Very awesome.
I love this series, and the episode itself was worth the wait. I'm not entirely sure where the Axem Rangers X came from, or what they are, and I think this episode could have done without them, to be perfectly honest. I mean, I'd find it hard to make a fight scene with 14 characters having an almighty free-for-all.
Some of the effects were VERY nice, especially that effect with Shadow when he was beating the snot out of one of the rangers. I hope this same fight doesn't drag on for too long in Ep.6, mainly because I'd like to see someone (ie. Mario or the Koopa Bros ringleader) having a one-on-one with Mecha Sonic. Also, the good guys better win that chaos emerald. :D
I can't wait for Episode 6. Keep up the awesome work.
