Eggman
And the Chaos Emeralds too, right?
The last thing you would expect is a snake and power crystals.
Sonic boom is worse than ‘06. At least '06 tried. They were smart enough to have robotnik be egg shaped and be the main villain. they were smart enough to make the chaos emeralds be a plot device.
The biggest problem with sonic boom is that they added stuff that didn’t need to be added. They added characters and plot devices that are the same as the old characters and plot devices while the old character and plot devices were still preasent.
Link between worlds did something similar by having the dude who looked like ganon steal the sages and the triforce because their triforce was destroyed but at least ganon was dead at the time so they have a reason to add not ganon.
If robotnik was dead and the chaos emeralds were destroyed, then I could understand lyric and the power crystals but they aren’t.
