I don't--I'm seen several people who are in favor of Shockproof, but I've yet to actually get a good explanation for this: why is Gyarados only interested in an immunity, but when it's a resistance, apparently Gyarados is no longer interested at all, but even though it's not good enough to make Gyarados interested, it apparently still works for Togekiss somehow?and yes Volt Absorb seems a bit too much as we dont want an IMMUNITY to electric rather a resistance because then even IF CAP11 is paired with gyarados it wont be as effective, gyarados prefers an electric immunity on its partner rather than a resistance, see our point? our goal is for togekiss NOT gyarados, and with shockproof we're basically supporting togekiss MORE than we are gyarados. Plus CAP11 seems too bulky for the whole Volt Absorb thing.... Do you really want something with just about Base 80 Defenses and 90 HP to get a 50%(or is it 25%? im not sure) HP recover just like *snap* that?
I'm sorry, but that makes no sense. The worries over Volt Absorb are due to how it makes CAP11 immune to Electric-attacks, which is very appealing to Gyarados, who is 4x weak to Electric, and thus puts CAP11 at risk of being a Gyarados partner.
But yet, when it turns from a resistance, Togekiss is still interested, but Gyarados isn't? Why is that? I mean, Volt Absorb is only a worry because it makes an appealing partner due to the Electric immunity. But isn't it the same with Shockproof? It may not be an immunity, but it doesn't need to be. After all, as you claim in your own post, Shockproof lets CAP11 take one of the most powerful Thunderbolts in OU, Zapdos's (out of common stuff, isn't like only Magnezone's better?), and be able to beat it up with Stone Edge. How is an ability that still lets CAP11 take one of the most powerful Electric attack in OU something that the 4x Electric-weak Gyarados suddenly wouldn't be interested in for a partner, under your logic?
After all, that's the point, isn't it? Volt Absorb is too much, because it lets CAP11 come in on any Electric-attack it wants, and beat up the user of it right after, which makes it way too appealing to Gyarados, to be used as a Togekiss partner. But yet, if Shockproof is still good enough to allow CAP11 to take the most powerful Tbolt in OU and beat up it's user, how is that any different? Volt Absorb may still be "better", but Shockproof is still doing everything that Gyarados could wish for and more apparently, as far as Electric-attacks are concerned, so that's not too relevant. I mean, if we were actually talking about abilities for Gyarados itself, then yeah, Gyarados would definitely be more interested in Volt Absorb than Shockproof. But since we're talking about abilities for CAP11, there doesn't seem to be too much of a difference between them, as far as Gyarados would be concerned as a partner.
Of course, as I've mentioned before (as others), all of this Gyarados-partner talk is pure silliness, really. And, if FlareBlitz is correct (don't have time to check; going off to get some dinner soon), it seems that your damage calcs may be wrong, which is just as bad for Togekiss as it is for Gyarados (after all, this thing is supposed to be a partner for Togekiss, and it won't really be doing a good job of that if it loses to Kiss's top counters), and even if he's not, I believe he does have a case that CAP11 may not end up with Stone Edge (not sure if it's required for Fighting-types and don't have time to check right now), and even if it is, it's still coming off CAP11's weaker offensive stat and Zapdos typically run a Physically-Defensive set, at least let time I checked, which isn't good, so it just doesn't seem that Shockproof is good enough to me.
