put sonic's dair semi spike back...
Its amazingly strong if you hit it with the sweetspot. even the likes of toon link and luigi cant do anything to get back on the stage if they are hit by that off the stage (which of course sonic can recover from every time thanks to the spring, so that shouldnt be taken into account)
Sonic's d-air is a stall-then-fall (diagonal fall) semi-spike at the beginning of the attack, 100% of the time against aerial opponents.List of Spikes in Brawl
If I missed anything or made any mistakes, please tell me. If you have a better or clearer description for a sweetspot, also tell me. This stuff is pretty obvious, but it's a nice resource.
In case you didn't know:
Spike - An attack that sends theopponent directly downwards until hitlag wears off. You cannot meteor cancel in Brawl, therefore all meteors are now spikes.
Stall-then-fall - An attack that sends the user directly downwards. Some stall-then-falls are spikes if they hit as the user begins their downward movement.
Semi-spike - An attack that sends the opponent horizontally, with significant downward momentum.
His F-air semi-spike is more elusive, but the situation that I came up with for that (whether you want to accept it or not) is:
- lower-front part of Sonic's hitbox (under the head, but front of his arms)
- specific DI needed, most likely downwards DI.
