Now here's something wierd.
This is "Sonic Jetpack Heli", and it's a flying action figure. Well, more like a static figure that flies itself around like one of those novelty tiny RC helicopters. It's a strange concept, but he probably did try out a jetpack at some point in the show's wacky run, and this thing is here to try to capitalize on it. The Sonic figure has a gray jetpack, the control joysticks molded into the hands & is just 'standing there' to provide a stable base. The jetpack has the double rotor plus stablizing topper thing on the metal rod coming out of it. There's a barely-branded joystick type controller (only 2 sticks, no buttons) with tiny Boom logo at the top to try and control him. The figure isn't super...the head is very round with the spikes mashed down (For the sculpt) & the eyes are little dots so he looks suspicious or wierd. The ears are also made smaller. Here you can see what it looked like new in the package as well as loose.
As you can also see...it likely wasn't very popular as it's clearancing out for a 2nd time according to the sticker. You can often find tons of 'non flying type' characters as these cheapo 'helicopters' that (reportedly) aren't very fun to play with nor control so it's a little odd to see Sonic being stooped down into one.
