The Heroes escaped the Null Space and fight against Eggman and The Metal Legion. Sonic and his team battled the Metal Legion while the Justice League faced Eggman. The biggest surprise was because of the technologies from Luthor, Eggman was able to go toe-to-toe with the League! He even managed to land a hit at Superman of all people! Even Wonder Woman was having trouble. Sonic and the others were having trouble against their opponents as they were matched up against enemies of the perspective League member, i.e. Wonder Woman and Cheetah. Well, except Knuckles, who easily subdue Metal Dark Manta Ray, so they managed to switch opponents.

 

We then have a panel with Shadow looking badass after Metal Knightfall's defeat.

 

The League managed to figure out how to defeat Eggman but he then escaped to the Doom Egg until subdued by Clark and Diana.

 

Rouge found information that the L.E.X.X.E.G.G. gates are secretly drawing dimensional energy from one reality into another, if unbalanced, both worlds would be in serious danger as it can cause global destruction on both worlds.

 

Luthor used that intel to destroy Sonic's world and conquer the DC's world but then "Team 2" appeared to stop the Legion. Team 2 consisted of Supergirl, Krypto, Aquaman, Starfire, Cream and Cheese, Blaze and Big.

• This benefitted more for Hinata's growth overall and her fans should have support this for her instead of pairing her up with Naruto. Her resolve of destroying the Tenseigan, rescuing her sister and trying to stop Toneri after realizing Hamura's true words is a blessing for her character. And at the end when she told everyone that she's staying on the moon with Toneri and receiving closure after realizing what Naruto truly meant about her being strong... that's what was suppose to happen. But hey, everyone on that fandom was wearing shipping goggles. 
• Sasuke did have a role: helping Hinata destroying the Tenseigan as it was draining her chakra. Though, I wish he could've done more.
• The final battle... I wish it was better choregraph but due to limitations. Certain scenes weren't edited properly, i.e. Naruto was in his official The Last animation at one point and his Kurama cloak wasn't render properly. The addition of Sakura joining to assist Naruto... as much I like the idea, I really don't  . It would've been better to have Sasuke involve to have a proper Team 7 Vs. Toneri fight. Now that would've been more exciting. Though, overall, the whole fight doesn't make sense scientifically because you'd be questioning yourself, "how the f-ing hell they breathing on the moon, with no oxygen?!!"    Also, needs to be a bit longer, like an extra minute or 2. Although Toneri's final move led me to...
• The red string of fate! Properly for us, mind you (    ). With Naruto and Sakura's merged chakra healing the moon was clever and made sense. I didn't quite get it at first but then Sakura mentioned it when she woke up that her chakra merged with Naruto's with the constant healing over the years.
• And let's talk about the crucial part: NaruSaku! (I don't know if I missed it, but did it showed Sakura passed out after Hinata decided to stay with Toneri?) Again the limitations of using the same scenes from the cave because of her waking up in the hospital bed (wrong hospital bed too for that matter, it made it like she was critically hurt during the battle when we all saw that she wasn't, mind you) with Naruto at her side needs redrawing badly. That scene was awkward as hell. But Kushina's hair clip... THAT works very well. Plus, parallels! MinaKushi, Kushina's own insecurity with her long red hair = Sakura's own insecurity with her large forehead (which many fans seem to forgot that she was bullied about that!) Bringing back the bench scene and Sakura realized it was Naruto all along when he stated he wanted to kiss her forehead. And ending with them kissing!      Chef's kiss! A perfect way to end the movie...
