This has been in my box of odds and ends for ages and I cannot for the life of me figure out what toy line it's from, except to say it's definitely not vintage Star Wars!! Seems a little big for a 3 3/4" figure unless it's a deluxe backpack of some description...it does have two moulded pegs on which to clip an extra part? Hoping the 'Caution' sticker on the side may hold an answer, pretty sure it's not from a line I've ever collected. If it's of interest to someone, please let me know and thanks for looking!
Thanks all! Stubbs/Savory100, I think you're onto something with the Zoids thing. I've never looked at this line before, they're pretty cool! All the hero figures seem to have blue plastic bits! I shall look through some pics and try to find the part!
