Why So Many Upgrades?

Kira’s upgrade tree is designed to reflect his JoJo’s Bizarre Adventure abilities:

  • Stray Cat → AOE bubble bombs
  • Sheer Heart Attack → Auto-targeting tank
  • Bites The Dust → Game-resetting explosion mechanic
  • Eat The Dirt → Endgame nuke ability (unlocked at max upgrade)

Each stage not only boosts stats but also layers on new mechanics, making him one of the more complex and rewarding units to fully upgrade.
