Beetlejuice can only send people to dead world places I think, no where in the living plane. He can't even get to the living world himself without Beetlejuice being said three times.

And if he shrinks himself down to a microbe tall, Yusuke blows up the entire area. Beetlejuice would be killed by a mere fraction of the aftermath of a blast at that size.

Beetlejuice can teleport around (I think), so he can easily dodge all these Spirit Gun blasts. Plus if Yususke blows everything up, doesn't he blow himself up? Beetlejuice could be a microbe tall and sitting on his shoulder.

He doesn't only have Spirit Gun. He has Spirit Shotgun (Many, many Spirit Guns shooting everywhere), and Spirit Wave (Big Boom). The wave would kill Beetlejuice. If he is on Yusuke's shoulder, the blast would kill him since he is so tiny it would destroy him when it barely does anything to Yusuke.

If they re both unaware of each other abilities an duel on a flat plain, Yusuke wins.

Otherwise, it becomes like the above discussion.

Yes. And Beetlejuice could also just tie Yusuke's shoelaces together, open a door to the Netherworld in front of Yusuke, then stand behind the door. Either something would com ou and eat Yusuke, or when Yusuke moves to go around behind the door, he trip over his shoelaces, falls into the door, and Beetlejuice closes it. Then something eats Yusuke.

Yusuke would kill anything Beetlejuice tries to unleash on him, then go kill Beetlejuice.

Weren't you one of the ones arguing that in DBZ, even when turned into small objects they still have their power? Beetlejuice was one of the most powerful ghosts, so if he was tiny it wouldn't negate his powers or strength. He would make rock pillars shoot from the ground, bring the roof down on Yusuke's head, and basically smash him flat or run him through pretty quickly. As to the Spirit Weapons, he could make rock walls shoot up to block them if they where about to hit him and do damage, or he could teleport out of the way to the opposite side of where Yusuke shot the attack, or out of range and then come back in once the attack is gone.

Even if Beetlejuice is full power (By that, I mean he can take as many hits as he can when he is normal size), he still isn't very strong at taking hits (At least at Yusuke's level). Weak things Yusuke does will kill him.

Yusuke would destroy anything Beetlejuice tries to throw at him. And a Spirit gun would easily go through a rock wall. And out of range is probably some where out in space.

Yes, Beetlejuice was so great, he was banished from the depths of Hell and to the mortal plane, only to be released when, depending on the cartoon or movie, a lonely goth girl needed a friend or a ghost couple wanted to get a family out of their house, respectively. And I didn't state Beeteljuice would summon the Netherworld monsters; I'm just stating that he would merely open the door and que sera.

I'm gunna have to go with the Yusuke crowd FZ...I can't believe you haven't seen an episode of Yu Yu Hakusho...he gets more powerful as he gets more 'losering', so whatever Beetlejuice throws at him would either not phase him or push him to the point of his second (or third, or fourth...) power blast.
