Its always fun
haha I used to always play as fire witch until Christian learner about her weakness. Her fireball attack(I forget the name Atm) is rather inaccurate
BUT she can fly highest AND respawn her 'mp'(again I forget what its really called) in the air and shes the only one who can do that xD. So she can shoot just fly around without ever having to land unlike dark angel, kill cycle, and wasp. Also beta razor can I believe but hes one of the two the unlockable awesome version of razorfane (the arcanes is mega prana who's the mega of pranadevil)

Now I tend to play as mogalin rider or ecton. I favor the arcanes.
Ill spoil the list of characters

Arcanes:

Dark Angel: Humanoid character with wings. Can fire eye lasers, deliver a shockwave attack or place a crystal that heals him gradually.
Brontu: Resembles a six-legged rhino. Can charge at high speed for a ram attack, roar a shockwave into the enemy, or place toxic gas clouds IN SHORT "UMUUTOT" (farting in english).
Ecton: Humanoid devil. Can place net traps, can spray Baygon to the enemy, drain opponent's health to restore his own and whip a beam that damages and slows the enemy.
Fire Witch: Flying woman made of fire. Can place patches of fire, shoot fire balls and dive bomb the enemy. After the dive-bomb she needs a few seconds to get back up.
Mogalin Rider: Humanoid woman riding a bipedal monster known as a Mogalin. Only character with four moves; can fire a quick magic beam, switch places with opponent, use a weak tongue attack or swallow a power-up to deliver a homing belch attack when tongue attack is pressed again.
Magus Lizard: Humanoid lizard with mage clothes and a sword. Can swipe his sword, summon homing ravens, or summon meteors.
Prana Devil: Demon creature resembling a scrawny lizard. Can bite opponent, fire spit balls and lay eggs that hatch into Prana chicks. There can only be 3 chicks in the arena at one time and they are easily slain.
Megaprana (Secret Character): more powerful version of the Prana Devil. Has the same moves, but are all more powerful and can jump much higher too.

Teknos:

Jaeger: Tank-like droid fitted with arms. Can shoot homing missiles, fire a powerful laser or deliver a heavy punch.
Killcycle: Humanoid cybernetically attached to a flying jetcycle. Can fire plasma blasts, drop bombs, or sacrifice its life to deliver heavy damage.
Mantis: Mechanical insectoid robot. Can lay suction-vortices, crush the enemy with his mandibles or launch homing techno-tics that take health from opponent back to Mantis.
Quicksilver: Humanoid woman similar to the T-1000. Can fire orbs, deliver a slice attack, or use shield that can protect against any attack and reflect projectiles.
Tesla Lord: Humanoid carrying electricity conducting staff and backpack. Can teleport to a random spot, fire a shock beam or plant a crystal that shoots lightning balls.
Razorfane: Human brain in a mechanical body with circular saws and spikes. Can fire ripsaws, place bladewalls (saw-barriers) or spin on the spot for a close range attack.
Wasp: Cyborg woman outfitted with hovering wings and blaster. Can hover, freeze enemies, drain their health (giving it to her) and fire a gun.
BetaRazor (Secret character): Razorfane with twice the health, bigger energy meter, thrusters, fires energy blade circular saws, razorfane's spin-on-the-spot and energy field slam attack similar to Fire Witch's (but without the slow recovery).

Also it gets confusing to figure out who is weak against who and who is strong against who but the game tells you if you need to know
XD
