I seriously wanted to change my profile name to Infinity's End.
My own character. The God of Evil.
When I listen to this, I imagine 5 heroes coming to his fortress to destroy him. After introductions, Infinity's End starts dropping down large rocks on the heroes. Then he sends waves of fire. After that, it's fireballs. Then pillars of fire rise up from the ground to destroy the heroes. When he finds out his attack isn't working, he switches to a more powerful form of attack. Darkness attacks. These do not defeat the heroes either. Each of them has a magical shield which repels evil and darkness. Infinity's End eventually switches to his most powerful attack, Infinity attacks. First, he sends out bolts of Infinity energy to destroy the heroes. It actually kills one hero. Then, he launches a shockwave, killing another one. After that, he uses his second most powerful attack, Infinity Nova. This kills another hero. After that, Infinity's End uses his ultimate attack, Infinity Blast. This shatters the shields, and kills the second last hero. The final hero is almost killed. He takes the 5 swords, and fuses them into the Blade of Light. Infinity's End takes out the Blade of Destruction. They fight, and the hero wins. Infinity's End is banished to the realm of darkness, and an era of peace follows.
How's that for your great battle?
