Simple premise; list two(or more) characters and a competition for them to compete in. It can range from something simple like two characters fighting in an open field with their standard gear, to unique scenarios like who would win in a race if both given the same car. The next person says who they think wins, and posts their own competition afterwards. I'll start;
Callis vs Yuu, fighting in the DK arena
Round 1: Callis has his old swords, no fire powers for Yuu Round 2: No restrictions, Callis has his current swords
Round 1: Callis. Yuu is much weaker without her flames, and Callis has endlessly more experience and training.
Round 2: Much harder to decide. Assuming they're not as conflicted about the conflict as in Hands, Yuu will try to use her tears to stick Callis to the floor, negating his advantage. I give it to her 6/10 for this.
Dan versus Haruko, dojo. Out of character. KO or incapacitate to win.
Given the environment and Dan's durability, I'd say he destroys Haruko in round 1. A few decent punches from him and Haruko's down for the count in base form.
Round 2 is a bit trickier. Haruko isn't much more durable, but she is much faster and able to attack from a distance. I think she could take the match over half the time if she managed to skate around Dan and pepper him with ranged attacks until he ran out of energy.
Jose vs Cadence, fighting in a large open grassy field. Fight until KO or death.
Round 1: In-character, normal Cadence and Jose Round 2: Normal Jose vs sober Cadence(much more irritable than normal Cadence, forgos calculated strategy for outright berserker rage)
I will go with Cadence in Round 1 since she will be smart enough to avoid getting trapped by Jose, or place in a losing situation. However, I do think it would be an entertaining exchange, especially due to their powers.
For Round 2, It might go either way depending on how well Cadence's berserk fueled attacks can end Jose, before he could come up with a plan to trap her.
If Cadence has her medal, then this won't be much of a fight
ALL THE Hate DOLLS (Haven, Jane, Ash, Cadence w medal, and Martha,) + Yuu and Marika vs MIYATA FAMILY (Aria - no wolf familiar or satellite, Alex, Elyssa, Erin, and Haruko)
Setting: Big Strong Hands - Just Replace the ones protecting the Orge body with the MIyata family
ROUND 1 - In Character with the goal of the Miyata Family trying to capture the dolls alive, where the dolls are trying to steal the body
Round 1: Dolls win. Cadence is a good counter for Alex and Aria, with her plant manipulation and Industrial Poison to counter Aria's plants. Plus...it's near impossible to capture Cadence alive given her plant body.
Round 2: Again, dolls for the reasons outlined above. The only people who actually matter are Yuu, Haven, Ash, Martha and Cadence vs Aria, Alex and Haruko. They'd simply be overwhelmed.
Team machine vs team cannibal! Falken and Eve vs Masako and Huntsman!
Setting: Island from Send The Child to Arata
Win condition: KO/death/trapped in a glass container with no hope of escape.
Could go either way, tbh. Seems to be just a matter of who loses their 'super form' first. I kinda see this just ending in a double KO most of the time, with Chase having a slight edge.
Amelia and Alexis run the Osaka Ablaze gauntlet! Both are healed after every round, regardless of the result. This takes place after AvA, so both are willing to work together. Both have full access to their abilities and summons.
Setting: Osaka, in the corresponding fight locations
Win condition: KO or death
Round 1: Taka and Washi Round 2: Baku, Mu and Uta Round 3: Masako and Andy Round 4: FMY 1
Round 1: Easy win for Amelia and Alexis. Magnetism won't stop fire and darkness from coming through. 9/10 their favor.
Round 2: Baku would go out to a fireball to the chest pretty quick, and that's going to be bad for him. Mu and Uta will be stronger, but still, I see them being taken down. 8/10 their favor.
Round 3: No. Andy is a total non factor. His bullets get melted before he's flash fried. But Masako is a lot harder to put down, possibly impossible for those two. It would go especially bad when he gets his teeth in and copies their magic. 8/10 Masako and Andy.
Round 2: I think this comes down to surviving long enough to land a good hit, which Amelia and Alexis can do easy. I give them 7/10 at least.
Victor vs. Arlana, forest. KO. No fusion with Sun for Arlana.
Gotta give it to Victor. Arlana is great if you give her enough time to summon the cards, but Victor can easily get closer to her if he uses his armor. Arlana could answer with any of her cards (if she survived the first strike) but i don't think her regular cards would be useful against the Tiger Armor.
She barely knows how to use her own tarot armors (the Princess, Prince, Queen and King), too. The male ones that fuse with her would protect her, yes, but she isn't great at close combat and the female ones that fight on their own are terribly limited, they are like a really basic AI.
Now this one is interesting; raw strength vs versatility. Ariana seems to have more durability than Loveline, so to me it looks like a matter of if Loveline can survive long enough to wear down that durability.
Round 1: Tough to say, but I'd have to give it to Ariana 6/10 times. The open ocean is one of the best environments for her control over water, and should Loveline be knocked into it, Ariana could either drown her or trap her in ice to win the match right there.
Round 2: Now, I'd give it to Loveline 6/10 times. Taking away most of the water puts Ariana closer to Loveline's power, and lets Loveline have to worry less about projectiles coming from the ocean.
Marceline vs Ash vs Dan vs Jose vs Gem Ariana...in a baseball batting match! They are each given an indestructible bat and baseball, and have to hit a ball as far as they can. Who can hit the ball the furthest?
Alternative round: Instead of the ball being lightly tossed, it is thrown at them at top speed by pre-Cave Gen and given 3 strikes. If they can't hit it, they get a score of 0.
