Base Deku:
If you use manchester after delaware air variant, it will still hit if you land on someone because as long as you're in the air, manchester will keep it's lingering hitbox, allowing you to do some funny combos.
Vigilante deku:
You look a lot cooler if you activate the ult after using delaware grab air variant.
Base Stain:
I dunno if it's patched yet, but not activating blood curdle after hitting someone with curdle pierce will not put the move on cooldown.
Mastery stain:
You can do headbutt right after 4 m1s because it's startup is really fast, similar to quintuple and reality barrage, so i call it the concussion combo.
Dabi:
You can actually shoot infernal burn into the air, if you're good enough, you might be able to do a trick shot by hitting them after an uppercut, oh and also, infernal burn has a lot of range, you can literally snipe someone from across the map.
Mastered dabi:
If you use glacial cinder on someone who is near a wall, they will get glitched into it and the anti stuck will activate, causing them to get fling onto the nearest spawn point to their location, using the 1st and 2nd charge of infernal assault, and also the 2nd use of phantom shot on someone near the walls will fling them away.
Todoroki:
Absolutely nothing, this character is not fun, it's too op, but he's not fun to play.
Bakugo:
Using blast catapult on someone near walls will throw them behind you instead, the knockback is still the same tho.
Shigaraki:
If someone is using a move that has hyper armor, and you hit them with void steps, they will still do the move and you'll get hit cuz you have no i-frames.
Ida:
You can land a free true aerial downslam after jet stream 2nd charge if you don't feint it into other moves, you can also stack chronos on the same player without letting him escape if you have teammates.
Warp portal:
This is more of a painful fact rather than a fun fact cuz warp punch actually gives the enemy i-frames so the only thing you can combo into that move is your really fast grabs that your enemies cannot cancel with m1s in time, but i am still leaving a fun fact, don't worry warp mains, so, we all know reality barrage has no i-frames after it, but it doesn't give it to the target either unlike portal combo, so if you have teammates, y'all can stack reality barrage on the same target by grabbing them with reality barrage immediately after they exit the portal.
