This being is the non-stacked composite of Omi, Rai, Kimiko and Clay at the end of the series with access to all the powers of the shen gong wu (without their being any items to steal or lose).
A) What is the weakest being to beat this composite?
B) What is the strongest being this composite can defeat.
Fight takes place in a Khazan that has been terraformed to have a tiny lake and greenery (to help Omi's water powers out a bit)
Both fights have two different versions: one where all the shen gong wu are initially inactive and must be called out to be used like in the show and the other where all the items are already on (most importantly things like Shard of Lightning and crystal glasses, etc.)
