Falco (SSBB)/Down throw
Falco throws his opponent to the ground, shooting them with his Blaster four times with each shot dealing 2% each. Falco then throws his opponent which deals 1% for a total of 9%. Unlike his back throw and up throw, the laser shots are guaranteed to hit unless Falco is interrupted during the throw animation as unlike those throws, Falco shoots his lasers before he throws his opponent.
The throw does very weak horizontal knockback, sending opponents at a 50° angle and not sending them into tumble until around 30%-50% (depending on the opponent's weight and how stale the throw is). The throw also has very low ending lag, only having 11 frames of cooldown. These factors make the throw an excellent combo tool. At low percents, the move can be used to chaingrab opponents. The effectiveness of the chain grab depends on the falling speed/gravity of Falco's opponent (as well as if his opponent has any strong options to escape the chain grab) although even if the opponent cannot be chaingrabbed, Falco can still followup into a dash attack, an up smash, a neutral aerial or a down aerial, with his most damaging followup being his gatling combo (dash attack into up smash). Against flaotier characters, Falco can usually build up around 30%-40% although on fast fallers and hevayyweights, he can build up to 65% damage with a 0% chaingrab into a gatling combo.
If the opponent is near the edge at lower percents, Falco has two options. He can either perform a boost pivot grab to turn around and continue the chaingrab or, he can perform a down aerial and meteor smash the opponent offstage (though the opponent can SDI back onto the stage). While the down throw down aerial isn't too reliable due to meteor cancelling (especially at lower percentages), along with the opponent's ability to SDI back onto the stage, it is very effective on Wolf in particular, due to his 60 frame meteor cancel delay along with his poor vertical recovery, allowing an easy edgehog. A very situational technique is the DFS (Drill Footstool Spike) - in which Falco performs a down aerial followup to the throw offstage and it is meteor cancelled, he can use a footstool jump off of the opponent. However, the opponent can usually edge sweetspot while jumping, unless they meteor cancel too late or delay their jump. Down aerial can also be used onstage to lead into a followup at lower percents or to start a tech-chase at higher percents.
Even when the throw puts opponents into tumble, the throw is still highly useful due to its low ending lag along with Falco's tool kit. Depending on the opponent's DI, Falco can land the first hit of his neutral attack which is unavoidable. Below 60%, the jab will cancel the opponent's tumble state, which can then lead into Falco's jab cancel setups. Above 60%, the jab will no longer cancel the opponent's tumble state and if they DI down, there is a chance to knock the opponent onto the ground, opening a laser lock opportunity. However, this is too situational and difficult to perform to be effective. Falco can also go for another grab as a mixup when the opponent is in tumble, resetting the situation if he lands the grab. At higher percents, Falco can finish off his opponent with a DACUS which when performed perfectly, requires a buffered air dodge in order to avoid, making it a solid setup. These setups can be avoided however by DIing up although if Falco reads this DI, he can predict his opponents landing and potential punish it with either another grab, one of his aerials or even a smash smash.
The only downside Falco's down throw has compared to a few other down throws is that it is not capable of reliably 0-deathing any characters as it sends opponents into tumble once they reach around 50%, while still being completely ineffective as a KO move (although as mentioned before, a down throw into BDACUS is an effective followup at high percents depending on the opponent's DI).
Overall, Falco's down throw is easily his best throw as well as one of the best throws in the game due to its high damage racking potential, low knockback, low ending lag (leading to its excellent chain grabbing potential) and high versatility, as well as working very well with Falco's moveset.
Chain grab list
This is a list of how many chaingrabs Falco can get on the whole cast, made by DEHF. This list goes by least chained character to greatest. There are certain escape techniques such as Marth's Dolphin Slash which can be used to avoid the chaingrab. However, if one can correctly buffer all of Falco's grabs, this issue is, for the most part, negligible.
