I'll defend myself.
I believe I outscale here, in terms of AP, skill, and lifting strength, hell I probably even out scale in intelligence. I'd say my best feat of breaking an arm, outscales slowly chewing through a skull as that's literally just LS of the mouth.
I carry a pen and have used it in fight's before. But that's about it so, I think I'm stomped in that category.
Eh, I'd say I LS stomp I'm able to beat my friend whom weighs 140 kg in wrestling via skill and strength stomp.
He wouldn't be able to bite my skull.
Let's say I don't have prior knowledge,
By the looks of him I'd just use boxing and kickboxing, because to be frank, I'm a social influencing victim. I'd keep my distance with him and try my best to fight against him while keeping a distance because I'm quite scared of monsters (holy shit this is so corny).
AP and strength wise, you're more well rounded while Salad Fingers mostly has biting as the main source of AP and strength in this matchup. (Also you should add the pen in standard equipment then in the profile.)
Speed wise, Salad Fingers has teleportation but other than that you should be faster in locomotion (unsure as to whether Salad can use teleportation to either stay out of range or escape submission holds).
Durability and stamina wise, given regeneration, Salad Fingers should be better in both terms of being able to take and recover from damage, and also should have more stamina/endurance than peeps like us beyond just higher in stats considering he tolerated/endured hostile environments (deserts specifically) with little to no negative/adverse effects.
Unsure if Salad Fingers can use teleportation on either the spoons or finger dolls to attack from further away (and the spoons are restricted in this matchup), but other than that both of you have approximately the same range in terms of melee unarmed combat and you should be better at utilising and controlling the range/distance in the fight.
Intelligence wise, you'd clearly be superior in most aspects, but unsure if Salad being able to talk to other stuff beyond humans would affect the fight, since SBA would mean that even if Salad tried, there would be no outside influence to help or harm either of you.
All that being said, there's potentially multiple copies of Salad Fingers that could appear in the fight due to the duplication so you'd have to contend with multiple opponents (though they may not effectively be controlled or organised compared to other characters with cloning/duplicating abilities so that may make it easier, though then again if they realise that you are a threat to either the original and/or to all of them, they would probably be smart enough to gang up on you, so you'd have to contend with multiple Salad Fingers who, while having potentially lower general bodily lifting and striking strength and speed, can use teleportation and are more durable and can regenerate, which may make the fight harder for you.)
Honestly the only reason I voted Salad was despite being outclassed/outdone in multiple stats, the regeneration and stamina as well as the copies/duplicates would mean that while you could get injured and are incapable of healing mid-fight/during the fight, Salad Fingers can heal, and has healed, from injuries that woud typically be fatal and/or extremely debilitating to regular humans, albeit slowly, which may mean that even if you inflict grievous injuries, Salad Fingers could recover from them and continue fighting, and that, in addition to having to deal with multiple copies/duplicates, would slow you down and wear you out eventually and give them time to swarm you and then from there be capable of utilising their biting.
And the teleportation would give them effective defensive and offensive tactics and strategies and techniques (such as evasion, escape from grappling, surprise attacks/ambushes, etc) which, again, combined with the copies/duplicates, would make it harder to fight them in melee unarmed combat alone.
The best shot/means/method you'd have to win (assuming in the worst case scenario that Salad Fingers has more potent regeneration than displayed so far) is to absolutely destroy/annihilate/eradicate/eliminate/decimate/erase/(insert other synonyms to do with removal of) every trace and every form of Salad Finger's existence (either completely or at least as much as possible to prevent yourself from being affected by Salad Fingers for as long as SBA requires for a victory/win), which would be nearly impossible to do with merely purely melee unarmed abilities.
