And here I come. Prepare for an overload of No More Heroes stuff.
Dark Star's Lightsaber Dragon: It's a LIGHTSABER DRAGON! How more badass can you get!?
Speed Buster's Wave Motion Cannon: Okay, I don't know what it's called, but that thing is pretty powerful too, you have to admit.
Letz Shake's Earthquake Machine: With this, I'd be untouchable by melee weapons, as it makes small Earthquakes to slaughter opponents.
Destroyman's... Crotch Cannon: Can anyone say Kamehameha ripoff?
Travis Touchdown's Beam Katana: It's just made of pure awesome.
Henry's Beam Claymore: Same.
Glastonbery (Sp?): It's a giant robot. Like a gundam, a ripoff.
Really, just give me anything from No More Heroes, and I'll be happy.
