That purple seaspray is just a faded blue one that's been out in the sun - you can't fool me, Junkie!
It is a small set. I love the G2s and nearly have 'em all. That purple Seaspray is not a variant in the line. It is faded or a mishap in production.
I'm not sure of it's orrigin, but I know it is considered a variant in the line. It's just not packaged any differently than the blue one.
I saw somebody selling it on ebay (I thought). And they said it wasn't a variant but an accident production error. I haven't seen a purple Seaspray listed in TF resources yet.
Here we are: Transformers Purple Seaspray Rare G2 G1 - eBay (item 280564594895 end time Feb-17-11 00:52:35 PST) And I don't think I'd pay $80 for him. But I guess it's for a unique G2 buyer.
From the description: "The blotch of blue us a factory mistake which makes this figure one of a kind." He is referring to the "blotches of blue" that are present under the figure as the "factory mistake". I think the purple Seaspray was actually part of a test run by Hasbro.
Maybe it is. I can see why it never went beyond a test. lol I plan to complete my G2 line, but I don't think I'll be adding him.... unless he became a red Seaspray.
