Government: Asks Gerald to create an immortal being.

Gerald gave Shadow a soul so that humanity would not abuse his power for monstrous acts. Little did Gerald know that in the end, he himself was still only human. It is fortunate for him that he truly was a genius, for his design allowed for his own act of madness to be stopped. For was it not for Shadow's capacity for emotion, Shadow would have become the very thing Gerald feared GUN would make him. A tool for destruction.

I feel bad for the Biolizard. Imagine being this massive thing that can't move and you're being kept alive in a sealed room. What a miserable existence.

I wouldn’t consider Gerald’s death an “execution” considering he didn’t get a trial.

The “Sonic should never take itself seriously” crowd just don’t know how to have fun

This story is exactly why Sonic X is my favorite Sonic show. Even the 4kids version of this storyline conveys the depth and sorrow of Shadow's story.

The line by Professor Gerald, "You ungrateful humans who took everything away from me will feel my loss and despair..." still chills me to my core to this day.

I hate when people say Sonic shouldn't be dark and serious, when the series can do It well, i just wish that the new game has an good...the same goes to other franchises such as Mario

One of the reasons i LOVED shadow the hedgehog is because it reminds you that Gerald was a good person at one point. The whole reason Gerald created the Eclipse cannon was as a fail safe against Black Doom, he knew Black Doom's return to Claim shadow was only a matter of time. Were it not for the Eclipse canon, Black Comet would have never been destroyed.

Knowing that Shadow was inadvertently based off of Sonic really changes my view of Shadow calling Sonic the real ultimate lifeform during the final battle, cause I originally thought that it was a random line solely meant to sound cool, so it’s cool to know that there was actual meaning behind it.

The fact that GUN STILL uses those canister things in their present day tech. Still using Gerald's tech even after they took everything from the man

Realizing that Gerald made shadow's soul based of Maria, makes me feel more bad of how Sonic team portrays him now days (and back in the shadow the hedgehog game)

It would be interesting to see how much of this plot line gets adapted in Sonic 3.
