Rayden is my favourite character:

Watching events unfold from high above, the thunder god realises
the grim intentions of Shao Kahn. After warning the remaining
members of the Shaolin Tournament, Raiden soon disappears. He is
believed to have ventured into the Outworld alone.
Ending

Familiar with Shang Tsung's lies and Shao Kahn's brutality, Raiden
accepts their challenge to compete in an Outworld tournament. He is
well aware of their scheme to unbalance the furies and invade the
earth realm. Raiden vows to use all his might to end their
treachery.
By winning the tournament, Raiden destroys Shao Kahn and all his
minions. He also destroys the dimensional gates which would have
been their passageway to the earth realm.
