A favorite? Well It's a list, like my top 5 they are Dragon Ball Z, Yu Yu Hakusho, Sym-Bionic Titan, Fullmetal Alchemist (original), and Yu-Gi-Oh! I chose FMA original over brotherhood because I liked the way it took it's own direction with the anime

Yu Yu Hakusho, Rurouni Kenshin, Digimon, Darker Than Black, Kurokami, Code Geass, Anything from the DC Animated Universe, The Batman
