Horrible reletive to Ganon's? They're both on par with "trash", neither are very good. Though I'll take your word for Zelda's being worse.
Dude, she has NO reliable answers to hiding in shield.
Zelda's grab frames are 12 for standing, 11 for running, and 10 for pivot.
Honestly, Zelda's grab is pure and utter trash, Ganon is trash too, but she'd be thankful for even his grab game.
No, down-throw only puts a 'couple' of character in a bad position for a chance of a follow-up, otherwise down-throw is just too laggy.
"Good" is reletive. Remember who we're talking about.
You may be able spotdodge Zelda's grab on reaction, but Ganon could have the same kind of trouble, his grab range is so poor that it'll most likely MISS without reaction.
The average start-up speed for a grab to start is frame 6. Ganon grab starts at frame 7, has the lowest range out of all grab (as I've mentioned several times before), a few characters could even duck below it/have their animation avoid it.
Damage wise, Ganon grab is so-so, but having follow ups is alot better. A 13 damage F-throw, 10 damage B-throw, 7 damage U-Throw, and 7 damage D-throw.
Ganon has one of the worst grab-games.
Ganon's grab range is crap, so?
Honestly, being able to grab is better then not. Zelda's damage and follow-ups are mediocre at best, but as I posted before, her she grabs at 12 frames standing, 11 running, and 10 pivot. Just about any smasher should be able to spotdodge them from shield. It means she has no answer to shield-camping which destroys her approach game, turning her from a mid-tier contender to bottom tier trash.
Honestly, Ganon's grab-game is trash. I'm not saying it's better then you are. I'm just saying, in spite of how bad it is, every Ganon player should get down on their knees and thank God (or whatever deity or naturalistic construct or person you consider relevant) that Ganon doesn't have Zelda's grab game.
Honestly, it's just unmatched.
Also. ZSS with a whopping 16 frames for everything.
Some are worse, but they have zairs and reliable ways to force approaches which allows them to *gasp* reliably shieldgrab.
Yes, Ganon is not the worst at something, amazing right?
