Robot Alchemic Drive [PSX]
As soon as you start getting money from killing Volgara, try to put as much as possible into making your character and Vavel more powerful by purchasing new attacks, thicker armor, and more ammunition for your weapons. Vavel's power is average at the start of the game, but if you build it up completely, it will be combat superior to all of the other enemies and Meganites, including Osmodeous.
Vavel: Volcanic mode:
Vavel's Volcanic mode has the ability will allow you twice as much power in the normal mode. This can be very helpful if you are losing a fight. If you are not very skilled at controlling Vavel yet, you should only use it as a last resort. If you start off in volcanic mode and cannot control Vavel well enough, you may run out of time and lose the fight. This is also the same with Vavel's Genesis mode, only you gain about four times normal power.
Vavel: Double hit:
Initiate the Gravity Zero technique (when crouching, Left Analog-stick Up + Right Analog-stick Up; this is a bought technique) and knock the opponent up. As soon as Vavel stands up, do a hard punch (press either Analog-stick Away then Forward). If you timed correctly, Vavel will hit the opponent away.
To get a better view and control of your mech while it fights, use your Gravity Boost (on the "Hero mode", hold Circle) and boost your way to the top of a nearby building. You can now get a much better view of your mech and the fight that it is in.
