>>10698055There's like 25 years of Lore, alot of older stuff has been retconned or adjusted, but having followed the lore for a long time now, there are definitely trends and rules followed.
A Daemon prince or Greater Daemon bodying marines is definitely standard. To the point where people in the hobby accuse the character of being mary-sues if they hold their own or win against them. Not to say that *groups* of Marines, Grey Knights / Custodes don't win against them, but it's always at cost. In one of the most recent books detailing the Lion's return, Dante and his Honor-guard are casually bitch-smacked aside and almost totally wiped out by Angron. Dante is the single greatest space-marine hero in the setting(not the strongest, but probably the most noble and accomplished). It takes 100+ Grey Knights or a top-tier duellist loyalist Primarch like the Lion(I don't think G-man could do it) to deal a Banishment to Angron and now this motherfucker gets to come back in weeks instead of hundreds of years.
