二 |     A wave of excitement swept through Marvel fandom after a low-quality leaked teaser for Avengers: Doomsday briefly surfaced online. This teaser appears to confirm the return of Chris Evans as Steve Rogers. Though the clip was swiftly taken down, Marvel Studios has not issued any official confirmation.      The viral teaser opens on a deeply familiar and emotional note. Steve Rogers is shown arriving at the quiet home last seen at the end of Avengers: Endgame. He parks his motorcycle, removes his helmet, and walks toward the house in silence. In the next moment, Steve is seen holding his Captain America suit, staring at it thoughtfully. This visual strongly suggests an internal conflict between his peaceful retirement and the call of duty.      The teaser ends with a tender image of Steve cradling his baby, smiling in contentment, before cutting to black with a slate saying, “Steve Rogers will return in Avengers: Doomsday.”          STEVE ROGERS in 4K for DOOMSDAY#AvengersDoomsday pic.twitter.com/odHqbH7suf     — a (@iahaanx) December 15, 2025                    This is followed by a clock-style countdown leading to the film’s release date. The teaser is believed to be one of four short previews planned exclusively for theatrical screenings of Disney’s Avatar: Fire and Ash, starting December 19.     Avengers: Doomsday is currently slated for a December 18, 2026 release. This follows a reshuffle of Marvel’s release calendar. The film will reportedly unite characters from the Avengers, X-Men, Fantastic Four and Thunderbolts. This sets the stage for a mega crossover affair. The sequel, Avengers: Secret Wars, has already been announced. It is set to arrive in December 2027.          New details on the ‘AVENGERS: DOOMSDAY’ trailers:• 1st trailer is focused on Steve Rogers• 2nd trailer is focused on Thor• 3rd trailer is focused on Doctor Doom• 4th trailer is focused on the entire movie#AvengersDoomsday pic.twitter.com/0YJOO9NNQO     — Prabhas (@Prabhas512678) December 15, 2025                    The Russo brothers, Joe and Anthony, return to direct after helming some of Marvel’s biggest hits, including Infinity War and Endgame. A beloved face of the MCU, Robert Downey Jr. is set to re-enter the universe. He will be taking on a new role. Formerly Iron Man, the actor will now be seen as Victor Von Doom, aka Doctor Doom.     While Evans had repeatedly denied involvement in the project, the denial just echoes the now-familiar Marvel tradition of secrecy.Also Read: Chris Evans and Alba Baptista blessed with a baby girl?。其实一个shell脚本加一个定时任务就能解决。    下面这个脚本同时备份MySQL数据库和网站源码，按日期命名，保留最近7天。Linux服务器直接放到/root/backup.sh，Windows可以改成PowerShell版本，或者把Linux脚本放在宝塔面板的Shell终端里执行。
