I can't help but look at the dual-wielding guy and think it's Riku even though the hair is blonde, not white/silver. Still cool nonetheless.
That symbol only goes on the heartless that ansem created, it's his symbol, not the heartless symbol.

Part of Report 3
As a start, I have built a device that artificially creates Heartless. By recreating the conditions that spawn the Heartless naturally, I should be able to produce them artificially. This device is the culmination of all my research thus far. The machine's test run successfully created a Heartless. This may be a step toward creating a heart from nothing. The artificially and naturally created Heartless showed nearly identical traits. But the two types remain distinct for the purpose of the experiment. So, I will mark the ones that are created artificially.
