If you thought the Merc With a Mouth was finished taking swipes at Fox, Wolverine and the X-Men, think again.

Ryan Reynolds' Deadpool stealthily infiltrated a Japanese trailer for "X-Men: Apocalypse" to deliver "my two cents on five things you may have missed."

"I know what you're thinking: 'An after-credits scene for a trailer? I thought they only did that for movies,' right? Well, not everybody makes it to the end of Fox movies, so now we're doing it after trailers."

Although Fox Japan debuted the trailer online on Friday, it was clearly released sometime last month to promote the June 1 theatrical release of "Deadpool" in Japan. The film grossed $6.5 million in its first five days of release, a record for the X-Men franchise.

To date, "Deadpool" has earned $14.6 million in Japan, and $780.4 million worldwide. It ended its 18-week theatrical run in North America with $363 million.
