I don't know. The wrecked mask doesn't look that bad, I think a bondo repaired one would look worse. Unless you are good enough to make the replaced parts look really good.

It actually looks really cool as a display piece, but just looks stupid if you wear the thing. It also tilts heavily to one side if you try to wear it, because its weight is so out of balance. If it was complete it would be a super awesome really creepy looking mask.

Be curious to know if the ones at your Toys R Us are in as bad of shape as the ones at mine. Three good ones, six broken ones, and one missing from the box entirely is a pretty high failure rate.
