Oh, he comes with Safety/Lava-Fall Megatron? I did not know that. Interesting.
I've been leaning towards buying Soundblaster before Takara Soundwave all along, but it'll still be a while before I save up.
And for once, my desire for a KO of this Ratbat isn't about the price as much as that while I want all my cassettes to be the same size (that's kind of the point) and therefore see those enlarged KO cassettes as a total waste, this Dery-accurate Ratbat is the one and only potential exception, since Marvel Ratbat was usually 2-4 times larger than the other cassettes in robot/animal mode. His TF Universe entry also mentions him being able to achieve two different sizes in bat mode; was he the only non-Insecticon to have that ability explicitly stated back in the day? (Overkill doesn't count, as his TFU entry says it happens to him by accident)
