I know other people have asked this before and I know that Soaring Characters can only affect other soaring characters but what about graounded characters, can they shoot at them from Range or close at all?

A standard height grounded or elevated figure may make ranged attacks against soaring figures by halving its range value.

Close combat actions can be made with the Leap/Climb power.

Sorry, but I really am not sure what you are asking.

I am reading this one of two ways:

1) Can grounded characters shoot soaring characters?

2) Can soaring characters shoot grounded characters?

I am pretty sure you mean #1, since you start off saying that you know soaring characters can only effect other soaring characters... but all those 'they's and 'them's kind of make it confusing. Not to mention I have no idea what, "...or close at all?" is supposed to mean.

If you are indeed asking #1, yes. Pages 26 and 27 of the LoSH rule book:

Soaring characters can draw lines of fire only to soaring characters, giant characters, and colossal characters. A nonflying character or a hovering character can, however, make a ranged combat attack against a soaring character, as shown in Figure 13-B. Soaring characters can make ranged combat attacks against both adjacentand nonadjacent opposing soaring characters, giant characters, and colossal characters to which they have a clear line of fire, even when the soaring character is adjacent to opposing characters.
Unless the attacker is a giant character or a colossal character, halve the range of a nonflying character or a hovering character when drawing a line of fire to a soaring character. Lines of fire drawn to soaring characters from nonflying characters or hovering characters ignore hindering terrain and are blocked by giant characters, colossal characters, and elevated blocking terrain. A line of fire drawn between two soaring characters, a soaring character and a giant character, or a soaring character and a colossal character is not affected by terrain, hovering characters, or nonflying characters.

What if they have Hypersonic Speed and/or 0 range? Can they attack anybody who is soaring?

It would help if you specified who "they" are.

I'm guessing that "they" are the non-flying figures. (I'm also going out on a limb to assume that when he says "grounded" he means "non-flying" although what I'm going to say applies to non-soaring fliers, too.)

A standard height figure with 0 range and HSS at the grounded or elevated level cannot make an attack against a soaring figure. If you could somehow modify your range value, you could make a ranged attack, but that really isn't in line with the question.

Or if the character has Super Strength they could throw an object up at the soaring target.

Not with HSS.

HSS option 1 allows a close or ranged combat attack. Throwing an object is a ranged combat action. So you can throw an object with Running Shot, but not HSS.

They being Icons Flash and Johnny Quick against really any Superman and thanks that helps.

"Affect" was the right word choice in that case. "Effect" as a verb means "to produce as a result" or "to bring about."

Rule of thumb: affect is usually a verb while effect is usually a noun.

Not often I get to correct Normalview on something.
