The Single-Layered Extreme (一重の極み Hitoe no kiwami?) is a Level Up Item for Silver the Hedgehog in Sonic the Hedgehog (2006).


The Single-Layered Extreme is an item of unknown appearance. It is a special type of equipment that, once obtained, allows Silver to perform the Hold Smash which throws everything Silver has grabbed with his Psychokinesis in a single throw.


The Single-Layered Extreme becomes available after Silver clears the first Iblis boss fight and arrives in the Forest. It can then bought at the local Shop for 200 Rings.
