Leonardo Watch

Leonardo Watch is the main protagonist from the Blood Blockade Battlefront anime and manga.

Leonardo is a photographer who came to Hellsalem's Lot to help his sister, Michella Watch. Upon visiting Hellsalem's Lot, an entity known as Riga El Menuhyut gave him the "All-Seeing Eyes of the Gods" at the cost of his younger sister's eyesight.

Appearance
Leonardo is a young man with disheveled brown hair, wearing a blue and white baggy sweater, wearing sneakers and wearing orange googles which he wears from time to time.

Personality
Aside from his eyes, Leo is a decidedly normal young man and can be somewhat of a coward, easily intimidated by the bizarre nature of Hellsalem's Lot. Though, he bears an adventurous and courageous side as well, growing less cowardly as he gets used to his new home. He tends to express his emotions openly, whether they be excitement at something new and enjoyable, fear of the insanity and dangers of Hellsalem's lot or annoyance at Zapp's negligent and irresponsible attitude. Guilt-stricken that he was not courageous enough to speak up and prevent his sister's sight from being taken away, Leo is determined to uncover the secrets of his All-Seeing Eyes and try to find a way to restore his sister's sight.

He is a very kind person, as he works very hard to earn money to support his sister but refuses to be paid by Libra more than he feels he deserves and takes a second job as a pizza delivery man to cover the fees. In addition, he quickly becomes friends with a mushroom monster in episode 6 despite the common prejudice humans have towards monsters from Hellsalem's Lot. He even offers to meet him at a specific time any day he can to buy him burgers as his friend had been conned and forced to pay quadruple the amount of money needed to pay for the soda since monsters weren't allowed into the burger establishment.

While he lacks the combat skills of his fellow Libra members, he is quite clever and quick to adapt to situations. Michella fondly calls him her "Tortoise Knight", because Leo never runs away even if he freezes up and cannot move, even if he is at a loss, and will endure until the moment he can take a step forward.

Despite having the powers of the All-seeing God's eyes, he refuses to abuse them for his own benefit. When an arrogant tourist beats Leo and takes his wallet, Leo refuses to use his eyes to attack the aggressor. Leo later tries to confront the aggressor with nothing more than an electrical katana which would not kill the man but only hurt him (despite having access to a large number of weapons that could've easily killed the man), demonstrating Leo's pacifistic nature and kind heart.

He is usually partnered with Zapp Renfro, and is typically forced to put up with the man's shenanigans, often voicing his displeasure towards them.

Abilities
All-Seeing Eyes of the Gods (Kamigami no Gigan): An artifact implanted and given to him by a mysterious entity at the cost of his sister's sight. He has heightened visual senses, allowing him to see fast movements normally impossible for human eyes to follow, or minute details with great clarity. The eyes are also equipped with a self-restoration function such that over time, they will heal themselves of any damage sustained.

Most importantly, his eyes see 'The Truth' of the world. This allows him to see past world altering illusions along with perceiving an individual's unique aura. His eyes are especially effective in identifying the scarlet feathered aura of a Blood Breed. Upon staring at an Elder Blood Breed for a duration, he is able to see their "true name", but only if its heart is present. Leo can also manipulate the vision of others, including that of machinery such as Aligura's monster truck, and force them to move in the direction he wants them to, or see through another individual's eyes and even witness past events that they have seen. He is also able to use his eyes to track the individual aura of a person as mentioned in episode 2 of season 2 and fully shown in season 2 episode 5 where he was able to find Philip's brain and track it by matching its aura with Philip's aura.

Using the power of his eyes however has its limits, as they overheat upon prolonged use of their abilities.
 * Plain Eyeballs (Hira Gankyū): Leo induces nauseating hallucinations on his opponents. In the manga, this technique is unnamed and Leo simply commands his opponents' eyes to obey him.
 * Vision Transmission (Shiya Tensō): Leo projects what he sees into the minds of others, effectively sharing his sight with them.
 * Vision Shuffle (Shiya Konkō (Shaffuru)): Leo alters the vision of those around him by shuffling their field of visions.

Trivia

 * The Blood Blockade Battlefront Official Fan Book B5 states Leo's height to be 161 cm, or 5'3".
 * Leonardo is a young adult, given his ability to enter bars, and in the official art for the DVD/BD box set design for Animate, and many other art promos, Leo is shown drunk, and or in a bar. His short height and baggy clothing, however, make him appear younger then he is, making him the butt of "too young" jokes that he blatantly ignores. He does however acknowledge it once in the anime, in episode 10.5, when the radio show host mistakes him for a student, but Leo corrects him and says he is an officer.
 * It was later revealed in the Blood Blockade Battlefront Official Fan Book B5 that his birthday is May 14th, making him a Taurus.
