Wolf (SSBU)/Down smash
Wolf performs a kneeling one handed slash on both sides of him. It has great range, and the sweetspots of the move are located on Wolf's claws and are extremely powerful, with its front hitbox being among the strongest down smashes in the game, while its sourspots can still function as finishers despite being much less powerful than the sweetspots. This is one of Wolf's most reliable finishers and edgeguarding options, and one of his best moves in general as it can easily KO opponents with its high power and consistent ability to 2 frame punish characters. It has moderate startup as its first hit comes out on frame 14, but has low ending lag as it is interruptible on frame 44. Because of this, it is safe on shield if the move is properly spaced or if the second hit is the one that connects with shield. Lastly, it is also a great finisher when reading an opponent's tech options, mainly out of his neutral aerial or forward throw.
One downside of the move is that its sourspots outpriortize the sweetspots. Although its sourspots are still strong enough to be finishers, landing them regularly can lead to very inconsistent KOs. Therefore, it is important to space and position the move well so that its sourspots don't hit the opponent.
Overall, Wolf's down smash is one of the best of its kind in the game due to its very high power, good range, low ending lag, safety on shield if spaced, and 2 frame punish ability. Although it was slightly weakened in updates 3.0.0 and 3.1.0, these changes have not hindered it very much at all, and it remains as an invaluable move in Wolf's toolkit.
