Many players are hard at work in the lab coming up with combos for a whole bunch of characters. Trag's released a ton of them, Isedelica came up with several, really creative Dante and team combos, and many other players are doing their part, too. Here's just a sampling of what you can find over on YouTube!
Isedelica's back with yet another absolutely bonkers Dante combo. It's not all that viable, but that doesn't take away from just how wild and flashy it is. Maybe it'll give you some ideas of what to incorporate into your Dante game.
fuerzadepegaso posted a pretty nasty fly, unfly, relaunch combo with Magneto. If Magneto's on your team, you might want to check this one out and add it to your arsenal.
XXTeefXX has a compilation of a bunch of different combo possibilities using his bread and butter flight combos. The X-Factor combo that starts at around 1:05 is particularly nasty, and would easily kill every character in the game. Check it out!
Tragic published a whole bunch of Super Skrull combo videos. One of the videos utilizes the air Down+H loop discovered by Isedelica, and the other is a nasty combo that Tragic came up with that does about 954,000 damage without X-Factor. You can find the rest of the Super Skrull vids over on his YouTube channel.
