Report's match against XD during T3h L33t W4rz—chunking the villain with his own move to create an IronicKarmic Death as well as marking a triumphant first appearance of his Superpowered Evil Side—after a particularly epic speech.
The speech itself was awesome.
Report: "Y'know, five minutes ago I was so angry that I wanted to tear you limb from limb, duct-tape you back together, beat you to death, then revive you and beat you to death again. But that was then, and this is now, so I don't wanna do that anymore."
XD: 50, ur 90|\||\|4 137 |v|3 0|=|=? (So, you're gonna let me off?)
Report: "Nope, you're still gonna die a gory and excessively violent death. But see, four-and-a-half minutes ago, I learned this." *hand starts to glow* "Say 'hi' to Aelf for me."
This was followed by Viel's first line—which happens to be his Catch Phrase:
Viel: "Karma's a bitch, ain't she?"
Ere's fight against XD was awesome as well, even though she lost. She'd probably have won if XD wasn't hax.
Axel's Big Damn Heroes moment in the third part of Giga-Nippon. Made even more awesome by his incoherent rage-babble.
