In 2010, he was the Wolverine. In 2011, he was Darth Vader. In 2012, Halloween was cancelled, because of Hurricane Sandy, although I did set aside a day for him to dress up in a few costumes (see the pictures below). In 2014, he dressed as a cub scout (which he was). in 2015, he went trick or treating dressed as the Grim Reaper, and we went with a friend from his school.
This year, he was the Blue Team leader from Halo.

He dressed up as a cub scout for Halloween in 2014, and we went trick or treating together. Great memories!
