Sonic loses his Boost, but gets back his Spin Dash. In Sonic Generations, Sonic taught his past self his Air Dash; conversely, meeting his past self has reminded Sonic of the Spin Dash!
When Dr. Eggman speaks to the Zeti about eating their black hearts during his little freak-out moment, it seems really out of place for him, but then I remembered something. Zomom spoke several times about eating Sonic and Eggman, and even Zeena mentioned eating Sonic at one point, so they are probably a race of cannibals. Dr. Eggman was speaking to them in terms they could understand. I'd say that qualifies as fridge brilliance, and maybe a little fridge horror too.
Among the new Wisps showing up in Lost World, there's Indigo Asteroid and Crimson Eagle, which in a sense replace Purple Frenzy and Violet Void from Colors. If you recall, the Frenzy and Void wisps were Nega-Wisps, corrupted by Eggman draining them of their Hyper-go-on energy. Due to the theming of the two - an animal and a space-themed object - as well as their general purpose, it can be assumed that the Crimson and Asteroid wisps are "purified" versions of the Nega-Wisps.
Despite their roles as a Knight of Cerebus, the majority of the Deadly Six are rather pitifully easy enemies to defeat, with the majority of them taking anywhere between 2 to 3 hits, something that would be rather low end even by the standards of past Sonic bosses. But it actually makes sense; the Deadly Six are the strongest beings on Lost Hex...but that doesn't really mean much when the majority of the denizens on the Lost Hex are non-combatants or wild animals. It's possible that Sonic and Eggman are the first time they've ever fought against enemies who are their equal or far stronger than they were. Rather tellingly, the only Deadly Six who poses anything resembling a threat is Zavok, not just because he's the head honcho, but because his domain is the most dangerous location of all of them, and thus he'd HAVE to actually be quite tough.
When the Deadly Six drain the life out of the planet, Amy and Knuckles lose their lives as well. Then you remember that not only is this affecting the whole planet, but is very likely affecting all of Sonic's friends there as well. Shadow, Rouge, Professor Pickle, Vanilla, Cream... who's to say the Gaias aren't affected as well? Poor Chip, and even Dark Gaia.
THANK GOD anyone and everyone affected got their lifeforce back by the end of the game.
The trap that captures Tails was originally meant for Sonic. The horror comes at the realization that if it caught its intended target, who is less smart than Tails and doesn't have his fox tails, the roboticization would have succeeded.
What exactly did Master Zik teach the Deadly Six to make them the way they are now?
There is the possibility that the Deadly Six are naturally aggresive.
The mech Eggman uses is powered by stolen life force. Even its massive cape is made of such. Which brings this question: how many living beings died for Eggman to use as a mech? He clearly wasn't stingy about stealing all this life force, since he used some to make his mech look cooler...
Again, thank God everyone got their life force back.
