether they were also mechas or not). The five were somewhere in their teens or young adults.
