My advice, stick with the original song, but it would be interesting to see that animation you mentioned.

Yeah, I'm looking into someone who will do one for me.

I'm kinda thinking about having the animated intro in synch with the audio or something like that.

I'm also writing this down onto a document since I just got a good idea and I don't want to lose it:
Here's the opening of the song:
Optimus and Megatron from Transformers Prime are fighting each other, and Megs drops Optimus to the ground. Before Megatron can kill him, Kamen Rider Fourze blasts in with his Rocket/Drill Limit Break and knocks out Megatron. Fourze and Optimus then fist-bump. They turn around to see Omega-ShoutMon/he gives a thumbs-up, GouJyuJin/from Gokaiger, the Samurai Rangers in Mega Mode, Sonic and Shadow, the original BeetleBorgs and the BeetleBorgs Metallix, Servo/From Denkou Choujin GridMan, UltraMan Zero and Ben 10's Way-Big/Since Way-Big looks like an UltraMan, Spiderman swinging into the scene, Lion-O, Ash with Pikachu, MegaMan X with Zero, BatMan/Using the armor from BatMan Beyond, Super-Activated Robot-Boy, Drago from Bakugan, and finally Fire-1 X from Tomica Hero Rescue Fire. They then all turn to see a huge figure in shadows/It's Galactus but He's massively shadowed out. The group then all use their special attacks on the huge figure. To finish the intro, an animated Zeltrax/Yours Truly uses the group of heroes as platforms and Optimus Thrusts me forward, where I punch towards the screen/at that point the scene shatters to reveal my show logo/title credits and then fades to black.

What do you think?
