Tout simplement =p :
* Koushiryoku Beam:
Mazinger Z can channel pure Photonic Energy through its eyes, unleashing a pair of powerful lasers, which are said to be equal to 10 tons of explosives. This was originally considered Mazinger Z's weakest attack, however, in Shin Mazinger the power of this attacked is greatly magnified to the point where it can now be considered the strongest.
* Missile Punch:
Mazinger Z mounts a missile launch bay in its belly, which can store several missiles.
* Rocket Punch:
Mazinger Z's eponymous attack; it fires off its forearm like a missile, punching straight through an enemy before returning and docking with the elbow again.
* Rust Hurricane:
The powerful turbines in Mazinger Z's head create gale-force winds, launching them through the mouth grill. The attack includes highly corrosive particles (thought to be ionized hydrogen), almost instantaneously causing an enemy to rust over and fall apart.
* Breast Fire:
The large red fins on Mazinger Z's chest act as heat sinks for its Photonic Energy reactor. Mazinger Z can fire off this stored thermal energy as a powerful, 30,000 degree white-hot beam that melts almost anything. In the Super Robot Wars series, Kouji and Tetsuya Tsurugi can use the Breast Fire and Breast Burn respectively in the Double Burning Fire attack, which they use in the MX version of the Final Dynamic Special (also involving Grendizer and a Getter).
* Kyoukagata Rocket Punch:
Mazinger Z's Rocket Punch was later reinforced with stronger armor, giving it a more powerful punch.
* Iron Cutter:
An improved Rocket Punch in which the forearm sprouts a pair of axe-like blades, allowing it to cut and slash as well as bludgeon. This is the only weapon in Mazinger Z:s arsenal which can damage Super-alloy Z.
* Drill Missile:
A barrage of small, needle-like missiles fired from ports in Mazinger's upper arms. This attack was typically performed after the Rocket Punch but before the forearm had returned.
* Daisharin Rocket Punch:
Mazinger Z spins its arms rapidly, building up momentum before firing off both fists in standard Rocket Punch fashion.
* Reitou Beam:
Mazinger unleashes a blast of intense cold; this attack was alternately fired from the mouth grill or the spikes on the sides of Mazinger's head.
* Finger Missile:
A rarely-used attack where Mazinger fires the last joint of its fingers as miniature missiles.
