Items in Telefang 1

Items in Telefang 1 have a few specific uses.

They can be used to fusion evolve certain Denjuu, although their stats, with the main exception of the Denma stats, will be lower than they would be if they naturally evolved.
The Phone Card can be used to extract DNA from specific Denjuu. Depending on the Denjuu, it may extract a Biolent 3, a Grapplite 9, or a Gigaia 00.
The Biolent 3, Grapplite 9, and Gigaia 00 can be used to lab evolve some Denjuu.
Nearly every item in the game can be used to give experience to Denjuu.
Nearly every item in the game can be given as a gift to any Denjuu. Doing so will raise a small amount (approximately 2-6) of FD. The Denjuu's response to each item seems to mostly be based on its monetary value, and they will refuse to take certain items altogether (such as plot-specific items, or keys.) The Kickboard is the best gift, giving 26 FD.
