L-1 FE Binder

The L-1 FE Binder is a Wonder Weapon featured in Lament of the Dead and Shinin no meiyo.

Overview
It is currently unknown who made it, however quotes from the Demonic Announcer in Aether Zone suggests that he made it in life but was killed by it's immense power. However as time has passed, it's energy has become stable.

It is the most unique Wonder Weapon in the Zombies series, as it can turn into any previous non-tactical Wonder Weapon at random. The only difference in appearence is that the Wonder Weapon will appear green with multiple vines slowly wrapping around it. Due to it's unique nature, all Wonder Weapons that it turns into have infinite ammo at the cost of all of them having the same reload time. When Pack-A-Punched, it becomes the Alexstrasza's Vengeance, featuring the abilities of all the Wonder Weapon's upgraded effects. The Wunderwaffe DG-2 has the World at War version. It should be noted that no matter weapon it is currently, it will always say L-1 FE Binder upon use.

Shinin no meiyo
In Shinin no meiyo, it returns for the alternate four (and the other four once the Easter Egg has been progressed). The L1-FE Binder appears in the Mystery Box of Revenge of the Silverback and Lament of the Dead. Although not much has changed, it lacks the ability to turn into the Zeit-Wunderwaffe, instead it will only become the Zeit-Beschleuniger. Due to this fact, if the L-1 FE Binder is received in the Mystery Box while Lava Sale is on, all of the Wonder Weapons become Wonder Punched. The L-1 FE Binder is the only Wonder Weapon not terminated by completing the easter egg due to the fact that it doesn't run on Element 115. It has a 1% chance of dropping from the Mystery Box after the Easter Egg is complete.

Trivia

 * 'L-1 FE Binder translates to Life Binder''. The name Alexstrasza's Vengeance is a reference to this.