Normally I would give this to Jose. Dan can probably swing harder by sheer bodily strength, but Jose can twist the ground beneath him to increase the force he unleashes immensely. However, if allowed, Marceline can injure herself to a horrible degree and hit even harder with the boost she gets when in pain.
Alternative round I say Dan. He's had a lot more time to develop precision and Jose's earth bending technique wouldn't be very accurate. An injured Marceline also couldn't swing as well.
Shi no Kaze and Katsuo vs. Sid Renen and Rin Shishioh, dense woods. KO or death for Katsuo, Sid, and Rin, Shi considered incapacitated if placed in her sheath.
Round one, Eve stomps. Haruko is just too fragile. One hit from Eve will wipe her flat out of existence. Eve 8/10. Haruko wins when she holds out long enough to wear Eve down with explosives.
Round two is more complex. Haruko is much more effective in this form. She can nerf Eve considerably and practically dance around her. If she can still use her explosive knives, Eve will be reduced to a red hot endoskeleton eventually. 7/10 Haruko, Eve wins when she gets a lucky cannon shot in.
Dan wins, like a boss. Toramaru is peak human/x2 human with mild pyrokinesis. Dan has the experience, stats and skills edge.
Chase goes through the "A Night at the Castle" Gauntlet.
1. The Clown (Decoy bodies that entangle enemies with ribbons upon being destroyed) and Snake (High agility, speed and poisoned spear) Vampires 2. The Werewolf (Werewolf and can create Shadow Wolves) and the Succubus (Blood Weapons and Pheromones) 3. The Armored Vampire (Enhanced strength and durability, unless he isn't touching the ground he can redirect all damage to the ground) 4. The Wizard Vampire (Gravity Magic) 5. The Darkness Vampire (Total Darkness, Sensorial Diminishment to enemy and Conceptual Black Flames)
1. Chase wins pretty easily I feel. Fire can destroy all those clones quickly. 2. Chase is immune to the pheromones, so I would give this to him as well with more difficulty. 3. This one is tough, as Armura took on so many characters at once. I would give it to Chase 7/10 times, though. 4. See...this one is difficult, as we were never shown his durability. But he did seem to easily redirect Crow's rail gun attack. I can see the wizard winning 6/10 times. 5. This one could go either way. Chase can't sense Cavaler due to him having no soul, and Cavaler took on nearly the entire group on his own. I can see this being a 50/50 split, it mostly coming down if Chase can figure out where Cavaler is in time.
Yamiko vs Osaka Heros! Her powers; create many objects(mostly knives) out of magic energy, super speed, able to create fog that impairs vision and allows her to teleport inside of the fog.
Round 1: Rin and Yuriko Round 2: Sid(no Gainen powers) and Raisa Round 3: Crow and Toramaru Round 4: Dan Bonus round: Gem Haruko
Location: Osaka streets Win condition: Death or KO
Round 1: Yamiko crushes. Rin is practically a nonentity due to her inexperience in Hidden World fighting at the date of Osaka. Yuriko is tougher, but lacks stats and experience as well. Haruko's been at this longer and she'll gut them like fish.
Round 2: This is a little more interesting and dangerous for Yamiko. Raisa is also inexperienced but may be a real force to contend with if she goes all out. However, the real danger is the horror of her taking Sid's sword. That thing in capable hands would have Yamiko as a puddle in five seconds. So I may have to give this to Raisa and Sid, mostly for Raisa.
Round 3: This is also rather dangerous for her. Toramaru is overall low stats but very durable, possibly enough to put a damper on her knives, and Crow's speed could lessen the effects of her teleportation. She would have difficult taking them down while spending her mana quicker than they spend stamina, and may lose via something as simple as a time out, although it's more likely she takes one too many shocks from Crow. However, if she does manage to take Crow out, Toramaru has a much harder time alone and with her focus all on him she should be able to take him down.
Round 4: One big factor in her favor here is she's dealing with only one enemy. She doesn't have to worry about potshots while fighting him. With that in mind, I give her the advantage. He can take a real beating, but she can give a greater one. With her speed she can easily keep out of range of his projectiles while peppering him with her own. He would have to close the distance to pose a real threat, and he would have a hard time doing that if she didn't get cocky. Dan is a smart fighter and may play at being more vulnerable than he really is to land a serious hit when she comes close to play with him, and may even use his attraction pheromones to bait that sort of behavior (Yamiko often expresses attraction as an increased desire to harm).
Bonus Round: Not hard for Yamiko. She effectively has the same powers with more strength and a much more aggressive attitude. Her teleport is especially useful. Hard for Haruko to pin her down with a spotlight when she's teleporting away. Haruko's going to be in pieces.
Arthur vs. Crow in a race! No time powers, straight road, 100 meters.
Gotta go with Crow. Arthur can reach mach 6 if he uses his wings at full power and without his chronomancy he can't get much further than that. Crow, on the other hand, can use his overcharge and, although the specifics of his skills aren't written down, i'd say he can get as fast as lightning.
Aria and Candence vs Jose and Goemon: No power limits, KO, forest at midnight.
Unfortunately for Jose and Goemon, they would have a very hard time putting down those two. They regenerate too quickly. Aria is also incredibly fast, likely too much for either of her opponents to land serious hits. I see Jose going down first to open up the ground for plants, then Goemon not long after.
Yuu, Marceline, and Cosmina vs. Martha, Haven, and Ash. Marika's kaspa basement, KO or kill.
