Fox (SSBM)/Down throw
Fox throws the opponent against the floor and shoots them with his Blaster. The throw portion of this move is a Meteor Smash, which can allow it to launch someone into the bottom blastzone if they are not prepared to Meteor Cancel or stage/wall tech it. In most positions, it can allow for a tech chase, although against most of the cast you cannot tech chase on reaction after, instead having to read their tech option. Against especially light characters like Jigglypuff and Mr. Game & Watch, you can reaction tech chase after as long as they don't DI the throw in an ambiguous way.
Down throw is usually used against characters whom Fox cannot up-throw up-air, such as Samus, as a way of potentially securing a strong hit, like a read with upsmash. Generally speaking, it has the least usefulness of Fox's throws, but may be a good option in certain matchups.
