Marvel Comics (Marvel Comics Avengers Film Universe only) cooperated with Paramount before, and Paramount participated in the production, so it has its logo (the first picture, Mountain+Star), and the copyrights of X-Men, Knight of the Evil Spirit and Spider-Man (the copyright of Spider-Man has now returned) were sold to other companies, so their film titles will have the logo of Fox or Sony Colombia. After Marvel Comics was acquired by Disney, Disney was only responsible for the production, not the production, so there was no Disney logo, but at the end of the film, there would be a line saying "This film was produced by Disney Company with honor", about a few seconds before the egg painting at the end of the film (typing by mobile phone, so tired, I hope to adopt it ~).
