Custom Robo Arena/Part Combinations

Trap and zap
This is an effective combo that can be used relatively early in the game. Use bombs and pods to trap the foe, then use the thunderbolt gun to hit, and use your physical attack while the enemy is stunned. Use bombs on the enemy or shoot again if the enemy is too far away for a physical attack.
 * Robo: swift.
 * Gun: thunderbolt gun.
 * Bomb: any bomb that can box in enemies, making them easier to hit. The winder bomb is a good bet.
 * Pod: your choice.
 * Legs: formula legs are recommended, but not necessary.

Stun Gun Combo
A powerful combo that can take down even the toughest opponents when used correctly. Use bombs to box enemies in, then use great ground speed or quick and unpredictable air dashes to get close enough to use the stun gun. Hit with the stun gun, then use your physical attack. Once the enemy is down, use a combination of more stun gun shots, physical attacks, and wall pods to dole out the damage.
 * Robo: any fast robo with a physical attack that is powerful and can hit foes right next to you (any little sprinter or raider with the right kind of physical attack will work, like the robin. Strike vanishers, burning beasts, and wild soldiers are good for approaching from the air. The leon burning beast is a good one.)
 * Gun: stun gun.
 * Bomb: your choice, but the winder bomb is a good bet.
 * Pod: wall pod.
 * Legs: formula (for ground models) or any leg that increases the speed or distance of your jumps and air dashes (for aerial models).

Firewall
A combo that is very effective against enemies who move quickly, or attack at close range. The most important thing about this strategy is to not let your opponent get too close to you. or better yet, let them get close, then wail on them with the wall pod. use the wall bomb to halt advances and as an offensive weapon (move the bomb target to near or in front of your enemy), and use your gun any time you see fit.
 * Robo: a high power robo is best, but any robo will work.
 * Gun: there are several guns you can use, but some of the best ones are the long range kind. The afterburner gun is good for this.
 * Bomb: wall bomb.
 * Pod: wall pod.
 * Legs: formula legs are suggested, but you can use others if you wish.

Flying with the eagles

 * Robo: any lightning sky model.
 * Gun: eagle gun.
 * Bomb: bombs that can stun or trap enemies or any bomb with a "C" type blast work well.
 * Pod: same as the bomb, but don't use the buster pod.
 * Legs: plus one legs.

A combo that sets traps and deals good damage if it works. Fly around with the lightning sky air dash, while shooting eagle shots. Normally, this would cause you to need a quick cool down from the gun, but since you are flying, you don't have to. Set up several eagles, then trap or stun your enemy with bombs and pods, and let the eagles do the rest. Don't forget that you can air dash twice with the plus one legs.

Sniper Set

 * Robo: any high flying robo. Big boys, aerial beauties, and old timers are best. Try and choose the "power" model, or the "speed" model if you can't get that.
 * Gun: three way gun (early in the game, switch out quickly) homing star gun (good weapon in general, but best in holoseums without much to block your shots) or the sniper gun (use this anytime the homing star gun is ineffective).
 * Bomb: bombs with a "C" type blast are good. Stunning and freeze bombs are also nice choices. Otherwise, stick with any bomb with an "H" type blast so you can knock your enemies out of cover.
 * Pod: the sky and ground freeze pods are very effective (especially the sky pod). If you don't have either of those, the coboose pod C is a good one, or you can use any pod that traps enemies.
 * Leg: the long thrust, plus one, or wide jump legs are recommended.

A reliable combo that is nice when you have to keep your distance from your enemies. It is also very flexible. Deploy pods and use bombs to freeze enemies or launch them into vulnerable positions, then open fire. You can also attack from the air, which works well most of the time. When using the homing star gun, remember that in the air it spreads and is effective against horizontal moving enemies. The ground shot is better against jumping enemies and it deals more damage, so use when enemies are stunned.

Ground Zero (uses illegal parts)
robo: the carrot is recommended, but the snipe will work as well.

gun: laser ripple gun

bomb: deva bomb (this one is vital. make no substitutes!)

pod: your choice, but any pod that traps enemies is best. remember to use illegal parts, 'cuz you want to go all out on the illegal parts

legs: your choice, but I recommend the hadron legs.

A super powered illegal combo that cannot be used until late in the game. the deva bomb is what this rotates around. it's high damage and giant blast radius make it deadly. run up to your enemies (trap them with pods if necessary) and stun them with laser ripples. the laser ripple gun has a very long stun time, so use that time to fire a bomb on top of your enemy, then run away! this will deal good damage. if you want, you can also shoot the bomb, then keep your enemy stunned within the blast radius instead.
