Which game on Toonami.com was it where TOM turned evil? I remember him gasping with his hands on his stomach, it sounded painful, and then he started giggling evilly.
I'm 85% sure this was the 5th level of Trapped in Hyperspace. I played a lot from ages six to eight, and it was my favorite game on Toonami.com, so it had to be from there. The only clear things I remember about the game now are Swayzak's freakout at the end, and SARA telling me to fix the NAFT system in level 2. And of course TOM being infected.
