The Symbiote Spider-Man from IC has 18 Defend on his first click and I wanna use that after the CoG events. Have him surrounded by other characters and have there defense 18. The questions I want answered are the following: 1) Are the characters adjacent to Spider-Man getting the 18 defense still have there own defense abilities like Super Senses and Impervious. 2) If a character getting the 18 defense from Spider-Man is standing on hindering terrain would he/she get 19 defense?

Thanks.

Yes to both.

:edit: okay, I suppose I should explain...
1. Defend only has you replace (that term is key in part 2) the Defense Value (number), not the entire defense, powers and all.

2. There is a mantra that can help you with that: "Replace and then modify". First, you replace your value with Spidey's higher value (note, replace) and then you modify it by one for occupying hindering terrain.

1) Yes. Powers like Combat Reflexes and Energy Shield/Deflection even add to the shared defense.
2) Yes, against a ranged attack at least.

The general mantra is "replace then modify." Since the attack would be what "triggers" Defend, and also what triggers any of the three above-mentioned modifiers, you'd apply the replacement effect and then the modifier.

Yes, on both accounts. Defend just replaces the defense of figures around Spiderman, say you have a figure with 16 Willpower, then the characters defense becomes 18 Willpower, when he is next to Spiderman.

You guys have been a great help with my question and quick with a response, thank you very much.

It is important to note that the general mantra is only applicable when a replacement and a modifer occur simultaneously. If I Perplex up my Joker's attack value, that happens before he would replace his attack value from Ra's. IF he does replace, the effect of the Perplex is ignored.

And of course, it's important to note that you should NOT push someone with Defend at all... unless their next click has the same or better DV with Defend

Also, IC's Unique Spiderman is a VERY high point cost to only use him for his Defend.... R Invisible Girl (CT) is a LOT cheaper and easier to use (I think she's under 40 points).

Yup, 37 points for 18 defend and stealth on the first click. Thanks for showing that to me, I wouldn't have known unless you told me. I just bought R Invisible Girl off eBay.

Thanks.

That is, unless it's the Man of Steel Supes and you need/are willing to push off of HSS with Defend to get the 18 DV with Impervious, better AV, and Charge. Pluses and minuses to both strategies here.
