Like dependent plants, Knives does not require food, water, or sleep to survive, and he gets all his energy directly from the Core. Conrad calls Knives the ultimate life form. It is implied by Rem that Knives is able to produce like a dependent plant can, though what he can produce while on SEEDS05 is not specified. After SEEDS05, we only see him produce his knives and cloak.
The SEEDS05 database contains entries for Vash, Knives, and Tesla.
All three are listed under Project Code type-T. Their category is Independents. All three were 55 lb at time of entry. Vash and Knives were 4 ft 1 in, and Tesla was 4 ft 4 in.
