Humanity is under attack by a different live form that threatens humanity's existence, be it angels in Evangelion or devils in Devilman, and the wussy main character is the humanity's chance of winning. In Evangelion, he gets forced to get into a mecha and fight, while in Devilman he gets forced to permanently turn into a demon and fight. The ending is similar, and in fact Evangelion was inspired by Devilman, but I won't give too much details as to not spoil it.
