From prototype to actual-item, here comes the "Eggman Robot Battle Set" from Jakks Pacific.
This is the 2nd playset in their line, with the first being Green Hill Loop. This one promises boss battle action, when you can launch the classic Sonic figure at the final boss of Sonic 2, the giant Eggman robot. It looks good in the big window packaging here, where you can clearly see all the items you get and the illustration shows you how it works. The corners are solid, which is another good move by JP. This is good for MIB collectors or to take it out. Their only problem being that they used Modern Sonic on there. Notice it is part of the 30th celebration, with the red rectangle, as well.

In the gallary you can find the factory photos of it out of the package so you can see what it does. The robo figure is clearly pose-able, although it also has 'pop apart action' as evidenced by the box art. The Sonic figure is of him in a spin / rolled up so that he can be launched with the spring loaded catapult item. It looks like if you hit the center panel (as you had to do in the game) that it changes from normal to 'battle damage' which is a common action figure trait that works well. (Who started it, was it He-man?) It would be a fun goal to try and shoot him to switch the panel. The catapult is themed for the sort of 'death egg' design look with caution-stripe base, bolts & gray metal looking construction. It makes sense as something to include.
This looks like a good playset once again. The boss looks like it does in the game, the action element is fun, it looks like it will display well, and the box is very appropriate. This will be a good one to collect.

Here's what the box for the Egg Robot Battle Set looks like.
It's quite a good one, with all the features you'd want. Top-windowing to let light in for better MIB display, totally enclosed without fiddly bits to attract damage & good big window. The back nicely illustrates the features like the damage panel, the fly-off spike 'hands', the backpack 'jets' action/movement and how to use the catapult thing to launch the Sonic figure at it. It explains how each thing works in 3 languages. Then, at the bottom another good move is showing what else there is to collect. Always helpful!
The sides have 1 partial window/repeat of what it does or running Modern Sonic even though this is a classic thing. (Notice it also has modern logo all over as well)

Opinion Zone:
Get this! It may technically be on their 'small line' because the Sonic is small & it is a playset but it is BIG. This weighs 3 pounds by itself so nobody was skimping on materials. Big action (esp pop-apart) toys like this ALWAYS become rare in the future! It's about 39.99 in Target (Confirmed August) so be sure to grab it right away if you want it.

It's a big, colorful game-like thing that is accurate and has fun play features. Pop-apart things get easily lost by kids and large heavy objects don't store well for non-fans so expect prices to shoot up as soon as this goes off shelves. Jakks Pacific scores again with another fun and reasonably enough priced playset. This item is in the SonicGear collection

Here is the turn-around for the moto bug badnik figure. It's technically on the small line figures, but you could probably use this to play with the 5 inch figures too because most badniks weren't totally huge in the games. What's neat here is that it secretly comes with a transparent plastic base.

The base is near-completely invisible in the packaging. There is 1 hole in the thick rubber of the tire that fits on a peg on the clear base. The back has a wedge to catch it so that the wheel doesn't just let it tip right over (As it otherwise would) The wheel is a good quality, solid feel. It rolls easily. The little 'arms' are the action bit, you can pose them a little. There's a texture for the vent in the back, and the whole thing is quite quality for a 5 dollar item. Opinion Zone: Buy 2 and use 'em for playset display!
