You won't find anything like that from my Avenger. When it comes to ideals, he's staunchly against them. Maybe you could even call that an ideal of his. When it comes to passions - I wonder if he has any? Well, he likes Godzilla. . . ?

When it comes to "things he would fight for", it would ultimately just be to save his own life. Well, he would fight to protect his Master too, probably, but only if that person agreed to such?

. . . In the first place, the nature of his existence should not afford him something to "care" about.
