Well I don't know what the select trick is (awaits onslaught of comments curled in a corner).
However here is my strategy for the Admin Staff in an effor to win a spot in their hearts or on their hit list one or the other:
Del Murder does not want you to get close to him. He uses the Enforce Strike to throw exploding bursts of light at you. If they hit a wall, they split into three smaller shots and are reflected, so watch out. If you get close to him, he fires an Enforce strike at you and jumps to the other side of the room. The LoonY BloW is his weak point. Defeat him to get the Enforce strike. (The LoonY BloW sounds cheap so I'll just stick with what works distance attacks and paralyze. It'll be the Ruby Weapon battle all over again)
Kishi is the largest of the admins, and he can throw fireballs from his tentacles for some reason. The flame wheel is four fireballs that he throws aimed where you are standing. He can also grab you with a tentacle and drain your life, healing himself. The psycho shooter will cause him a lot of pain, and you get the Flame wheel when you beat him. (Sounds like I need to be jumping constantly and moving as well as staying close to him. So the Enforce Strike gained from defeating Del Murder will come in handy not to mention paralyze to move in time away from the tentacles to preven health drain.)
Leeza is fought in an icy room, so be careful not to slip. The Feline Laser bounces around the room, so you will have to watch out for it while dodging the icicles she makes as well. The cosmic shield is very effective against her. Defeat her to get the Feline Laser. (This is just fitting to well. It's like going in the right order for Mega Man lol. I'll use the Fire Wheel I gained from Kishi. Obviously this boss has a weakness for fire being in an ice palace. So distance attacks with the Fire Wheel will give a good amount of damage and enough time for me to time my dodges of the icicles and laser)
Loony BoB carries a spear, but he doesn't poke you with it. He spins it to make small tornadoes with his LoonY BloW that block your shots and then fires them at you. He makes a couple then jumps around. Hit him while he jumps with the Knight blow. It is easiest to do this while he is jumping. Defeat him to earn the LoonY BloW. (This sounds like a fairly easy boss to defeat. Just takes timing and practice. I think the Feline Laser I just earned will do a good job as well as it will reflect and have a better chance of hitting him as he is jumping stunting his jump and stunning him temporarily allowing me to jump in close and use the Enforce Strike I earned first.)
Psychotic attacks with electric shocks. He moves around a lot, only stopping to fire the Psycho shooter, a forward electric burst that can go through walls. Sometimes while in the air he will use BaoTW call, where he fires a very large shot at you that explodes on impact. Run to avoid it. He is weak to the Feline Laser. Defeating him earns you the Psycho Shooter. (Weak agains the Feline Laser. That's even better, that was going to be my plan. Feline Laser it is, and a steady hand for dodging the shooter and BaoTW call.)
As Rantzien was recently made an Admin, he still has the appearence of a Knight. He swings his metal ball to the ground to send rocks at you with his Knight Blow, and he can also throw his shield like a boomerang with his Viking strike. Sometimes he charges at you with Knight rush. He is most vulnerable to the flame wheel. He gives the Knight Blow when defeated. (What seems to be one of the harder Admin, the youngest/newest always are. So flame wheel it is to break through the rocks...or maybe the Psycho Shooter as it would pass right through the rocks and hit him as he is finishing his Knight Blow. Either way I think I'm good.)
Roogle is fought in low gravity, so you can jump higher than normal. His cosmic shield is a shield of stars that he can also fire at you. He also can use his soul rush to make stars fall from the ceiling. The Strawberry Trident is his only fear. Defeat him to get the cosmic shield. (Hmmm...arguably one of the hardest ones. He's got both distance and close range covered. I may have to defeat Shlup first and use the Strawberry Trident against him despite my tendency towards the more unorthadoxed.)
Shlup is fought underwater, and if you jump too high you will hit spikes which will deal a lot of damage, so take caution. She swims around a lot and throws her strawberry trident at you. After she throws it she has to go get it, but she throws a strawberry at you as she swims towards it, so be careful. The Enforce strike is her weak point. Defeat her to get the Strawberry trident. (Again...an interestingly hard battle. I would rather have the Cosmic Sheild for her to deflect the Trident but I guess my superior dodging skills will just have to do as well as the other gamit of weapons that are now mine. I think using the flame wheel to make her move as well as the Enforced Strike at close range will do her in)
All of them being defeated I move onto to claim the prize I've sought...a chance to come among their ranks and add yet another boss that must be defeated for a spot on in the final bosses in Admin Man 3.
