El Tigre, or El Tigre II is the half superhero and half supervillain form of Manny Rivera. As such, El Tigre is what most of the show revolves around.
Manny has used his El Tigre powers to be a hero to stop supervillains but has also committed evil deeds such as teaming up with other supervillains to cause destruction and havoc. Besides Manny, an ancestor of his was called El Tigre I who also had the same powers Manny has in the current timeline of the show.
While the initial conception of the mystic El Tigre Belt remains a mystery, it is clear that it has been around far longer than earlier Mexican civilizations, likely older than even the Bronze Boots of Truth. The difference of the belt from the other two objects of power, is that the belt buckle needs to be spun to be activated, unlike the boots which give power by merely wearing them, and the sombrero, which can be used on mental command. It is also quite obvious that the belt is far more power and harbours a much more powerful spirit inside of it, the Ancient Tiger Spirit. The fact that the belt must be worn and the buckle must be spun as well is likely the only way of holding back the power of the belt. The only other wearer of the belt was around far before any of the other Rivera's, seen as the first Rivera, dating back before/during the Mesoamerican era, so it is safe to assume the belt was conceived around this time.
The actual purpose of the belt could be observed rather well. In Aztec mythology, the current universe that which they (and we) lived in was the universe of the Fifth Sun. In one of the many Aztec myths of Afterlife, those that had not done their rightful duty during their living, would have their souls torn apart by a ravenous tiger. This was likely the inspiration of El Tigre's powers and the Ancient Tiger Spirit, as El Tigre had power over both the land of the Living and the Dead, and could travel between both, likely to do the part of the Tiger Spirit and punish those who had not done their duty to the world or wronged others.
Manny's physical appearance doesn't change a lot when he's El Tigre. His brown eyes turn green and he gains a tiger tail.
He wears a brown mask that has white furry sideburns, tiger-like ears and a letter "T" on the forehead. His suit is completely black with red stars on his gloves, brown boots, a red bandanna on his neck and gray metallic claws. His belt remains the same.
