Batman line: Mr. Freeze

Hand attatchments: Hand taken from figure itself.
Gatling gun: Soldier Force
Flame Thrower: Piece of rocket "fire" from original figure.
Jet pack is made from parts that came with the figure. I glued them together, added the center piece between them and presto, a jet pack.
Attatchments are interchangable.

Jet B.A.T.S. are yet another version of the original B.A.T.. Jet packs are used to attack from the air with several different hand attatchments.
