A Tube of N-th Metal Feather Polymer - A special polymer designed to convert living feathers to a tough metaloid with the approximate properties of stainless steel - this tube has enough to apply to 6 large feathers such as found in the wing tips or tail. Originally developed in a group of obscure universes by some more hippy than usual Thanagarians, the metal blades produced also have the advantage of ignoring magical defences.

A NeoSoviet Assault Vest and Control Watch - This is one a small run of production produced on an earth with an accelerated timeline - the NeoSoviet Empire of the Year 2114 did research into how to maximize the efficiency of their army, they had large numbers of men but little training. This vest in addition to being an advanced piece of armour resistant to 98% of standard firearms, and capable of nullifying most energy weapons down a level (shrugs off stun blasts, turns kill blasts to stuns, and lets the body survive for identification for disintegrations) but it is primarily designed to override the soldier's own mental functions and replace them with an optimised one. A person wearing this vest will exactly follow all orders given to them without question, and function as a fully trained and adapted soldier immediately. Wearing the watch and the vest at once will result in brain damage.
