I didn't even know this figure existed before finding him today - the DC Super Friends Hero World Robin by Fisher-Price:
I still don't even have a Hero World Batman, for heaven's sake! But I do now have Dex-Starr, The Joker, The Bat-Copter, and now Robin. So it's now officially a 'collection' whether I like it or not.
The massive accessory will just sit in a drawer here, but it does shoot a couple discs (and shoots them well) in addition to clipping to Robin's back into a couple relatively unobtrusive holes WITHOUT making him topple over! I don't like the accessory, but I applaud the engineering of the whole package.
I love this Robin, and am glad to not have known about him before finding him because I might have gone crazy looking for him! And at only $8 at Big Lots grabbing him was a no-brainer.
Now, go crazy looking for him yourself!
