"Nothing ruins an enemy's day like a thermonuclear hand grenade."

―Slogan on GrummelNet weapon vendor description.^[src]

The Fusion Grenade was a GrummelNet weapon that allowed the user to lob powerful thermonuclear grenades at enemies. The grenades did not explode on contact, but exploded one second after being thrown, similar to the effect gained by the Timed Trigger Constructo Mod. The grenades' blast radius, even without upgrades, was massive and could easily deal with any early on enemies. The Fusion Grenade upgraded into the Fusion Bomb at V5, which added GrummelNet's patented "Intelli-Seeking Pyrocidic Nitroballs" to each grenade.

Ratchet & Clank Future: Tools of DestructionEdit

Ratchet started the game with the Fusion Grenade in his arsenal, along with his Combuster. Each grenade dealt 150 damage without Raritanium upgrades, making it the most powerful weapon early on. However, like all of the weapons Ratchet started with in previous games, it eventually became obsolete in power. The special Raritanium upgrade for this weapon was Concussion Detonators, which would knock down enemies that were not killed in each blast for a longer time.

DamageEdit

Damage increased by 15% of previous damage each upgrade. Weapon damage without Raritanium upgrades:

• V1: 150
• V2: 173
• V3: 198
• V4: 228
• V5: 262

Raritanium upgradesEdit

• More Ammo x2: cost 100 Raritanium each, added one grenade to ammo capacity
• More Bolts x2: cost 250 Raritanium each
• More Damage x3: cost 200 Raritanium each, added 5% of current damage
• Bigger Area x2: costs 400 Raritanium each
• Special Upgrade: Concussion Detonators, knocked down enemies not killed in the blast for a longer time; cost 300 Raritanium

Ratchet & Clank: Quest for BootyEdit

Ratchet started the game with the Fusion Grenade, but it was lost in the Azorean Sea shortly after when Rusty Pete shot Talwyn and him to Hoolefar Island. Pete later returned the Fusion Grenade along with the Combuster to Ratchet after Pete resurrected Slag and Darkwater in Morrow Caverns. It started at V3 and upgraded into the Fusion Bomb at V5. Surprisingly, the Fusion Bomb in Quest for Booty lacked the bomblets that the Fusion Bomb had in Tools of Destruction.

Location of the Concussion DetonatorsEdit

The Concussion Detonators upgrade could be found in the underwater tunnel in the bay of Hoolefar Island. To get it, dive into the bay and enter the underwater tunnel, avoiding the mines. Jump out of the water, and smash the crates in front of you. Blow down the gate with a Fusion Grenade, and behind it was the Concussion Detonators upgrade.

DamageEdit

• V3: 154
• V4: 180
• V5: 216

TriviaEdit

• If Ratchet equipped a skin, the bomb would appear but not the glove.
