Honestly, in my case, the first Leonardo that I admired was the turtle ninja Leonardo since I loved that series as a kid haha :D I think you are of a similar age like me so I´m sure you know that series too :) Later in my life, however, I found out who this turtle ninja was actually named after :D Yeah, da Vinci is and will always be one of the greatest and most versatile geniuses who have ever lived on Earth :)
