Bucky is the moniker used by Captain America's sidekicks, in honor to the original one:
- Bucky Barnes, original bearer of the name.
- Jack Monroe, sidekick to the 50s Captain America. Monroe is currently known as Nomad.
- Rick Jones, who donned a Bucky costume while helping Cap.
- The Bold Urban Commandos or BUCkies, partners of Superpatriot (John Walker). When Walker reformed and temporarily became Captain America, Lemar Hoskins, one of the BUCkies, went with him as Bucky before changing his codename to Battlestar. The other BUCkies became Left Winger and Right Winger.
