Princess Ayeka and RPGs

[Kokoro]

I have both copies of Tenchi Muyo RPG and Tenchi Universe RPG, and I'm working on a project to start converting all the characters I know to Big Eyes Small Mouth 4 (since these games are based on the Revised Second Edition).  However, I've come across an interesting situation.  I would have thought that the characters would be mostly the same between these two games, since the character is the same, just the official backgrounds are different.

In Tenchi Muyo RPG, Ayeka has a Body of 4, Mind of 4, and Soul of 7.
In Tenchi Universe RPG, Ayeka has a Body of 5, Mind of 4, and Soul of 6.

The point values calculate to the same usage, so that's only a minor detail. However, when I'm scanning down towards the Special Powers section, things are wildly different.
In Tenchi Muyo RPG, there is an attack called "Energy Fist", Damage: 50, and another attack called "Energy Balls", Damage 30.
In Tenchi Universe RPG, there's an attack called "Log Zap", Damage: 50, and another attack called "Emerald Energy Blast", Damage 60

It appears to me that the Tenchi Universe version of Ayeka is more powerful than in the OVA setting.  The higher Body stat would give Ayeka more strength for Unarmed attacks, but the lower Soul stat would maker her Special Abilities weaker, but not by much.

Anyway, do you agree with my assessment?  Or based on everything you all know, what would you recommend?  I realize that BESM has had two revisions since these characters were imported into the system, and I'll have to do some other adjustments to ensure they are all balanced properly.

I'll have my DND buddies take a look since I know nothing about it
