As others have already countered the rest of Dai Blackthorn being less realizable in HERO than in GURPS, I'll go for the one left as yet unanswered.
Honest Face is probably not a Hero trait.
There are
a variety of ways to handle this in HERO- a PRE or COM bonus (possibly with limits like "Only with _______ skills), extra points spent in particular skills, skill levels with the limitation "only usable with PRE & COM based skills," a limited PRE or COM based attack or even a very small and limited Elemental Control.
As for:
In HERO terms, he's already bursting at the seams in terms of PsychLims.
...HERO doesn't limit the number of PsychLims a PC can have, just the number from which he can gain build points at any one time. And that limitation on them is a
suggested rule- if a GM wants to let his players play utter basket cases, he's free to do so. There is no hard and fast limit- whatever limit on build points from a given disad is defined by the GM (HERO 5th, Rev., p 326). He can even vary that number between disad
types.
Hero's psychological limitations have always bothered me. Superman's vow not to kill is apparently moderate, since he has on numerous occasions made exceptions.
AFAIK, he has only intentionally killed 4-5 people in the history of the comic books- Doomsday (possibly more than once) and the 3 worst inmates of the Phantom Zone- General Zod, Faora and Quex-Ul (albeit versions from the Time Trapper's pocket universe). And he only did that after they escaped after that universe's Superboy died, and they were able to kill everyone on (that) Earth. He killed them by first exposing them to (that universe's) Gold Kryptonite, then to (that universe's) Green Kryptonite.
His battles with Doomsday are arguably all self-defense.
The only other occurrence may have happened early in the Golden Era when dealing with a thug with a gun.
Others have died because he couldn't save them.
So I'd put Comic Book Kal-El's PsychLim against killing pretty high.
As for other media, I understand he took an action in
Superman Returns that resulted in the deaths of 3 of Lex Luthor's henchmen, but since I didn't see the film, I can't say if that was the desired result or an unavoidable side effect.
So again, a pretty high code against killing.
