Sorry for the delay. For
Sidekick we'll take
Bucky Barnes
Captain America's loyal sidekick. I still remember when he died, nothing says sidekick like getting blow'd up.
In the closing days of World War II in 1945, Captain America and Bucky try to stop the villainous
Baron Zemo from destroying an experimental
drone plane. Zemo launches the plane with an armed explosive device on it, with Rogers and Barnes in hot pursuit. They reach the plane just before it takes off. Bucky unsuccessfully tries to defuse the bomb, and it explodes in mid-air. Bucky is believed killed in action, and Rogers is hurled into the freezing waters of the
North Atlantic.
