Jacob The Slimeboy
Jacob T. Slimester, also known as Jacob the Slimeboy, is a high-energy kid with a body made of stretchy, malleable slime. Jacob is a slippery glass cannon grappler. He excels at aggressive, fast-paced pressure, using his elastic limbs to grab and strike from mid-distances. While he can dish out early KOs and keep opponents guessing with his mobility, his light weight and erratic movement make him a high-risk, high-reward pick- one wrong move and he’s easily punished. Still, that doesn’t stop the hyperactive green goober from being fun to play!
Neutral B: Playdate Swing
Jacob’s signature mid-range grab.
On Hit: Jacob grabs the opponent’s hands for a "playdate." He swings them around in a joyful circle until he gets too dizzy to hold on, accidentally launching them away with serious force. If you pull forward, Jacob will throw the enemy backwards and vice versa obviously. If you don’t pull anywhere, he will simply throw forward. You can start flying if you either hold up or B during the spin.
On Miss: Whiffing this move is dangerous! Jacob’s overextended slime arms snap back and wrap around his own body in a cartoonish tangle, leaving him wide open for a counter-attack.
Side B: Gut-Check Time!
Inspired by the legendary Daffy Duck, Jacob stops to wind up his rubbery legs before becoming a lime-green blur!
The Charge: Jacob charges in place, building up massive kinetic energy.
The Zoom: Upon release, he rockets forward at terrifying speeds, hitting anyone in his path. While it’s not his heaviest hitter, it is an incredible tool for recovery and mixups. You can even jump cancel after hitting.
Pro Tip: Be careful when charging this high in the air—the horizontal speed is no joke, and you might just zoom yourself right off the blast zone!
Down B (Air): Just Weightboy
Jacob shifts his slime density to the extreme, transforming into a massive, heavy weight!
The Drop: Just like Kirby’s Stone from Smash, Jacob plummeting down will crush anyone caught underneath. It also deals splash damage to those nearby when he hits the ground.
Safety First: While in weight form on the ground, Jacob is immune to attacks.
Mixup Potential: Don’t want to commit? You can cancel the transformation mid-air to bait out an opponent’s reaction!
Down B (Ground): Melon Seed Shooting
Inspired by the Yoshi series, Jacob eats a whole watermelon, and is able to spit rapid-fire seeds to harass opponents from a distance. Every 5th seed shot out becomes a "Super Seed", which does more knockback and damage.
Up B: Stretchy-uppercut
A classic multi-hit recovery and finisher. Jacob curls into a ball, spindashing into the air before delivering a massive, slime-fueled punch!
The initial rise hits multiple times, dragging opponents upward with Jacob as he ascends. At the peak, Jacob launches a giant uppercut.
The Catch: While it’s great for height and early pressure, the move doesn’t have much "oomph" for KOs early on. Keep your eyes on the opponent’s percentage—once they hit 90%, this move becomes a lethal finishing blow!
1. Slip and Slide Strongs
Jacob’s most unique trait is his lack of friction. Unlike other characters, Jacob doesn’t stop in his tracks when charging a Strong attack!
The Slide: Use your momentum to slide forward while charging Up, Down, or Side Strong.
Catch ‘Em Off Guard: This is perfect for closing the gap and hitting an opponent who thinks they’re safely out of reach.
2. The Down Strong Gamble
Down Strong is Jacob’s fastest and most powerful smash attack, covering a wide area around him. It’s his best tool for securing a KO, but it comes with a massive catch:
The Risk: If you miss (whiff), Jacob enters a hilariously long, vulnerable animation where he’s completely wide open.
The "Cool" Factor: If your opponent is on their last stock and struggling to recover at 100%, go for the Down Strong read. Just remember: if you whiff and get punished for it, that’s entirely on you, bro!
The Down Air (D-Air) Specialist
Jacob’s Down Air is one of his most versatile tools. It’s not just an attack; it’s a mobility option!
Combo Starter: D-Air is incredibly useful for starting combos at almost any percentage. Use it to pop opponents up and keep the rhythm going.
The Slime Slide: If you use D-Air while close to a wall, Jacob will briefly slide upwards along the surface.
Wall Jump Synergy: You can still wall jump immediately after the slide, giving Jacob some of the most unique recovery paths in the game.

A Note from the Creator, Kingston:
This is my very first Steam Workshop character! I’ve put a lot of heart into Jacob’s ADHD energy, his stretchy physics, and his overall cartoony animations. Your feedback is incredibly valuable to help me balance his "Glass Cannon" stats. Really…like I need him to be fair and fun at the same time.
