Quote from ShadowSakura
code geass and death note have their own clichée
Spoiler (mouse over to view)
a high school student tries to get the world better with superpower they got and killd many people but in the end they die
and they are both spoken by Jun Fukuyama
But i like them. Even though i always cry
No, Lelouche is voiced by Jun Fukuyama. Light is voiced by Mamoru Miyano. No, it's not an alias.
And those aren't cliches btw. You showed two examples of high school kids that gained power and want to change the world. In shounen manga, the cliches are high school kids that gained power but get pulled into some conflict because their powers are "special" and now they have to defeat some evil organization from taking over or destroying the world.
