Memory Shard (black)

The Memory Shard (black) is an optional upgrade for Shadow the Hedgehog in Sonic the Hedgehog (2006). It is a special type of equipment that allows Shadow to activate his Chaos Boost Level 3 once he has filled up his Action Gauge. This grants Shadow the Chaos Blast attack, an explosion of Chaos Energy.
