Deepa versus Kisame🌴
Deepa can hurt Kisame but not enough to kill the Shark. Kisame can heal himself with Samehada, and while Deepa can use his Iron shield to protect himself from a fatal blow, Kisame can take his chakra, imprisone him in a Water Jail, drown him in the water done and harass him with Water Shark Bomb.
🔪Kisame wins this.
Deepa versus Kakuzu🌴
Deepa versus Kakuzu is interesting because both of them can use Iron as a shield and both of them mostly attack via a distance.
Plus, Deepa Iron bullets are very well fitting to pierce Kakuzu Hearts.
Kakuzu can warm the Iron if Deepa shield until he die.
🔪So equality on that one.
