Originally, when Alex learnt of the fact that Stacy's game character was a vampire, and that, she was just a new player in the DFG. He thought he could help her by revealing a few of the skills he used during his time as VampAlex; the game character of the famous Alex Stale.
As someone who has a great knowledge of how things works in the DFG, he knew how difficult it is for a new player to rise through ranks in the DFG. Now that most of the players in the DFG are using vampire as their game characters, the competition has become higher than before.
Apart from clawing and swiping at their enemies, vampire characters can also use vampiric powers, like the Time freeze and light blast that Alex's character uses.
