Now I know that they're kids toys, but... Seriously, do any adult collectors appreciate Transformers that makes noise? I kind of like that Universe Silverbolt makes the classic transformation sound when his head pops up, but the electronics in my Powerglide were so messed up that eventually the sound effects became stuck on and wouldn't turn off until I took out the batteries. ROTF Leader Prime almost got his batteries taken out before he was transformed properly thanks to unnecessarily introducing himself over and over and over as I tried to transform his chestal region. The G2 seekers' sound effects boxes are kind of funny. There are two buttons. Pressing one makes a machine gun noise for a tenth of a second, unless held down. Pressing the other makes a jet taking off noise, which lasts approximately four days and scares our ferret. Lights are a little cooler, but only a little. I like MP Megatron's red light of doom. MP Grimlock's gun/sword/hand light up gimmick is nice, but I would've still preferred he be able to shoot the bird like Unicron. Speaking of Unicron, cool glowing hand, bro. Universe Onslaught's eyes are kind of sweet, actually. Other than that though, I could do without sound or voice and be very happy. Actually, having batteries in my toys worries me because I know some sad day in the future I will have to remove the batteries from all my Transformers so that they don't leak battery acid. RID Prime in particular keeps me up at night for this reason. Missiles are my least favorite gimmick of all time. American G1 reissues either come with dysfunctional missile launchers (that's cool) or ludicrously oversized missiles. Newer toys like 07 movie Starscream come with a half dozen missiles, one of which I spent 20 minutes looking for only to find on the kitchen floor. I'm slightly afraid of blinding myself any time I look at an armed Transformer. The only missiles I can think of that I actually like are Animated Swindles, because it has those cool orange and black stripes when loaded, and original G1 seekers' short missiles, because they blend in well with the launcher and look like little bombs. G1 Prowl (and friends) and Hound's missile launchers are cool for character decoration, but other than that I mostly leave my missiles in ziplock bags.
