Bucky was apparently killed during the Fear Itself event— Bucky really going underground after his past as the Winter Soldier was exposed— that also resulted in the shield being broken and reassembled by Asgardian blacksmiths, who add some of the mystical metal Uru to the reconstructed shield, making it even stronger than before, although it is left with a noticeable scar that Rogers decided to keep to give the shield character. This premise was not observed in subsequent storylines, or considered canon, as artists have not continued depicting the shield with the scar. JLA/Avengers In the 2003-2004 Marvel Comics/DC Comics inter-company crossover limited series JLA/Avengers, Superman is given the shield by Captain America to wield in battle in the final confrontation with Krona, and is impressed with its might. When he asks where he could get one just like it while battling foes, Thor replies, "Enjoy it while thou canst, Superman. There is none other like it in all the worlds". Throughout the final battle, the shield changes forms between the pointed shield and the circular shield due to various temporal ripples caused by Krona's equipment, and Superman even loses the shield altogether at one point when he morphs into his energy form while Cap reacquires the photonic shield, although the metal shield reappears on Superman's arm after he morphs back into his regular form. Destruction of the shield Over time the shield has been damaged or destroyed several times within the confines of the Earth-616 continuity: In Captain America #302, the supervillain assassin, Machete, managed to destroy the one section of the shield vulnerable to conventional weapons while Captain America wields it: its holding straps, which made the shield much more cumbersome to use as it had to be held by its rim until Rogers could escape and replace the straps. In The Avengers #215–216, the Molecule Man used his total control over matter to disintegrate the shield, along with Thor's hammer, Iron Man's armor, and the Silver Surfer's board. After he does so, he comments that the board's molecules are "weird", and while there are "odd forces interweaving" among the hammer's molecules, the shield is "weirdest of all". He later reassembles these items, with the exception of the armor, as the electronic circuits are too complicated for him to understand at that time. During the 1984-1985 Secret Wars limited series, the shield is partially destroyed by Doctor Doom,
