Of course, there was the "Julius Kingsley appearing as Lelouch vi Britannia" comparison. HOWEVER- that wasn't a comparison between two separate characters, but the basis of a theory that suggests how Julius is actually Lelouch who had been brainwashed by Charles and..... anyways, you get my point (hopefully).
Though, after 170 (or so) animes, this fact that I've never compared characters together now stands to be corrected. And it all started with watching Mahouka Koukou no Rettousei (The Irregular at Magic High School).
For those who are familiar with both this anime and Code Geass, I'd have to say that the moment I saw Masaki Ichijou in the OP:
Wonderful. Is this a sense of foreshadowing that I'm getting from some otherworldly anime force? (no, it's actually just my brain's desperate attempts to make life seem more interesting)
Because let's be clear about a fact first: I really, really dislike Suzaku. Really dislike him. (To all the Suzaku fans, no you do not get an apology from me). If you were to ask me why I don't like Suzaku, I'd tell you I would have needed to spend all day- but I'm pretty sure that I've already raged about him before when I saw him in Boukoku no Akito, Episode 2.
So, perhaps I'll also be inclined to dislike Masaki too? Hmm, from the way episodes have been progressing in Mahouka, I probably won't end up liking him. However, I doubt that he's going to get on my nerves as much as Suzaku does.
