Linebacker

Leonardo (レオナルド, Reonarudo), better known throughout his kingdom as Linebacker (ラインバッカー, Rainbakkā), is a Frontliner (最前線者, Saizensenmono) of the Celestial Kingdom and one of the strongest individuals the kingdom has to offer. He is also the captain of the kingdom's Defense Division.

Appearance
Leonardo is a man of average stature, as revealed in his own profile, standing at a height of 175 centimeters. His usual attire consists of casual clothing, which is normally an unbuttoned black trench coat with a plain white shirt underneath it. His lower half of his body consists of a pair of ripped grey jeans and formal black shoes. On the other hand, despite his rather average stature, he is considerably muscular. While assuming Leonardo's personality, both of his eye pupils are red-colored.

As Linebacker, his physique stays the same. However, his appearance changes drastically. A playful and rather childish man he is, his attire consists of a crimson robe and a hot pink sash. His lower half of his body consists of a pair of simple yellow trousers and a pair of wooden clogs.

Though this is quite rare, as he(both personalities) usually slacks off and doesn't participate in most events, when attending an urgent meeting or when his kingdom is under steep situations, he dons the traditional uniform of a Frontliner, though he decorates it exaggeratingly with jewelry and badges in a comical attempt to look cool.

Natural Abilities
Excessive Strength: Despite his average stature, which makes his opponents to greatly underestimate him, Leonardo actually possesses an excessive amount of physical strength, as noted by former chairman of the Magic Council himself when discussing about the threat the Celestial Kingdom poses to the Magic Council if not taken care of, referring to each of the Frontliners as "true beasts in terms of physical strength". As he himself had explained, he spent the last three years on physical conditioning, with his strength training routine including a thousand punches and kicks underwater a day, dragging one hundred heavy boulders a day, a thousand punches and kicks to a steel pillar a day and to top it off, all of this is done with only a few breaks, which includes his eating and sleeping time. As a testament of his strength, the prime minister of his kingdom sent him to deal with the blocks of the palace exits that consists of about five hundred boulders that the invaders placed, and with almost no effort, it took him one punch for each exit to clear the path.
