I don't know/particularly care for most of the official English names for things, because I've never actually seen it. And, well, since this was specifically mentioned as open... it seems prudent to fill this slot.

[b]Name:[/b] Minamoto Kotohime

[hider=Appearance]Please ignore the outfit. They're dressed properly, as it would set a terrible example otherwise.

[b]Age:[/b] Unknown

[b]Gender:[/b] Female

[b]Class:[/b] Shinigami, Captain-Commander of the Gotei 13 and Captain of the 1st Division

[hider=Powers]
[b]Overwhelming Reiatsu:[/b] Rather appropriately for the commander-in-chief of the shinigami, Kotohime's reiatsu is [i]enormous[/i], the pressure more than capable of trivially paralysing the weak, and surprising even the more prepared with the sheer amount--whilst it's possible to [i]expect[/i] a lot due to the position, nothing can truly prepare you for the sensation.
If it comes down to a battle of sheer power, Kotohime is more or less guaranteed to win unless her opponent can temporarily increase their strength to surpass hers. Yet, despite the enormous power, she has the utmost control over it, and can entirely hide her presence if needed... which is rather useful most of the time.

[b]Shinigami Arts:[/b] As a requirement for setting a good example, Kotohime has made sure that her skills--in all departments--are at the least 'respectable'. However, this does not make her anything remarkable where either wielding a [i]sword[/i] or kido are concerned. Shunpo and punching things? Now [i]those[/i] are her specialities.
She can do more with speed and her bare fists than most shinigami with fancy shikai abilities.

[b]Shunko:[/b] Combining kido with punching: a good pastime for someone whose shikai is about punching, and who prefers to punch than wield a sword. It serves as her main way of dealing damage directly in a fight--whilst her shikai and bankai have an air of inevitability about them, more worthwhile opponents are easier to take down simply by punching them the right way.

[b]Shikai:[/b] [i]"Feast Upon the World: BOBSWORD"[/i]. BOBSWORD goes from your standard, utterly-unremarkable zanpakutou to a less standard, but still utterly unremarkable set of knuckledusters, though the activation is incredibly obvious due to the upsurge in reiatsu. Their most basic effect is that, with every hit, a spike of Kotohime's reiatsu is left behind, acting as a conduit between the enemy and herself... and constantly draining their power, refreshing the captain-commander.
[i]Corruption:[/i] The flow of reiatsu from victim to Kotohime can be reversed--forcefully taking control of the affected body part through overpowering force and, once that is subdued, spreading further. With multiple hits, this still results in a net increase, whilst eventually turning the victim into a puppet, the full set of their abilities available for use as they waste to nothing.
[i]Overload:[/i] By taking advantage of her gross amount of reiatsu, Kotohime can do something quite simple to anyone who is both currently affected by the reiatsu spikes and is weak enough in comparison to her current state: she can make them explode. Draining but effective.

[b]Bankai:[/b] [i]BOBSWORD ULTIMATE[/i]: Directly weaponising her reiatsu, the released form is naught more than a ring--but any restraint to her reiatsu ends, with Kotohime's full power manifesting as a malefic green cloud steadily spreading as it consumes. It retains all her shikai abilities, but it also acts as a smothering blanket devouring all ephemeral effects, forcing anyone wishing to defeat the captain-commander to do so quickly, and in melee before they become simply a reiatsu battery.
Whilst she can direct it to an extent, this is only to create a safe 'bubble' around a select few, and any else that get caught will be drained, growing the cloud further. Whether it would stop due to its owner exploding from the power, or consume all within Soul Society, is not something she wishes to test.
