Put your detective skills to the test

We can rule out whitespace inkmatas since we can see a large wound on his chest, bloodstone simply wouldn't do that. Same goes for the carrot since it doesn't have a sword.

Den can be ruled out as well, since I don't imagine an axe would make that type of wound

Leo I'm not sure about since I haven't heard of them before so I'll just rule them out.

That leaves the tyrant and exiled one.

Both very strong, both wield swords, but I'm pretty sure the tyrant would've been the one to do it.

Xander was involved in the battle of the citadel, and helped the collector defeat the tyrant. So of course he would want him dead.

I'm gonna say Tyrant because Xander was protecting Seven, and one of those two could care less about Seven.

clearly
carrot

Carrot, i can tell based on that face

(accidentally posted the comment when it wasn't finished)

Welp gotta ask questions first

the exiled one,
Most people would say leo because of the blood, but a wound that smooth wouldnt match the one found on xander, machetes arent known to produce clean cuts due to the inverse curve on their blade, it would likely be a katana, and whos the only one who has tha weapon?
Exiled buddy

Leo uses the gold saber
(The gold saber is a weapon that was made by Densetsu. The gold saber users gain enhanced power, enhanced senses, enhanced healing, and reduced aging)

probably need a picture of the weapon

im still sticking with my answer, sabers are very flimsy and lightweight, thats why most conquestors switched to firearms during the spanish revolution, a deep wound that could produce that much blood would required a smooth, yet still heavy blade, and the exiled ones katana fits that category perfectly

Not all sabers are flimsy

listen, if you want me to choose leo, just say it

I need to say more about Leo first

tyrant

Prolly WS Inky

Well probably Leo, he has blood on his blade, and the gash wound would match the cut. It's definitely not Whitespace Inkmatas, because I think she consumes blood, and the scene depicts blood. The gash wound wouldn't match with the tyrants blade.

Well how do we know it's xander's blood
