War Hammer Titan
I was inspired by the Kogarasumaru
A Kogarasumaru is a double sided katana but I put twist in the creation. It would be made from high durable metals that allow it to pierce through titans with powerful blows which cause small explosions when in contact because of a special sticky gunpowder compound. The weapon also has a feature that allows it to fire the blade from the hilt with explosive resistant string that is highly durable attaching them so that it allows heavy damage on any titan that it collided with from a distance without you having to retrieve the blade.( there are triggers on the hilt to fire the blades). The one fall back is that the user has to have stable ground so that the titan can’t pull you towards you and kill you. But if using it at melee close combat then it is very helpful. I know that there are many swords in the Attack on Titan series but I thought that this idea was cool. Thanks for taking a look at my idea!
