The trailer then begins with Mario and Link fighting each other on Battlefield. The rock structure in the background is zoomed into to reveal behind it, who then goes to examine something rupturing the ground. A flower then emerges from that spot, much to Chibi-Robo's happiness. Returning to the foreground, Mario attempts to shoot a at Link, but it ends up hitting the flower instead.

The trailer starts with a recreation of the beginning of Mega Man's reveal trailer for, opening with a siren and a "New Challenger Approaching!" sign. It then cuts to a canyon at night, where Mario, Link, Kirby, and Donkey Kong glance up to the top of a cliff where the silhouette of a humanoid with spiky hair stands. A helmet forms around its head and its eyes light up, revealing the figure to be Mega Man. The song "Mega Man 2 Medley" from Super Smash Bros. for Nintendo 3DS and Wii U then plays as Mega Man leaps into the air and teleports out of the canyon, reappearing in an area similar to the stage intro screen from  and striking a pose. A splash screen with the tagline "Mega Man Rejoins The Battle!" appears before cutting to a gameplay montage that showcases Mega Man's attacks.

After the montage, Mega Man gets attacked and launched around Skull Fortress by Mario, Kirby, Link,, , , Pikachu, Donkey Kong, , , and , in that order.

's reveal trailer, titled "A Newcomer Smashes In!", was released in Dev Blog #5 for Beta on April 1, 2016. It opens with and a motionless Sandbag on Waiting Room before an Online match as the music track Waiting Room plays. A robotic voice on the floating monitors then tells Captain Falcon to train with the Sandbag while waiting before transferring him to the match. Suddenly, the stage's background changes and the robotic voice asks what is happening. As the music fades out, ＣＬＥＯＤＢＯＴ, a robotic entity bearing the likeness of Gregory McLeod, installs himself onto one of the monitors. He then says "I must become the bag" and possesses the Sandbag on the stage while laughing, leading it to leap forward as a splash screen with the tagline "Sandbag Smashes Back!" appears. A custom arrangement of the Waiting Room theme and various songs from the Super Smash Bros. series then plays over a gameplay montage of the playable Sandbag.

The SSF2 logo then appears, ending the trailer.

This trailer (and the dev blog itself) was created as an April Fools' Day joke, as the date it was released and the absurdity of Sandbag being playable lead many people to think that Sandbag would not actually be playable in SSF2. However, two days later in Dev Blog #5.1, Sandbag was revealed to actually be playable, with the joke instead being to trick people into thinking otherwise.

Mini-Trailers
The Super Smash Flash 2 Mini-Trailers, or SSF2 Mini-Trailers for short, are small compilations of videos showcased on McLeodGaming's YouTube channel, with each one featuring a single previously announced character. Because they are described as "concept trailers", these videos feature "prefabricated gameplay", showing dramatizations of the actual gameplay and how each character's moveset could work.

Below is a list of the four Mini-Trailers in chronological order of release.

Mega Man
Mega Man's Mini-Trailer was created by former developer RoyMaster4 and released on February 14, 2009.

Other trailers
Below is a list of trailers made for miscellaneous purposes, such as April Fools' Day jokes, in chronological order.

An Incredible Newcomer!
On April 1, 2014, McLeodGaming uploaded a trailer to their YouTube channel which supposedly revealed Mr. Incredible as a playable character in SSF2. The following day, the name and description of the video were edited to show that this was, in fact, an April Fools' Day joke and that Mr. Incredible would not actually be playable in the game.

It opens with the McLeodGaming logo as a custom arrangement of the song "The Glory Days" from  plays. Zero Suit Samus, Ness, Zelda, and Kirby are then shown running off the edges of Final Destination, where Mr. Incredible is then shown standing in the center. Several gameplay clips are then shown for him, but aside from basic movements like walking and jumping, he is only shown using one attack, which was used as his down attack in the original Super Smash Flash. The screen then remains black for 20 seconds with no music, and the trailer ends with Mega Man using his side taunt at Mr. Incredible at the last second.

Although very few animations for Mr. Incredible were shown in the trailer, former developer Jacob Tjolsen, who had programmed Mr. Incredible into the game, later revealed on January 2, 2022 that he "nearly fully designed" the character but held back on showing more of him as to not make the development team "look distracted".
